At the workshop to evaluate the performance of the national influenza surveillance system, yesterday, Dr. Nguyen Tran Hien, Director of the National Institute of Hygiene and Epidemiology, said that the mortality rate due to A (H5N1) flu in Vietnam is very high. In 2009, this rate is 100%.

The reason is that monitoring of detection of avian influenza in animals is still poor, patients are slow to go to medical facilities after the disease starts. At the lower level, the diagnosis is not timely, leading to the delay in transferring patients to higher levels. Most of these cases are dispersed, separate in different provinces and close contact with sick poultry.

Dr. Tran Ngoc Huu, Ho Chi Minh City Pasteur Institute, said that the coordination between veterinary and health is not good. In principle, bird flu appears first, then appears on humans. However, the recent fact must detect flu in the first and then investigate the epidemic to detect influenza in poultry. According to Huu, there should be more active coordination to prevent pandemics.

The situation of influenza A (H1N1) is still complicated, spreading the community. Monitoring results at 15 national key points show that the rate of H1N1 flu cases is still high. The number of positive cases for flu types on the total number of tests is 23% - 60%, of which 80% - 90% are influenza A (H1N1). After more than 5 months from the first detection of the infection in Vietnam, the epidemic has spread to most localities, with 96.5% of cases detected as H1N1.
