...authors of the Science paper based their findings on early data from the H1N1 outbreak, estimating that about 23,000 people had been infected in Mexico by late April, with a fatality rate of about 0.4%. Those numbers come with a wide margin for error on either side, and there are still holes in the epidemiology that need to be filled, but the consensus is that the WHO's handling of H1N1 was reasonable. "Our research indicates that the WHO was justified in its actions in the early days," says Christophe Fraser, an epidemiologist at Imperial College and the lead...
...clear why that is. It could be that older people are more likely to have contracted a virus similar to H1N1 in the past, which might give them some immunity. Or it may be that young people simply encountered H1N1 more often in the early days of the outbreak. The only thing that's clear is that young people are contracting it and they are getting sick. In the small Mexican town of La Gloria, where the virus appears to have originated in early February, H1N1 infected over 61% of the under-15-year-olds in the community. That...
...studies published recently in the New England Journal of Medicine indicate that older people in the U.S. also appear to have escaped the virus - just 5% of U.S. patients with confirmed cases of H1N1 are 51 or older. Still, since health officials have so far focused mostly on outbreaks in schools, it's possible they are simply missing older cases. "This is an evolving outbreak and we're still learning how this virus works," said Fatima Dawood, a CDC epidemiologist...
...program in Mexico run by the David Rockefeller Center for Latin American Studies. In addition, there are half a dozen undergraduates researching or traveling in the country on Harvard grants. Students may still opt out of attending university-sponsored travels to Mexico if they are personally concerned about the outbreak. “We understand that one’s health is a very personal thing. If a student decides not to go to Mexico, we will sit down with him or her and figure things out on a case by case basis,” said Christopher...
...though more people have been taking action to protect themselves, according to a Harvard School of Public Health survey released Friday. The survey, conducted by the Harvard Opinion Research Program at HSPH, is the first comprehensive nation-wide survey that polls the reactions, beliefs, level of alarm about the outbreak. Results were announced through the Center for Disease Control, which funds the survey, as part of the CDC’s daily update on swine flu. This is the second HSPH survey on Americans’ response to the outbreak. The first was released on May 1—just...
