U.S. study shows why winter is "flu season" - Yahoo! News: (Reuters) -
2008.03.02
Influenza viruses coat themselves in fatty material that hardens and protects them in colder
temperatures -- a finding that could explain why winter is the flu season...This butter-like coating melts in the respiratory tract, allowing the virus to infect cells..."It's only in this liquid phase that the virus is capable of entering a cell to infect it." Experts have long pondered why flu and other respiratory viruses spread more in winter. No one explanation, such as people staying indoors more, or the destructive effect of the sun's radiation in summer, has fully explained it...In warmer outdoor temperatures this protective coating melts, and unless it is inside a living person or animal, the virus perishes..."
Makes one think that if a pandemic hits the northern hemisphere... head south.
