Experts Against H7N9 Avian Influenza: Three Lines of Defense

The threat of H7N9 avian influenza still exists in Chinese mainland. Li Shuhui, director of Animal Health Laboratory of Agriculture Committee, recently visited Shanghai. She said that the virus detected by poultry in Chinese mainland is not a sample sent by poultry farms, so local people think that as long as cooked food is prepared and contact with birds is avoided, there is no need to panic about the epidemic. She stressed that chicken farms in Taiwan Province Province have never detected H7 antibodies, that is, they have never been infected. Don't worry too much at this stage. As long as the three lines of defense are implemented in the future, bird flu will not be so easily transmitted to people.

She said that the virus detected by poultry in Chinese mainland did not come from poultry farms, and stressed that chickens and ducks in Taiwan Province Province are safe at present.

Li Shuhui said that H7N9 is a low pathogenic avian influenza virus, so there will be no clinical symptoms and no large number of deaths after poultry infection. At present, the mainland is also monitoring and environmental sampling of human infection cases near live poultry markets and farms. At present, 39 positive samples of H7N9 subtype avian influenza virus have been found in the sampling point * * *, but none of them came from poultry farms.

Li Shuhui pointed out that in fact, when he visited the market, the live poultry market was closed, so there were no more live chickens for sale. Although Shanghai has the largest cumulative number of cases, she pointed out that Shanghainese are "calm" about epidemic prevention and think that eggs and chicken should be cooked, so there is no need to worry about infection after eating them.

She pointed out that the risk of eating eggs and chicken in Taiwan Province Province is actually smaller than that in mainland China, because chicken farms in Taiwan Province Province have never detected H7 antibodies, that is, they have never been infected with this virus; At present, H7N9 virus has not been detected in ducks, so there is no need to panic when eating chickens and ducks in Taiwan Province Province at this stage.

Taiwan Province Province has three lines of defense against bird flu.

How to prevent the virus risk brought by migratory birds in the future? Li Shuhui pointed out that there are three firewalls in Taiwan Province province. The first is the monitoring of migratory birds, especially this year. Once the bird flu virus is isolated from the hind bird, an alarm will be issued, requiring farmers to enclose the feed trough so that the hind bird can avoid touching ducks susceptible to the virus.

The second line of defense is to keep ducks and chickens away, because H7N9 avian influenza has low pathogenicity and low toxicity to poultry, chickens and ducks. Avoiding contact with chickens is to avoid repeated gene exchange in chickens. The third line of defense is that people should not be in close contact with chickens. As for poultry farmers, they must manage themselves. She believes that if such measures can be implemented, this new epidemic can be dealt with in the future.

Go to the mainland to avoid the traditional market with live birds.

The Central Epidemic Command Center emphasizes that people who travel or do business in the Mainland should maintain hygienic habits such as washing their hands frequently, avoid contact with birds, and cook poultry meat and eggs carefully. It also puts forward a new appeal of "avoiding the traditional market with live birds".
