The article below talks about the new strain, how the poultry are healthy, show no signs of disease, and how the vaccine has been reduced in effectiveness by 35-40%. It also mentions that in Ha Tinh it has monitored more than 260 people that have had contact with poultry. I just added the province of Bac Kan, as having poultry infected with H5N1. Post below this one.
Since early this year, the country has discovered four cases of influenza A/H5N1, including 2 deaths.
According to Nguyen Van Binh, Director of Preventive Health (MOH), the bird flu recurrence in some provinces such as Quang Binh and Ha Tinh and Hai Duong, Hai Phong and Ninh Binh is an increased risk of spread of influenza A/H5N1 in humans.

Recently notified the Department of Animal Health (Ministry of Agriculture and Rural Development) on the results of genetic analysis showed that explanation appears branch new bird flu virus in North, Central and Western Highlands. Time, the protective effect of vaccine before the new strain of bird flu this decrease, only 35-40%. This makes the risk of A/H5N1 flu in humans are higher.
Nguyen Tran Hien, Director of the Institute of Hygiene and Epidemiology, said direct contact with infected birds is the main route of transmission. The fact that time, most cases of influenza A/H5N1 were related to breeding, slaughtering and eating poultry.
But today is the most difficult job there is no circulating virus clinical signs in poultry flocks healthy, why people do not know how sick poultry as a precaution. This is also the most difficult to control pathogens and potential risk of transmission from poultry to humans, in which the elderly and children are the easiest most viral infections due to less resistance.
Besides, the new strain found in poultry excreta of a highly contagious disease spread through the air, dust and respiratory problems. Nguyen Tran Hien said: "First priority must be to prevent the spread of epidemics in poultry. Besides, the phenomenon must be detected early bird mortality and notify local authorities to promptly prevent epidemic. Absolutely not slaughter and use sick poultry. Health sector must work closely with the veterinary services, strengthening health education and propaganda for people to better understand the risk of transmission and outbreak of influenza in poultry and humans, warning people to enhance more measures of personal hygiene, food hygiene to prevent disease transmission from poultry to humans. "
Department of Preventive Medicine recommend the local health sector have bird flu as Quang Binh, Hai Duong, Ninh Binh and Ha Tinh, Quang Ninh quickly implement measures to prevent, not to bird flu chance to spread to humans, especially propaganda for people to understand the mechanism of transmission of disease. This time, though not yet detected any cases of new influenza A/H5N1 but people should not be subjective, by two A/H5N1 flu deaths were due earlier this year after nearly two years neglected no cases New.
