Vietnam: Genome sequenced strains of bird flu virus in Vietnam

21/03/2012

Avian influenza is currently a hot issue concerns the whole society by disease situation is very complex events and unpredictable. Before this situation, the Veterinary Faculty of Agriculture University of Hanoi was quickly involved in the monitoring, diagnosis, study the transformation of avian influenza virus, contributing to the prevention of disease risk this coverage.
From this year, bird flu has hit back and appeared in 28 communes of 21 districts of 11 provinces: Hai Phong and Thai Nguyen, Hai Duong, Ha Nam, Bac Giang, Quang Tri, Thanh Hoa, Soc Trang and Kien Giang, Ha Tinh, Quang Nam, an increase over the same period in 2011. As of February 18, the total number of birds infected, death and destruction is 51.983 children in which nearly 90% duck, is the second most dangerous cases of illness and death in humans in Kien Giang and Soc Trang. In our country, the strain of influenza, "Branch 1" (C1) occurs mainly in 2003 - 2010. Since 2007 virus appears more "branch 2" is C2.3.4. By the year 2009-2011, which appears more and not stop C2.3.2 branch, this branch further into sub-branch changes A and B in which the strong virulence of group A than group B. The emergence of new strains of flu virus makes the virus more virulent strength with wet weather conditions, make the disease spread faster speeds and more dangerous flu strain appeared before.
Before this situation, the Veterinary Faculty of Agriculture University of Hanoi task force formed by the TS. Nguyen Ba Hien, Dr. Nguyen Huu Nam and other medical staff were actively involved in the monitoring, diagnosis, study the transformation of avian influenza virus. By Real time PCR technique, the central laboratory of Veterinary Medicine by Dr.. Nguyen Thi Lan charge has successfully deciphered the genetic sequences of 19 strains of avian influenza virus is circulating in some provinces, help to prevent spread of animal diseases in poultry health protection for people and pets .
