Influenza A H7 virus is usually a group of influenza viruses that spread in birds. Influenza A virus (H7N9) belongs to a subpopulation of the H7 virus family. Although occasionally there are reports of certain H7 viruses (H7N2, H7N3, H7N7) infecting humans, there have been no reports of human infection with H7N9 viruses until recently. Reported cases of human infection.
Bird flu viruses are generally sensitive to heat and have strong resistance to low temperatures. They can be inactivated by heating at 65°C for 30 minutes or boiling (100°C) for more than 2 minutes. The virus can live for 1 week in the lower temperature feces and 1 month in the water at 4°C. In addition to being transmitted through the respiratory tract, infections such as infected poultry secretions or excretions can also be infected. Direct contact with the virus can also be infected. Although the origin and mode of transmission of the infection cannot be determined, the following measures are effective measures to prevent infection:
1. Do not contact, eat disease (dead) poultry, livestock, do not buy fresh, live, frozen poultry and livestock products without quarantine certificates.
2. Raw poultry, meat, and eggs must be cooked thoroughly.
3. In the process of food processing and consumption, it is imperative to separate raw and cooked foods to avoid cross-contamination. The chopping boards, knives, and containers used to handle raw poultry and livestock meat cannot be used for cooked food;
4. To maintain good personal hygiene habits, do not drink raw water.
White cut chicken does not eat or eat less
Poultry cooked and thoroughly cooked does not usually cause the spread of the bird flu virus. However, if sick poultry are not cooked and cooked, the virus is likely to enter the body. The processing of white-cut chicken may not be fully cooked, so that if this chicken is infected with the bird flu virus “beforeâ€, during the cooking process, the virus may not be completely killed and it may enter the body. However, if it survives, whether it will pass through the digestive tract into human tissues and how the virus works in the human body, these mechanisms are still unclear. In this case, you should try to eat some cooked, cooked foods, eat less or not eat white cut chickens.
Chicken chicken powder is safe to eat
The bird flu virus is not very resistant to the outside world. It is heated at 56°C for 30 minutes, heated at 60°C for 10 minutes, heated at 70°C for several minutes, exposed to direct sunlight for 40-48 hours, and commonly used disinfectants can inactivate the virus. Chicken chicken, chicken and other chicken-related products are made of chicken as raw materials, processing through a special process, in general, high temperature is an essential process. It is safe to eat chicken-related products such as chicken powder and chicken essence from a regular manufacturer (with a health permit). High-risk groups take vitamin C
High-risk groups of bird flu include people who are often in close contact with live birds, such as breeders and slaughter workers, as well as elderly, children, and chronically ill patients with poor resistance, especially children under 12 years of age. Breeders and slaughter workers should wear protective clothing and protective equipment in the workplace and thoroughly sterilize them before and after work; elderly people, children, and chronic disease patients should avoid going to places where live poultry and other live poultry are more, and pay attention to ingesting some more rich foods. Vitamin C and other immune-enhancing foods and drugs are properly exercised to increase the body's resistance to the virus.
