H1N1 – We should all be involved

The unpredictability of the H1N1 virus makes it imperative that all individuals play their part to control the transmission of the disease. 

THE only predictable feature about the influenza virus is its unpredictability. The virus mutates often. Minor mutations (antigenic drift) are frequent and cause repeated outbreaks. Major mutations (antigenic shift) are rare and are due to re-assortment of genetic material from different viral sub-types. When they occur pandemics result, causing many deaths.
