The H5N1 (Bird) flu virus is an influenza A virus subtype that is highly contagious among birds. Rare human infections with the H5N1 (Bird) flu virus have occurred. The majority of confirmed cases have occurred in Asia, Africa, the Pacific, Europe and the Near East. Currently, the United States has no confirmed human H5N1 (Bird) flu infections, but H5N1 (Bird) flu remains a serious concern with the potential to cause a deadly pandemic.

The H1N1 (Swine) flu virus caused more illness in the 2009-2010 flu season in young people and pregnant women than is usual for prior flu seasons. Like seasonal flu, illness in people with H1N1 can vary from mild to severe.

Difference between H1N1 and H5N1

  • The symptoms of bird flu can be the result of tranmission virus from one person to another person. It can be transmitted by saliva, cough, blood, needles, sexual contact and many more.

  • In this video describes the symptoms of swine flu and warning signs to look for that indicate the need for urgent medical attention.

  • The H5N1 is commonly known as Bird flu virus that is highly contagious among birds while the H1N1 is commonly known as Swine flu virus or respiratory disease of pigs.

  • Treatment

    Neuraminidase inhibitors are a class of drugs that includes zanamivir and oseltamivir, the latter being licensed for prophylaxis treatment in the United Kingdom. Oseltamivir inhibits the influenza virus from spreading inside the user's body. It is marketed by Roche as Tamiflu. This drug has become a focus for some governments and organizations trying to be seen as making preparations for a possible H5N1 pandemic. In August 2005, Roche agreed to donate three million courses of Tamiflu to the World Health Organization, to be deployed by the WHO to contain a pandemic in its region of origin. Although Tamiflu is patented, international law gives governments wide freedom to issue compulsory licenses for life-saving drugs.

    A second class of drugs, which include amantadine and rimantadine, target the M2 protein, but are ineffective against H5N1. Unlike zanamivir and oseltamivir, these drugs are inexpensive and widely available and the WHO had initially planned to use them in efforts to combat an H5N1 pandemic. However, the potential of these drugs was considerably lessened when it was discovered that farmers in China have been administering amantadine to poultry with government encouragement and support since the early 1990s, against international livestock regulations; the result has been that the strain of the virus now circulating in South East Asia is largely resistant to these medications and hence significantly more dangerous to humans.
