This is further sub-grouped according to the characteristics of their membrane glycoprotein heamagglutinin (HA) and neauramase (Na) influenza A (H5 N1) variations in these allow influenza to attack repeatedly.

           The present virus now prevailing is influenza type A (H5 N1). This occurs mainly in birds and is highly contagious.

  • Outbreaks of H5 N1 were on going in a number of countries.
  • The H5 N1 influenza a virus subtype that occur mainly in birds and is highly contagious.
  • Mostly cases are those that are in direct contact or close contact with poultry. There are chances that one day H5 N1 will infect human and spread very easily from one person to another. As it does not affect human, there will be hardly any immunity against it if it attacks.

Experts from all over the world are watching the H5 N1 virus in Asia and Europe; that it may begin to spread more easily from person to person
