Life Cycle Of Influenza A


Influenza , commonly known as " the flu ", is an infectious disease caused by an influenza virus. Frequent hand washing reduces the risk of viral spread, as does wearing a surgical mask. Influenza spreads around the world in yearly outbreaks , resulting in about three to five million cases of severe illness and about , to , deaths. Symptoms of influenza can start quite suddenly three to four days after infection. It can be difficult to distinguish between the common cold and influenza in the early stages of these infections. Diarrhea is not usually a symptom of influenza in adults, [20] although it has been seen in some human cases of the H5N1 "bird flu" [33] and can be a symptom in children. Occasionally, influenza can cause severe illness including primary viral pneumonia or secondary bacterial pneumonia. INFLUENZA.
