Abstract

Avian influenza (AI) is a viral infection found in domestic poultry and a wide range of other birds. There are many AI virus strains, which are usually classified into two categories, low pathogenic avian influenza (LPAI), which typically cause few clinical signs in poultry and highly pathogenic avian influenza (HPAI), which can cause severe clinical signs with high mortality rate. Wild birds, waterfowl and shorebirds are often asymptomatic carriers.AI has captured the attention of the international community over the years, because outbreaks will leads to severe impact on both livelihoods and international trade in many countries. Continuous monitoring and controlling AI at its source are important factor which decrease the virus load in susceptible avian species and environment. Implementation of biosecurity measures, in line with OIE international standards, is key factor which secures the production sector, trade, food security, livelihoods of farmers and to limit the risk of human infection with AI.
