Many thousands of Americans could die over the following 2 years if the vaccine and other control measures for the new H1N1 influenza are not effective, and, at the epidemic's peak, as much as 40% of the workforce may be influenced, according to new guesstimates from the Centers for Disease Control and Prevention. That is albeit a worst-case eventuality the Fed. Agency explains it doesn't expect to happen. The amount of potential deaths is far higher than that generally seen in seasonal influenza, which kills a computed 36,000 Americans a year, and is even higher than the state's latest epidemic.
The 1957 epidemic of Asian influenza killed seventy thousand. The vaccine the CDC is relying on isn't expected to be available before the end of September, too late to immunize kids prior to the start of school, where the vicinity of youngsters is anticipated to speed up transmission of the pathogen. But testing of the vaccine has already begun at some sites, and authorities have no reason to believe it will fail as the technology for influenza vaccines has been completely demonstrated. Rather, the questions have been about how long it will take to supply a new vaccine and how many doses should be available.
Twenty states are now reporting widespread or regional flu activity, with the H1N1 virus predominating, according to Dr. Anne Schuchat, director of the CDC's National Center for Immunization and Respiratory Diseases. "That's very unusual at this time of year," she said. "It's a testament to how susceptible people are to the virus."
In cases the agency has analyzed it's been unable to approve such reports. The agency endorses the drug be administered only to infected patients and as a preventative measure to high-risk folks who are in contact with influenza patients.
To date, only 5 cases of Tamiflu-resistant viruses have been noted internationally and there's no proof that such viruses have been spread from person to person, she announced. But almost all of the strains of seasonal influenza that are now circulating are impervious to the drug and the genes for such resistance could be really simply broadcast to the new pathogen.
According to the most recent figures posted, the U.S. has so far seen 43,771 laboratory-confirmed cases of H1N1, and 302 deaths, "but that is just the tip of the iceberg," Schuchat said. More than a month ago, the agency estimated that more than 1 million Americans had been infected, but that estimate has not been updated.
Schuchat observed this spring, 6% to 8% of the people in several US communities were infected by the pathogen "in a season when transmission conditions were not that great.".
Deaths caused by H1N1 flu over the two-year period could range from 90,000 to several hundred thousand, depending on the efficacy of the swine flu vaccine, officials project.
With the longer winter season coming, "we think it will reach 2 to 3 times that number." Typically, ten percent to 15% of folk in a community are infected with seasonal influenza. And with closures due to outbreaks, as well as the requirement for many healthy adults to remain home and look after a spouse or kid with the influenza.
