Avian Influenza Disease Emergency: issue No. 18 (14/072004)
1. Current Status Avian influenza in Asian countries far from overVirus still circulating in the regionProper use of quality vaccines an optionBiosecurity a must. New outbreaks of the AI virus H5N1 in China, Thailand and Viet Nam confirm that viral activity is still present in the region. In the aftermath of the major outbreaks between January and March, affected countries succeeded greatly in bringing the disease under control but more may be required. The recent sur ge of new outbreaks (or improved surveillance) clearly demonstrate that the virus continues to circulate in parts of the region which are likely to continue in future, posing a continuing threat to animal and human health and thwarting restocking and rehabilitation initiatives for the poultry sector. It is very encouraging, however, that governments have reacted immediately to recent outbreaks and have officially informed international organizations in a timely manner. Key elements of a successf ul control strategy are: continued surveillance operations throughout all poultry production systems, strengthened biosecurity of commercial or local enterprises and a rapid response to outbreaks including stamping-out in affected areas, with proper disinfection, restriction of movement of animals and goods, and continuous public awareness campaigns. Targeted and strictly monitored vaccination using a quality assured vaccine remains a complementary option. Restocking should only be resumed if ad equate preventive measures are put in place to preclude re-infection. Through several national and regional projects, FAO is closely monitoring the situation and is assisting countries in further improving surveillance and disease reporting.
