Since early November, cases of H1N1 have continued to decline nationwide, and scientists keeping track of the numbers say that as pandemics go, 2009 H1N1 may turn out to be a mild one - at least for the time being...
...been waning for the third week in a row, health officials warn that there are still four to five months left in the official influenza season, plenty of time for the virus to make its rounds and find new hosts. "The story of pandemics, and the story of H1N1 in general, is the story of persistent uncertainty where we never quite know what we are going to get or when," says Dr. Irwin Redlener, director of the National Center for Disaster Preparedness at the Columbia University Mailman School of Public Health...
...severe the current H1N1 pandemic seems depends on what you use as a measuring stick. Compared with previous pandemics, like the 1918 Spanish flu, which killed 20 million people and infected up to 40% of the world's population, or even the far less deadly 1957 and 1968 bouts with a strain of H1N1 influenza similar to the 2009 strain, things don't seem as bad this time around. Fewer people are getting severely ill when infected, and fewer have died or required hospitalization from the flu than in previous pandemics. (See what you need to know about the H1N1...
Marc Lipsitch, an epidemiologist at the Harvard School of Public Health, and his colleagues studied the course of the 2009 H1N1 pandemic last spring in two cities - New York and Minneapolis - and determined that 0.048% of people who developed symptoms of H1N1 died, and 1.44% required hospitalization. Based on that data, published in PLoS Medicine, Lipsitch anticipates far fewer deaths from 2009 H1N1 than was initially believed. By the end of the flu season in the spring of 2010, Lipsitch predicts, anywhere from 6,000 to 45,000 people will have died from H1N1 in the U.S., with the number...
...H1N1 Vaccine With the world already grappling with a pandemic of 2009 H1N1 influenza, no treatment was more hotly anticipated or more in demand in the U.S. (and the rest of the northern hemisphere) than the new H1N1 vaccine when flu season officially kicked off in the fall. Despite the fact that the vaccine had proved effective in trials with one dose - rather than two, as researchers had originally expected - the vaccine supply from U.S. manufacturers still couldn't keep pace with demand in the first weeks of October, when the first million or so shots rolled off production lines...
