Causes of Pandemic (H1N1) 2009 Influenza
There are two main types of influenza virus-type A and type B. The 2009 outbreak is due to a new mixture of different kinds of influenza A. This strain passes from human to human, so it may spread rapidly.
The pandemic H1N1 flu spreads in the same way as the Seasonal Influenza:
- By breathing in droplets after an infected person coughs or sneezes
- By touching a contaminated surface (The virus can survive on surfaces and infect a person for 2-8 hours after being exposed to the surface.) and then touching your eyes, nose, or mouth
