John Roach in his article "Summer to kill Swine Flu in U.S. and Mexico" elucidates why the swine flu cannot survive for a long period of time. Roach claims that the hot ans humid days of summer will put an end to the swine flu. Most types of influenza have a lower rate of transmission in the summer. " Flu viruses survive longer and transmit more easily during low absolute humidity, a condition commonly associated with cold, dry, winter weather." The flu can nearly disappear in the summer unless the virus has built a resistance to the weather since the outbreak was in the hot and humid season in Mexico. All what is going to happen really depends on the biology of the virus so we really cannot do anything but wait and watch what will happen with the swine flu.
Discussion Question:
Clarification: Why can't the influenza virus survive in the summer?
Application: What would happen if the Swine Flu survives during the summer? What precautions would people have to take?
