FDA: New rules will make food safer


WASHINGTON (AP) — The Food and Drug Administration says its new guidelines would make the food Americans eat safer and help prevent the kinds of foodborne disease outbreaks that sicken or kill thousands of consumers each year.


The rules, the most sweeping food safety guidelines in decades, would require farmers to take new precautions against contamination, to include making sure workers' hands are washed, irrigation water is clean, and that animals stay out of fields. Food manufacturers will have to submit food safety plans to the government to show they are keeping their operations clean.


The long-overdue regulations could cost businesses close to half a billion dollars a year to implement, but are expected to reduce the estimated 3,000 deaths a year from foodborne illness. The new guidelines were announced Friday.


Just since last summer, outbreaks of listeria in cheese and salmonella in peanut butter, mangoes and cantaloupe have been linked to more than 400 illnesses and as many as seven deaths, according to the federal Centers for Disease Control and Prevention. The actual number of those sickened is likely much higher.


Many responsible food companies and farmers are already following the steps that the FDA would now require them to take. But officials say the requirements could have saved lives and prevented illnesses in several of the large-scale outbreaks that have hit the country in recent years.


In a 2011 outbreak of listeria in cantaloupe that claimed 33 lives, for example, FDA inspectors found pools of dirty water on the floor and old, dirty processing equipment at Jensen Farms in Colorado where the cantaloupes were grown. In a peanut butter outbreak this year linked to 42 salmonella illnesses, inspectors found samples of salmonella throughout Sunland Inc.'s peanut processing plant in New Mexico and multiple obvious safety problems, such as birds flying over uncovered trailers of peanuts and employees not washing their hands.


Under the new rules, companies would have to lay out plans for preventing those sorts of problems, monitor their own progress and explain to the FDA how they would correct them.


"The rules go very directly to preventing the types of outbreaks we have seen," said Michael Taylor, FDA's deputy commissioner for foods.


The FDA estimates the new rules could prevent almost 2 million illnesses annually, but it could be several years before the rules are actually preventing outbreaks. Taylor said it could take the agency another year to craft the rules after a four-month comment period, and farms would have at least two years to comply — meaning the farm rules are at least three years away from taking effect. Smaller farms would have even longer to comply.


The new rules, which come exactly two years to the day President Barack Obama's signed food safety legislation passed by Congress, were already delayed. The 2011 law required the agency to propose a first installment of the rules a year ago, but the Obama administration held them until after the election. Food safety advocates sued the administration to win their release.


The produce rule would mark the first time the FDA has had real authority to regulate food on farms. In an effort to stave off protests from farmers, the farm rules are tailored to apply only to certain fruits and vegetables that pose the greatest risk, like berries, melons, leafy greens and other foods that are usually eaten raw. A farm that produces green beans that will be canned and cooked, for example, would not be regulated.


Such flexibility, along with the growing realization that outbreaks are bad for business, has brought the produce industry and much of the rest of the food industry on board as Congress and FDA has worked to make food safer.


In a statement Friday, Pamela Bailey, president of the Grocery Manufacturers Association, which represents the country's biggest food companies, said the food safety law "can serve as a role model for what can be achieved when the private and public sectors work together to achieve a common goal."


The new rules could cost large farms $30,000 a year, according to the FDA. The agency did not break down the costs for individual processing plants, but said the rules could cost manufacturers up to $475 million annually.


FDA Commissioner Margaret Hamburg said the success of the rules will also depend on how much money Congress gives the chronically underfunded agency to put them in place. "Resources remain an ongoing concern," she said.


The farm and manufacturing rules are only one part of the food safety law. The bill also authorized more surprise inspections by the FDA and gave the agency additional powers to shut down food facilities. In addition, the law required stricter standards on imported foods. The agency said it will soon propose other overdue rules to ensure that importers verify overseas food is safe and to improve food safety audits overseas.


Food safety advocates frustrated over the last year as the rules stalled praised the proposed action.


"The new law should transform the FDA from an agency that tracks down outbreaks after the fact, to an agency focused on preventing food contamination in the first place," said Caroline Smith DeWaal of the Center for Science in the Public Interest.

S&P 500 finishes at 5-year high on economic data

NEW YORK (Reuters) - The benchmark Standard & Poor's 500 index ended at a five-year high on Friday, lifted by reports showing employers kept up a steady pace of hiring workers and the vast services sector expanded at a brisk rate.


The gains on the S&P 500 pushed the index to its highest close since December 2007 and its biggest weekly gain since December 2011.


Most of the gains came early in the holiday-shortened week, including the largest one-day rise for the index in more than a year on Wednesday after politicians struck a deal to avert the "fiscal cliff."


The Dow Jones industrial average <.dji> gained 43.85 points, or 0.33 percent, to 13,435.21. The Standard & Poor's 500 Index <.spx> rose 7.10 points, or 0.49 percent, to 1,466.47. The Nasdaq Composite Index <.ixic> edged up 1.09 points, or 0.04 percent, to 3,101.66.


For the week, the S&P gained 4.6 percent, the Dow rose 3.8 percent and the Nasdaq jumped 4.8 percent to post their largest weekly percentage gains in more than a year.


The CBOE Volatility index <.vix>, a measure of investor anxiety, dropped for a fourth straight session, giving the index a weekly decline of nearly 40 percent, its biggest weekly fall ever. The close of 13.83 on the VIX marks its lowest level since August.


In Friday's economic reports, the Labor Department said non-farm payrolls grew by 155,000 jobs last month, slightly below November's level. Gains were distributed broadly throughout the economy, from manufacturing and construction to healthcare.


Also serving to boost equities was data from the Institute for Supply Management showing U.S. service sector activity expanding the most in 10 months.


With the S&P 500 index at a five-year closing high, analysts said any gains above the index's intraday high near 1,475 in September may be harder to come by.


"We are getting to a point where we need a strong catalyst, which could be earnings, it could be three months of good economic data, it could be a variety of things," said Adam Thurgood, managing director at HighTower Advisors in Las Vegas, Nevada.


"What is going on right now is this conflicting view of fundamentals look pretty good and improving, and then you've got these negative tail risks that could blow everything up," Thurgood said.


He referred to "a fiscal superstorm brewing" of issues still left unresolved in Washington, including tough federal budget cuts and the need to raise the government's debt ceiling all within a couple of months.


The rise in payrolls shown by the jobs data did not make a dent in the U.S. unemployment rate still at 7.8 percent.


A Reuters poll on Friday of economists at Wall Street's top financial institutions showed that most expect the Fed in 2013 to end the program with which it bought Treasury debt in an effort to stimulate the economy.


A drop in Apple Inc shares of 2.6 percent to $528.36 kept pressure on the Nasdaq.


Adding to concerns about Apple's ability to produce more innovative products, rival Samsung Electronics Co Ltd is expected to widen its lead over Apple in global smartphone sales this year with growth of 35 percent. Market researcher Strategy Analytics said Samsung had a broad product lineup.


Eli Lilly and Co was among the biggest boost's to the S&P, up 3.7 percent to $51.56 after the pharmaceuticals maker said it expects its 2013 earnings to increase to $3.75 to $3.90 per share, excluding items, from $3.30 to $3.40 per share in 2012.


Fellow drugmaker Johnson & Johnson rose 1.2 percent to $71.55 after Deutsche Bank upgraded the Dow component to a "Buy" from a "Hold" rating. The NYSEArca pharmaceutical index <.drg> climbed 0.6 percent.


Shares of Mosaic Co gained 3.3 percent to $58.62. Excluding items, the fertilizer producer's quarterly earnings beat analysts' expectations, according to Thomson Reuters I/B/E/S.


Volume was modest with about 6.07 billion shares traded on the New York Stock Exchange, NYSE MKT and Nasdaq, slightly below the 2012 daily average of 6.42 billion.


Advancing stocks outnumbered declining ones on the NYSE by 2,287 to 701, while on the Nasdaq, advancers beat decliners 1,599 to 866.

News Analysis: Debt Deal Fails to Allay Fears on U.S. Global Power





WASHINGTON — Two years ago the departing chairman of the Joint Chiefs of Staff, Adm. Mike Mullen, declared that “the most significant threat to our national security is our debt.” After a decade in which the nation had chased Al Qaeda and invaded Iraq, Admiral Mullen was saying, in essence, that the biggest enemy was us.

Some analysts worry that the United States will not maintain influence in places like Myanmar.







Now that Congress and President Obama have slipped past the latest budget deadline with a bill that does little to address the country’s long-term debt issues — and by some measures might worsen them — the worries of the national security establishment have been reignited. Most pointedly, military and diplomatic experts wonder whether the United States is at risk of squandering its global influence.


“There’s a sense that we’ve been playing roulette with our position, and this deal does nothing to stop that,” Richard N. Haass, the president of Council on Foreign Relations, said in an interview. His coming book, “Foreign Policy Begins at Home,” is part of a wave of recent literature arguing that America’s reduced global ambitions are linked to its status as a debtor nation.


Vali Nasr, who will soon publish “The Dispensable Nation,” argues that the debt, among other economic woes, has allowed Mr. Obama and other Democrats to justify a retreat from global engagement. “It’s made it far easier to say ‘We can’t do more,’ ” said Mr. Nasr, the dean of the School of Advanced International Studies at Johns Hopkins University. “And without addressing the debt issues, it will be easier to make that argument for years to come.”


A departing senior diplomat at the State Department who requested anonymity, ruminating on the outcome of the confrontation on the fiscal crisis, said that the failure to attack the long-term debt issues would become another reason “to turn our backs on the Middle East and trim our sails on the new focus on Asia.”


That is the theme that the Chinese — who have an interest in portraying the United States as a declining power unable to manage its economy — are already promoting. “The politicians have chosen to kick the can down the road,” the state-run Xinhua news agency said in a commentary on Wednesday. “The can will never disappear,” it continued, warning that the United States was falling “into an abyss you can never come out of.”


Most evidence suggests that the country’s debt is not an immediate crisis. The deficit is expected to shrink somewhat in coming years, and even after the United States lost its AAA bond rating, foreigners have remained willing to lend the country money at very low interest rates. That is a sign of confidence in the American economy and a recognition that Europe and Asia have problems of their own.


But the aging of the population and the growth of health costs will most likely cause the deficit to grow rapidly in coming decades, meaning that the most difficult choices about taxes and spending are still ahead. Absent decisions on those issues, the government will have fewer resources and be more dependent on foreign lenders — increasingly the Chinese.


“Partly it is about resources,” Mr. Haass said, referring to the national security implications of the deficit. “But it is also about reducing your vulnerability to the machinations of currency markets and potentially hostile central bankers” who choose whether to buy American debt.


“When we appear to be dysfunctional, as we have in recent times, it makes it hard to be the model for the democratic, capitalistic model we say we want to be in the world,” he added.


History suggests that the relationship between debt and American power is a complex one, subject to differing interpretations by both economists and historians. The federal debt exceeded 100 percent of the gross domestic product at the end of World War II, but the postwar period nonetheless marked the beginning of America’s superpower status. The debt fell fairly steadily during the cold war, and it was cut to about a third of gross domestic product by the end of the Nixon administration — even as the country retreated into a post-Vietnam War funk.

George Lucas is following the Force – right down the aisle.

The Star Wars director, 68, is engaged to DreamWorks animation chairman Mellody Hobson, a rep for Lucasfilm confirmed to The Hollywood Reporter on Thursday.

Hobson, 43, has been dating Lucas since 2006. This will be her first marriage and Lucas's second; he previously was married to film editor Marcia Lou Griffin. The exes adopted a daughter Amanda before their 1983 divorce. Lucas went on to adopt two more children.

Lucas's fiancée is also a contributor to Good Morning America's financial segments and has received many honors, including a 2002 listing as one of Esquire's "Best and Brightest" in America.

Lucas has made headlines of his own, recently donating to an education foundation much of the $4 billion from his sale of Lucasfilm to Disney.

According to THR, Lucas said at the time, "As I start a new chapter in my life, it is gratifying that I have the opportunity to devote more time and resources to philanthropy."

Indian court to rule on generic drug industry


NEW DELHI (AP) — From Africa's crowded AIDS clinics to the malarial jungles of Southeast Asia, the lives of millions of ill people in the developing world are hanging in the balance ahead of a legal ruling that will determine whether India's drug companies can continue to provide cheap versions of many life-saving medicines.


The case — involving Swiss drug maker Novartis AG's cancer drug Glivec — pits aid groups that argue India plays a vital role as the pharmacy to the poor against drug companies that insist they need strong patents to make drug development profitable. A ruling by India's Supreme Court is expected in early 2013.


"The implications of this case reach far beyond India, and far beyond this particular cancer drug," said Leena Menghaney, from the aid group Doctors Without Borders. "Across the world, there is a heavy dependence on India to supply affordable versions of expensive patented medicines."


With no costs for developing new drugs or conducting expensive trials, India's $26 billion generics industry is able to sell medicine for as little as one-tenth the price of the companies that developed them, making India the second-largest source of medicines distributed by UNICEF in its global programs.


Indian pharmaceutical companies such as Cipla, Cadila Laboratories and Lupin have emerged over the past decade as major sources of generic cancer, malaria, tuberculosis and AIDS drugs for poor countries that can't afford to pay Western prices.


The 6-year-old case that just wrapped up in the Supreme Court revolves around a legal provision in India's 2005 patent law that is aimed at preventing companies from getting fresh patents for making only minor changes to existing medicines — a practice known as "evergreening."


Novartis' argued that a new version of Glivec — marketed in the U.S. as Gleevec — was a significant change from the earlier version because it was more easily absorbed by the body.


India's Patent Controller turned down the application, saying the change was an obvious development, and the new medicine was not sufficiently distinct from the earlier version to warrant a patent extension.


Patient advocacy groups hailed the decision as a blow to "evergreening."


But Western companies argued that India's generic manufacturers were cutting the incentive for major drug makers to invest in research and innovation if they were not going to be able to reap the exclusive profits that patents bring.


"This case is about safeguarding incentives for better medicines so that patients' needs will be met in the future," says Eric Althoff, a Novartis spokesman.


International drug companies have accused India of disregarding intellectual property rights, and have pushed for stronger patent protection that would weaken India's generics industry.


Earlier this year, an Indian manufacturer was allowed to produce a far cheaper version of the kidney and liver cancer treatment sorefinib, manufactured by Bayer Corp.


Bayer was selling the drug for about $5,600 a month. Natco, the Indian company, said its generic version would cost $175 a month, less than 1/30th as much. Natco was ordered to pay 6 percent in royalties to Bayer.


Novartis says the outcome of the new case will not affect the availability of generic versions of Glivec because it is covered by a grandfather clause in India's patent law. Only the more easily absorbed drug would be affected, Althoff said, adding that its own generic business, Sandoz, produces cheap versions of its drugs for millions across the globe.


Public health activists say the question goes beyond Glivec to whether drug companies should get special protection for minor tweaks to medicines that others could easily have uncovered.


"We're looking to the Supreme Court to tell Novartis it won't open the floodgates and allow abusive patenting practices," said Eldred Tellis, of the Sankalp Rehabilitation Centre, a private group working with HIV patients.


The court's decision is expected to be a landmark that will influence future drug accessibility and price across the developing world.


"We're already paying very high prices for some of the new drugs that are patented in India," said Petros Isaakidis, an epidemiologist with Doctors Without Borders. "If Novartis' wins, even older medicines could be subject to patenting again, and it will become much more difficult for us in future to provide medicines to our patients being treated for HIV, hepatitis and drug resistant TB."

Global shares, oil slip on Fed stimulus nerves

LONDON (Reuters) - World shares, oil and copper edged lower on Friday and the dollar rose after U.S. Federal Reserve officials raised concerns about possible side effects of its stimulus program.


Minutes from the Fed's December policy meeting unsettled financial markets as some policymakers raised the longer-term impact of its efforts to simulate the U.S. economy.


The Fed's bond-buying has underpinned appetite for risk, and the comments that raised the possibility it might be less committed to the program than previously thought unnerved investors before U.S. employment data later on Friday.


European shares echoed their Asian peers to open lower. But following a sharp jump on Wednesday after the United States edged back from the "fiscal cliff", they were on track for weekly gains of almost 2.7 percent.


London's FTSE 100 <.ftse>, Paris's CAC-40 <.fchi> and Frankfurt's DAX <.gdaxi> were down between 0.1 and 0.4 percent by 0810 GMT, while the pan-European FTSEurofirst 300 <.fteu3> was down 0.15 percent and the MSCI index of world shares 0.2 percent lower at 345.91.


Euro zone PMI and inflation figures plus the U.S. non-farm payrolls report due through the day will be closely scrutinized by investors looking to assess the health of the global economy.


"The Fed has made it clear that it will keep policy loose until unemployment drops to 6.5 percent or below, so strong jobs data will undoubtedly raise expectations of a more hawkish Fed," analysts at Tradition brokerage said in a note.


The Fed comments gave fresh momentum to the recent slide by low-risk bonds including U.S. and German debt. Bund futures slipped half a point in early trading to 143.07, having already fallen steeply from last week's close of 145.64.


Benchmark U.S. Treasury yields continued their climb, hitting an eight-month high around 1.93 percent in Asia, while 10-year Japanese government bond yields touched a 3-1/2-month high of 0.83 percent.


In the currency market the dollar rose, hitting its highest since July 2010 against the yen at 87.835 while the euro fell to a three-week low of $1.3019. The dollar <.dxy> also touched a six-week high against a basket of major currencies.


The dollar's rise makes dollar-based assets more expensive for non-dollar investors and its rise hit precious metals and oil.


Brent crude shed 0.6 percent to $111.47 while gold fell 1 percent to $1,645, dragging silver down more than 2 percent to $29.48.

Deadly Car Crash? Time to Play the Thai Lottery


Giulio Di Sturco for the International Herald Tribune


GHOSTLY GUIDES Paan Padthong, a fortune teller at the Mae Nak shrine, where Thais go for inspiration in picking lottery numbers.







BANGKOK — At a bend in a busy Bangkok road stands the Tree of 100 Corpses, a shrine to pedestrians who have died in traffic accidents nearby.




People come from all over Thailand to commune with spirits they believe reside in the tree, which is wrapped in golden cloth and surrounded by hundreds of figurines. They also come to find winning lottery numbers.


“I made a wish to the tree and asked that the number pop up in my dream,” said Kriengsak Konart, a motorcycle taxi driver who works in the area. The number 45 came to him in his sleep, he said, and he played a variation of it.


“I won,” he said.


The search for lottery numbers in Thailand can be confusing to outsiders. Many Thais believe that calamity can beget good fortune, and that tragedy may give rise to powerful ghosts who offer guidance on winning numbers. Newspapers report the license plate numbers of cars involved in gruesome accidents. Lottery aficionados note the highway route numbers where accidents took place, tally the casualties and play the numbers. Nothing is seen as too horrible to be a source of good luck, not plane crashes or massacres.


“This is all about superstition,” said Worawit Srianunraksa, the front-page editor of The Daily News here, which, like other Thai newspapers, runs articles packed with numbers that may be useful to lottery players. “People, especially in rural areas, still believe in ghosts and spirits, things that you cannot explain. And they are able to find numbers in any news event.”


Thailand’s favorite topic of conversation is probably food, but a close second is the underground lottery. The game, illegal but tolerated, is played by nearly one-third of a population that marries deeply held superstitions with a proclivity for fun. The search for numbers to play is something close to a national obsession, culminating twice a month in the drawing of plastic balls to decide the winners.


Inspiration does not always come from tragedy. Regular lottery players say that numbers occur to them in dreams or cosmically appear in the bark of trees. They may be gleaned from oddities spotted by villagers and reported in the national news media — a six-legged turtle or a lizard born with an extra appendage, to name two that were reported last month. People play the numbers of the hotel rooms where movie stars stay, the prime minister’s birthday or any numbers related to the royal family.


But many Thais believe that the best numbers come from powerful ghosts, those who have endured terrible pain or suffering.


One of the country’s most famous ghosts is Mae Nak, who is honored at a shrine in southeastern Bangkok next to a Buddhist temple. According to Thai legend, Mae Nak died in childbirth while her husband, a soldier, was away on a military campaign. When he returned, his wife was a ghost soaring through the house.


Paan Padthong, 72, one of many fortune tellers who work near the Mae Nak shrine, said that men and women visited for a variety of reasons. Young men ask the ghost for assistance to avoid being drafted into the military. Women ask for help in conceiving a child. Students seek a cosmic boost on exams.


Mr. Paan said he felt Mae Nak’s presence floating above the shrine. “As we are talking, she hears us,” he said.


Those who go to the shrine for lottery numbers reach into a clay jar and pull out numbered balls. Or they scratch the bark of a tree inside the shrine, looking for digits.


Mr. Paan said they were trying too hard. “If you are someone who possesses good luck, all you have to do is step into the shrine and you will start to see numbers,” he said. “The numbers will just appear.”


The unlucky, on the other hand, need to realize their limitations, he said. “You can scratch the tree all day long, and you’ll never see any numbers.”


In a modern and cosmopolitan city like Bangkok, there are people, of course, who reject superstition. But it speaks to the Thai ethos of live and let live that the nonbelievers do not criticize those who seek supernatural help for their lottery habit. The attitude is captured in a Thai maxim: “If you don’t believe it, don’t insult it.”

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 foredcast, 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.
