Flu? Malaria? Disease forecasters look to the sky


NEW YORK (AP) — Only a 10 percent chance of showers today, but a 70 percent chance of flu next month.


That's the kind of forecasting health scientists are trying to move toward, as they increasingly include weather data in their attempts to predict disease outbreaks.


In one recent study, two scientists reported they could predict — more than seven weeks in advance — when flu season was going to peak in New York City. Theirs was just the latest in a growing wave of computer models that factor in rainfall, temperature or other weather conditions to forecast disease.


Health officials are excited by this kind of work and the idea that it could be used to fine-tune vaccination campaigns or other disease prevention efforts.


At the same time, experts note that outbreaks are influenced as much, or more, by human behavior and other factors as by the weather. Some argue weather-based outbreak predictions still have a long way to go. And when government health officials warned in early December that flu season seemed to be off to an early start, they said there was no evidence it was driven by the weather.


This disease-forecasting concept is not new: Scientists have been working on mathematical models to predict outbreaks for decades and have long factored in the weather. They have known, for example, that temperature and rainfall affect the breeding of mosquitoes that carry malaria, West Nile virus and other dangerous diseases.


Recent improvements in weather-tracking have helped, including satellite technology and more sophisticated computer data processing.


As a result, "in the last five years or so, there's been quite an improvement and acceleration" in weather-focused disease modeling, said Ira Longini, a University of Florida biostatistician who's worked on outbreak prediction projects.


Some models have been labeled successes.


In the United States, researchers at Johns Hopkins University and the University of New Mexico tried to predict outbreaks of hantavirus in the late 1990s. They used rain and snow data and other information to study patterns of plant growth that attract rodents. People catch the disease from the droppings of infected rodents.


"We predicted what would happen later that year," said Gregory Glass, a Johns Hopkins researcher who worked on the project.


More recently, in east Africa, satellites have been used to predict rainfall by measuring sea-surface temperatures and cloud density. That's been used to generate "risk maps" for Rift Valley fever — a virus that spreads from animals to people and in severe cases can cause blindness or death. Researchers have said the system in some cases has given two to six weeks advance warning.


Last year, other researchers using satellite data in east Africa said they found that a small change in average temperature was a warning sign cholera cases would double within four months.


"We are getting very close to developing a viable forecasting system" against cholera that can help health officials in African countries ramp up emergency vaccinations and other efforts, said a statement by one of the authors, Rita Reyburn of the International Vaccine Institute in Seoul, South Korea.


Some diseases are hard to forecast, such as West Nile virus. Last year, the U.S. suffered one of its worst years since the virus arrived in 1999. There were more than 2,600 serious illnesses and nearly 240 deaths.


Officials said the mild winter, early spring and very hot summer helped spur mosquito breeding and the spread of the virus. But the danger wasn't spread uniformly. In Texas, the Dallas area was particularly hard-hit, while other places, including some with similar weather patterns and the same type of mosquitoes, were not as affected.


"Why Dallas, and not areas with similar ecological conditions? We don't really know," said Roger Nasci of the Centers for Disease Control and Prevention. He is chief of the CDC branch that tracks insect-borne viruses.


Some think flu lends itself to outbreak forecasting — there's already a predictability to the annual winter flu season. But that's been tricky, too.


Seasonal flu reports come from doctors' offices, but those show the disease when it's already spreading. Some researchers have studied tweets on Twitter and searches on Google, but their work has offered a jump of only a week or two on traditional methods.


In the study of New York City flu cases published last month in the Proceedings of the National Academy of Sciences, the authors said they could forecast, by up to seven weeks, the peak of flu season.


They designed a model based on weather and flu data from past years, 2003-09. In part, their design was based on earlier studies that found flu virus spreads better when the air is dry and turns colder. They made calculations based on humidity readings and on Google Flu Trends, which tracks how many people are searching each day for information on flu-related topics (often because they're beginning to feel ill).


Using that model, they hope to try real-time predictions as early as next year, said Jeffrey Shaman of Columbia University, who led the work.


"It's certainly exciting," said Lyn Finelli, the CDC's flu surveillance chief. She said the CDC supports Shaman's work, but agency officials are eager to see follow-up studies showing the model can predict flu trends in places different from New York, like Miami.


Despite the optimism by some, Dr. Edward Ryan, a Harvard University professor of immunology and infectious diseases, is cautious about weather-based prediction models. "I'm not sure any of them are ready for prime time," he said.

Wall Street dips as profits booked after rally

NEW YORK (Reuters) - Stocks edged lower on Thursday as investors locked in gains after a rally Wednesday, which was spurred by a deal by U.S. lawmakers to avert a "fiscal cliff" of austerity measures that had been due to kick in this year.


Losses were limited, however, by better-than-expected data that showed U.S. private-sector employers added 215,000 jobs in December. That was well above economists' expectations for a gain of 133,000 jobs, according to a Reuters survey.


"The report now sets the stage as we expect a strong non-farm payroll reading on Friday," said Andrew Wilkinson, chief economic strategist at Miller Tabak & Co in New York


The ADP report beat forecasts partly due to "a snapback from (superstorm) Sandy, although we prefer to stick to our line of thought that says the economy is gaining momentum rather than losing it regardless of the impact of fiscal talks in Washington," he said.


The key payrolls report is due on Friday. A Reuters survey forecasts non-farm payrolls rose to 150,000 last month, from 146,000 in November.


A separate report Thursday showed the number of Americans filing new claims for unemployment benefits rose last week, but the data was too distorted by year-end holidays to offer a clear read of labor market conditions.


The Dow Jones industrial average <.dji> was down 45.92 points, or 0.34 percent, at 13,366.63. The Standard & Poor's 500 Index <.spx> was down 3.62 points, or 0.25 percent, at 1,458.80. The Nasdaq Composite Index <.ixic> was down 8.15 points, or 0.26 percent, at 3,104.11.


Wall Street began the new year Wednesday with a rally and their best performance in more than a year, sparked by a last-minute deal in Washington to avert a fiscal cliff of automatic massive tax hikes and spending cuts that, in the worst-case scenario, would have hurt the nation's economic growth.


The minutes of the Federal Reserve's policy meeting last month will be released at 2:00 p.m. EST (1900 GMT). The minutes will give details on the discussions of the Federal Open Market Committee's December 11-12 meeting.


U.S. retailer Costco Wholesale Corp reported a better-than-expected 9 percent rise in December sales at stores open at least a year, mainly helped by an additional sales day in the reporting period. Costco shares rose 1.3 percent to $102.80.


Gap Inc will buy women's fashion boutique Intermix Inc for $130 million to enter the luxury clothes market, the Wall Street Journal reported. The stock rose 3 percent to $32.28.


Family Dollar Stores Inc reported a lower-than-expected quarterly profit as its emphasis on selling more everyday items like cigarettes and soft drinks put pressure on margins. The stock fell 12 percent to $56.47.

Used to Hardship, Latvia Accepts Austerity, and Its Pain Eases





RIGA, Latvia — When a credit-fueled economic boom turned to bust in this tiny Baltic nation in 2008, Didzis Krumins, who ran a small architectural company, fired his staff one by one and then shut down the business. He watched in dismay as Latvia’s misery deepened under a harsh austerity drive that scythed wages, jobs and state financing for schools and hospitals.




But instead of taking to the streets to protest the cuts, Mr. Krumins, whose newborn child, in the meantime, needed major surgery, bought a tractor and began hauling wood to heating plants that needed fuel. Then, as Latvia’s economy began to pull out of its nose-dive, he returned to architecture and today employs 15 people — five more than he had before. “We have a different mentality here,” he said.


Latvia, feted by fans of austerity as the country-that-can and an example for countries like Greece that can’t, has provided a rare boost to champions of the proposition that pain pays.


Hardship has long been common here — and still is. But in just four years, the country has gone from the European Union’s worst economic disaster zone to a model of what the International Monetary Fund hails as the healing properties of deep budget cuts. Latvia’s economy, after shriveling by more than 20 percent from its peak, grew by about 5 percent last year, making it the best performer in the 27-nation European Union. Its budget deficit is down sharply and exports are soaring.


“We are here to celebrate your achievements,” Christine Lagarde, the chief of the International Monetary Fund, told a conference in Riga, the capital, this past summer. The fund, which along with the European Union financed a bailout of 7.5 billion euros for the country at the end of 2008, is “proud to have been part of Latvia’s success story,” she said.


When Latvia’s economy first crumbled, it wrestled with many of the same problems faced since by other troubled European nations: a growing hole in government finances, a banking crisis, falling competitiveness and big debts — though most of these were private rather than public as in Greece.


Now its abrupt turn for the better has put a spotlight on a ticklish question for those who look to orthodox economics for a solution to Europe’s wider economic woes: Instead of obeying any universal laws of economic gravity, do different people respond differently to the same forces?


Latvian businessmen applaud the government’s approach but doubt it would work elsewhere.


“Economics is not a science. Most of it is in people’s heads,” said Normunds Bergs, chief executive of SAF Tehnika, a manufacturer that cut management salaries by 30 percent. “Science says that water starts to boil at 100 degrees Celsius; there is no such predictability in economics.”


In Greece and Spain, cuts in salaries, jobs and state services have pushed tempers beyond the boiling point, with angry citizens staging frequent protests and strikes. Britain, Portugal, Italy and also Latvia’s neighbor Lithuania, meanwhile, have bubbled with discontent over austerity.


But in Latvia, where the government laid off a third of its civil servants, slashed wages for the rest and sharply reduced support for hospitals, people mostly accepted the bitter medicine. Prime Minister Valdis Dombrovskis, who presided over the austerity, was re-elected, not thrown out of office, as many of his counterparts elsewhere have been.


The cuts calmed fears on financial markets that the country was about to go bankrupt, and this meant that the government and private companies could again get the loans they needed to stay afloat. At the same time, private businesses followed the government in slashing wages, which made the country’s labor force more competitive by reducing the prices of its goods. As exports grew, companies began to rehire workers.


Economic gains have still left 30.9 percent of Latvia’s population “severely materially deprived,” according to 2011 data released in December by Eurostat, the European Union’s statistics agency, second only to Bulgaria. Unemployment has fallen from more than 20 percent in early 2010, but was still 14.2 percent in the third quarter of 2012, according to Eurostat, and closer to 17 percent if “discouraged workers” are included. This is far below the more than 25 percent jobless rate in Greece and Spain but a serious problem nonetheless.


This article has been revised to reflect the following correction:

Correction: January 2, 2013

An earlier version of this article misstated the amount of a bailout given to Latvia in 2008. It was 7.5 billion euros, not $7.5 billion.

Apple testing new iPhone, iOS 7: report






(Reuters) – Apple Inc has started testing a new iPhone and the next version of its iOS software, news website The Next Web reported.


Apple shares were up 2.6 percent at $ 546.06 in premarket trading. The stock closed at $ 532.17 on the Nasdaq on Monday.






Application developers have found in their app usage logs references to a new iPhone identifier, iPhone 6.1, running iOS 7 operating system, the website reported. (http://r.reuters.com/fyd94t)


Apple‘s iPhone 5 bears the identifiers “iPhone 5.1″ and “iPhone 5.2″ and is powered by iOS 6 operating system.


Developer logs show that the app requests originate from an internet address on Apple’s Cupertino campus, suggesting that Apple engineers are testing compatibility for some of the popular apps, the website said.


“Although OS and device data can be faked, the unique IP footprint leading back to Apple’s Cupertino campus leads us to believe this is not one of those attempts,” the website said.


Apple launched iPhone 5 in September and it has been reported that the new iPhone will be released in the middle of 2013.

Kate and William Spent New Year's Eve Apart









01/02/2013 at 10:30 AM EST



The Duke and Duchess of Cambridge kicked off 2013 apart from one other – with helicopter pilot William participating in an attempted rescue of a man who had been swept out to sea in the first minutes of the New Year.

William, 30, was part of an RAF search and rescue crew scrambled at around 12:30 a.m. Tuesday to help find a 41-year-old dog walker who had gotten lost in raging seas at Blackpool, Lancashire. Sadly, the RAF Sea King helicopter was unable to find the stricken man, and searches by coastguard crews were continuing into early Wednesday.

Kate, meanwhile, was believed to be ringing in the new year at home with her parents in Bucklebury, Berkshire, where she and William spent their Christmas Day.

At his RAF base in North Wales, William was on the first responders' shift from early New Year's Eve into the start of the New Year, PEOPLE was told. He was also to spend a second 24-hour shift on or near the base as part of a second back-up crew.

As for Kate's New Year's Eve, she was seen at a gas station stocking up on Mini Cheddars snacks, according to one eyewitness.

William is expected to spend much of the early part of the year "concentrating on his flying," a Palace source tells PEOPLE, and he and Kate are not expected at any royal engagements in the first few weeks of '13.

Brain image study: Fructose may spur overeating


This is your brain on sugar — for real. Scientists have used imaging tests to show for the first time that fructose, a sugar that saturates the American diet, can trigger brain changes that may lead to overeating.


After drinking a fructose beverage, the brain doesn't register the feeling of being full as it does when simple glucose is consumed, researchers found.


It's a small study and does not prove that fructose or its relative, high-fructose corn syrup, can cause obesity, but experts say it adds evidence they may play a role. These sugars often are added to processed foods and beverages, and consumption has risen dramatically since the 1970s along with obesity. A third of U.S. children and teens and more than two-thirds of adults are obese or overweight.


All sugars are not equal — even though they contain the same amount of calories — because they are metabolized differently in the body. Table sugar is sucrose, which is half fructose, half glucose. High-fructose corn syrup is 55 percent fructose and 45 percent glucose. Some nutrition experts say this sweetener may pose special risks, but others and the industry reject that claim. And doctors say we eat too much sugar in all forms.


For the study, scientists used magnetic resonance imaging, or MRI, scans to track blood flow in the brain in 20 young, normal-weight people before and after they had drinks containing glucose or fructose in two sessions several weeks apart.


Scans showed that drinking glucose "turns off or suppresses the activity of areas of the brain that are critical for reward and desire for food," said one study leader, Yale University endocrinologist Dr. Robert Sherwin. With fructose, "we don't see those changes," he said. "As a result, the desire to eat continues — it isn't turned off."


What's convincing, said Dr. Jonathan Purnell, an endocrinologist at Oregon Health & Science University, is that the imaging results mirrored how hungry the people said they felt, as well as what earlier studies found in animals.


"It implies that fructose, at least with regards to promoting food intake and weight gain, is a bad actor compared to glucose," said Purnell. He wrote a commentary that appears with the federally funded study in Wednesday's Journal of the American Medical Association.


Researchers now are testing obese people to see if they react the same way to fructose and glucose as the normal-weight people in this study did.


What to do? Cook more at home and limit processed foods containing fructose and high-fructose corn syrup, Purnell suggested. "Try to avoid the sugar-sweetened beverages. It doesn't mean you can't ever have them," but control their size and how often they are consumed, he said.


A second study in the journal suggests that only severe obesity carries a high death risk — and that a few extra pounds might even provide a survival advantage. However, independent experts say the methods are too flawed to make those claims.


The study comes from a federal researcher who drew controversy in 2005 with a report that found thin and normal-weight people had a slightly higher risk of death than those who were overweight. Many experts criticized that work, saying the researcher — Katherine Flegal of the Centers for Disease Control and Prevention — painted a misleading picture by including smokers and people with health problems ranging from cancer to heart disease. Those people tend to weigh less and therefore make pudgy people look healthy by comparison.


Flegal's new analysis bolsters her original one, by assessing nearly 100 other studies covering almost 2.9 million people around the world. She again concludes that very obese people had the highest risk of death but that overweight people had a 6 percent lower mortality rate than thinner people. She also concludes that mildly obese people had a death risk similar to that of normal-weight people.


Critics again have focused on her methods. This time, she included people too thin to fit what some consider to be normal weight, which could have taken in people emaciated by cancer or other diseases, as well as smokers with elevated risks of heart disease and cancer.


"Some portion of those thin people are actually sick, and sick people tend to die sooner," said Donald Berry, a biostatistician at the University of Texas MD Anderson Cancer Center in Houston.


The problems created by the study's inclusion of smokers and people with pre-existing illness "cannot be ignored," said Susan Gapstur, vice president of epidemiology for the American Cancer Society.


A third critic, Dr. Walter Willett of the Harvard School of Public Health, was blunter: "This is an even greater pile of rubbish" than the 2005 study, he said. Willett and others have done research since the 2005 study that found higher death risks from being overweight or obese.


Flegal defended her work. She noted that she used standard categories for weight classes. She said statistical adjustments were made for smokers, who were included to give a more real-world sample. She also said study participants were not in hospitals or hospices, making it unlikely that large numbers of sick people skewed the results.


"We still have to learn about obesity, including how best to measure it," Flegal's boss, CDC Director Dr. Thomas Frieden, said in a written statement. "However, it's clear that being obese is not healthy - it increases the risk of diabetes, heart disease, cancer, and many other health problems. Small, sustainable increases in physical activity and improvements in nutrition can lead to significant health improvements."

Wall Street surges in wake of fiscal pact

NEW YORK (Reuters) - Stocks surged on the first trading day of 2013 after lawmakers agreed a deal to avoid massive tax hikes and spending cuts that had threatened to hurt economic growth.


The gains come after stocks ended 2012 with their strongest day in more than a month, which put the S&P 500 up 13.4 percent for the year, after a flat performance in 2011.


Late on Tuesday, the House of Representatives voted for a bill that will raise taxes on wealthy individuals and families and preserve certain benefits.


The vote averted immediate austerity measures, like tax hikes for almost all U.S. households, although it didn't resolve other political showdowns on the budget due in coming months. Spending cuts of $109 billion in military and domestic programs were only delayed for two months.


"Many investors are feeling confident heading into 2013 following a year of strong equity market returns, and the recently signed deal," said Jonathan Golub, strategist at UBS in New York.


"Unfortunately, our sense is that the most important structural issues will continue to be pushed off into the future, leaving significant uncertainty about the long-term direction of the economy and corporate profits."


The Dow Jones industrial average <.dji> was up 255.72 points, or 1.95 percent, at 13,359.86. The Standard & Poor's 500 Index <.spx> was up 28.75 points, or 2.02 percent, at 1,454.94. The Nasdaq Composite Index <.ixic> was up 75.18 points, or 2.49 percent, at 3,094.70.


Bank shares rose following news that U.S. regulators are close to securing another multibillion-dollar settlement with the largest banks to resolve allegations that they unlawfully cut corners when foreclosing on delinquent borrowers.


Bank of America Corp rose 4 percent to $12.06 and Wells Fargo shares added 2.4 percent to $35. JPMorgan Chase & Co shares rose 3 percent to $44.96.


Boosting the technology sector, Apple shares rose on a report that the most valuable technology company has started testing a new iPhone and the next version of its iOS software.The stock was up 3.9 percent at $552.86.


Shares of Zipcar Inc jumped 48 percent to $12.21 after Avis Budget Group Inc said it would buy Zipcar for about $500 million in cash to compete with larger rivals Hertz and Enterprise Holdings Inc.


On the macroeconomic front, U.S. manufacturing expanded slightly in December, rebounding from an unexpected contraction the prior month, an industry report showed on Wednesday.


A separate report showed U.S. construction spending fell in November for the first time in eight months, as an extended bout of weakness in the business sector outweighed modest growth in outlays on residential projects. The equity market's reaction to both reports was muted.


On the last day of trading in 2012, the Dow Jones industrial average <.dji> gained 166.03 points, or 1.28 percent, to close at 13,104.14. The Standard & Poor's 500 Index <.spx> gained 23.76 points, or 1.69 percent, to finish at 1,426.19. The Nasdaq Composite Index <.ixic> gained 59.20 points, or 2.00 percent, to close at 3,019.51.


In 2012, the Dow advanced 7.3 percent, while the Nasdaq climbed 15.9 percent.

India Ink: Delhi Starts Women's Hotline

The Delhi government started a 24-hour hotline for women on Monday, in an effort to address sexual harassment and violence against women in the city.

Women needing help in the nation’s capital can now dial 181, and a counselor will offer relevant phone numbers of government agencies and contact the police if necessary.

“Any lady in any sort of problem” can call, said Jhuma Ganguly, a duty counselor at the hotline. “We’ll inform other agencies to take action.”

The capital has been roiled with protests after the gang rape of a 23-year-old student on Dec. 16. After she died on Saturday, the government charged six suspects with rape and murder.

Protesters and activists have demanded that the law enforcement and judicial systems be overhauled to combat sexual violence in the country.

Some critics acknowledged that the helpline was a positive step but called it a political quick fix that did nothing to address the fact that the police often dissuade women from filing complaints about sex crimes and that rape investigations and court cases drag on.

In a span of 12 hours, the hotline has received some 2,000 calls since 6 a.m., said Mrityunjay Kumar, a counselor at the helpline. He added, however, that while some were genuine complaints, many of the calls were to check that the hotline worked.

Mr. Kumar said that two operators would be available around the clock and were connected to all police stations in the city.

Kim Kardashian Steps Out for New Year's Party after Pregnancy Announcement















01/01/2013 at 10:20 AM EST







Kanye West and Kim Kardashian


Denise Truscello/WireImage


The year 2012 was good for Kim Kardashian. But, oh baby, is she ready for 2013! 

"It's been so exciting," she told PEOPLE of the whirlwind of emotions she's felt since finding out she was pregnant. "We're very, very happy." 

With just a hint of a baby bump showing under her form fitting black Julian McDonald dress, the reality star rang in the new year in Las Vegas with the man she's spent 2012 with: Beau and baby daddy Kanye West.

"I wish I could share a drink with you all, but I can't for a little while," she told the crowd at Mirage's 1 OAK just before leading a countdown to 2013. 

With the crowd cheering and confetti flying as the clock struck midnight, Kardashian stood on an elevated banquet adjacent to the deejay booth and passionately kissed West. And for the next 25 minutes, the deejay played nothing but West's songs – much to the delight of his pregnant girlfriend, who smiled and sang along.

As the night continued, the duo rarely left each other's side, with Kardashian dancing behind West while her party sipped Grey Goose cocktails. Kardashian stuck to water as the Grammy award-winning rapper occasionally rubbed her belly.

Her VIP table littered with party hats, streamers and black and gold balloons, Kardashian appeared happy throughout the night, kissing West and chatting with friends and family in attendance, including mom Kris Jenner, longtime friend Brittny Gastineau and Lance Bass.

Now that the new year has begun, Kardashian is working on being healthy for her unborn child. 

"I've felt good. I've felt no morning sickness but it isn't the easiest," she said. "People always say pregnancy is so easy and fun. It's definitely an adjustment; It's learning about your body, but I've felt really good."

While the announcement of Kardashian's pregnancy came as a surprise to a lot of people, she doesn't want to be surprised when it comes the sex of the baby.

She said, "Of course I do want to know!"

Clinton receiving blood thinners to dissolve clot


WASHINGTON (AP) — Doctors treating Secretary of State Hillary Rodham Clinton for a blood clot in her head said blood thinners are being used to dissolve the clot and they are confident she will make a full recovery.


Clinton didn't suffer a stroke or neurological damage from the clot that formed after she suffered a concussion during a fainting spell at her home in early December, doctors said in a statement Monday.


Clinton, 65, was admitted to New York-Presbyterian Hospital on Sunday when the clot turned up on a follow-up exam on the concussion, Clinton spokesman Phillipe Reines said.


The clot is located in the vein in the space between the brain and the skull behind the right ear. She will be released once the medication dose for the blood thinners has been established, the doctors said.


In their statement, Dr. Lisa Bardack of the Mount Kisco Medical Group and Dr. Gigi El-Bayoumi of George Washington University said Clinton was making excellent progress and was in good spirits.


Clinton's complication "certainly isn't the most common thing to happen after a concussion" and is one of the few types of blood clots in the skull or head that are treated with blood thinners, said Dr. Larry Goldstein, a neurologist who is director of Duke University's stroke center. He is not involved in Clinton's care.


The area where Clinton's clot developed is "a drainage channel, the equivalent of a big vein inside the skull. It's how the blood gets back to the heart," Goldstein said.


Blood thinners usually are enough to treat the clot and it should have no long-term consequences if her doctors are saying she has suffered no neurological damage from it, Goldstein said.


Clinton returned to the U.S. from a trip to Europe, then fell ill with a stomach virus in early December that left her severely dehydrated and forced her to cancel a trip to North Africa and the Middle East. Until then, she had canceled only two scheduled overseas trips, one to Europe after breaking her elbow in June 2009 and one to Asia after the February 2010 earthquake in Haiti.


Her condition worsened when she fainted, fell and suffered a concussion while at home alone in mid-December as she recovered from the virus. It was announced Dec. 13.


This isn't the first time Clinton has suffered a blood clot. In 1998, midway through her husband's second term as president, Clinton was in New York fundraising for the midterm elections when a swollen right foot led her doctor to diagnose a clot in her knee requiring immediate treatment.


Clinton had planned to step down as secretary of state at the beginning of President Barack Obama's second term. Whether she will return to work before she resigns remained a question.


Democrats are privately if not publicly speculating: How might her illness affect a decision about running for president in 2016?


After decades in politics, Clinton says she plans to spend the next year resting. She has long insisted she had no intention of mounting a second campaign for the White House four years from now. But the door is not entirely closed, and she would almost certainly emerge as the Democrat to beat if she decided to give in to calls by Democratic fans and run again.


Her age — and thereby health — would probably be a factor under consideration, given that Clinton would be 69 when sworn in, if she were elected in 2016. That might become even more of an issue in the early jockeying for 2016 if what started as a bad stomach bug becomes a prolonged, public bout with more serious infirmity.


Not that Democrats are willing to talk openly about the political implications of a long illness, choosing to keep any discussions about her condition behind closed doors. Publicly, Democrats reject the notion that a blood clot could hinder her political prospects.


"Some of those concerns could be borderline sexist," said Basil Smikle, a Democratic strategist who worked for Clinton when she was a senator. "Dick Cheney had significant heart problems when he was vice president, and people joked about it. He took the time he needed to get better, and it wasn't a problem."


It isn't uncommon for presidential candidates' health — and age — to be an issue. Both in 2000 and 2008, Sen. John McCain, R-Ariz., had to rebut concerns he was too old to be commander in chief or that his skin cancer could resurface.


Two decades after Clinton became the first lady, signs of her popularity — and her political strength — are ubiquitous.


Obama had barely declared victory in November when Democrats started zealously plugging Clinton as their strongest White House contender four years from now, should she choose to take that leap.


"Wouldn't that be exciting?" House Democratic leader Nancy Pelosi declared in December. "I hope she goes. Why wouldn't she?"


Even Republicans concede that were she to run, Clinton would be a force to be reckoned with.


"Trying to win that will be truly the Super Bowl," Newt Gingrich, the former House Speaker and 2012 GOP presidential candidate, said in December. "The Republican Party today is incapable of competing at that level."


Americans admire Clinton more than any other woman in the world, according to a Gallup poll released Monday — the 17th time in 20 years that Clinton has claimed that title. And a recent ABC News/Washington Post poll found that 57 percent of Americans would support Clinton as a candidate for president in 2016, with just 37 percent opposed. Websites have already cropped up hawking "Clinton 2016" mugs and tote bags.


Beyond talk of future politics, Clinton's three-week absence from the State Department has raised eyebrows among some conservative commentators who questioned the seriousness of her ailment after she canceled planned Dec. 20 testimony before Congress on the deadly attack on the U.S. diplomatic mission in Benghazi, Libya.


Clinton had been due to discuss with lawmakers a scathing report she had commissioned on the attack. It found serious failures of leadership and management in two State Department bureaus were to blame for insufficient security at the facility. Clinton took responsibility for the incident before the report was released, but she was not blamed. Four officials cited in the report have either resigned or been reassigned.
