Abstract		Birds are natural reservoir of influenza viruses. Wild birds and domestic poultry can suffer from avian influenza (flowel plague), showing different signs: decreased egg production, excessive lacrimation, oedema of the head, loss of feathers, diarrhoea, respiratory signs with cyanosis and nervous system disorder. The transmission of avian influenza viruses from birds directly to humans was not known before year 1997. In Hong Kong, during the epidemic caused by highly pathogenic avian influenza virus (HPAI) H5N1 in year 1997, for the first time a low number of human cases were identified infected with the same virus. In following years, more extensive virological surveillance recognised avian influenza viruses (including subtypes not highly pathogenic for birds) in patients with respiratory symptoms and usually epidemiologically linked to diseased birds. At this time, the spread of HPAI H5N1 in the South East Asia generates a certain degree of concern. In spite of high number of poultry farms affected, the confirmed human case are rare. According to WHO data, till now the HPAI H5N1 caused death of 27 people. The appearance of new influenza virus subtype, which is able to cause infection in humans, have to be followed thoughtfully. The measures to restrain the spread of new virus have to be prepared. There is a possibility that the virus will change and begin to spread more efficiently between humans. The surveillance data of influenza in animals and in human have to be combined. The current influenza vaccine does not offer any protection against HPAI H5N1. (Abstract truncated at 2000 characters)
