What are the ways of infection with avian influenza? How to prevent bird flu?

1. The main modes of transmission of avian influenza:

1. The main source of infection: chickens, ducks, etc. infected with avian influenza

2. The main transmission routes: Humans can become infected through direct contact with infected poultry and their feces and secretions. Human-to-human transmission of avian influenza virus has not yet been found.

2. Clinical manifestations of avian influenza in humans:

The early symptoms are very similar to other influenzas, with the main symptoms being high fever (mostly lasting above 39 degrees), cough, sore throat, General discomfort, some patients may have gastrointestinal symptoms, some patients may have unilateral pneumonia on chest X-ray, and in severe cases, multiple organ failure may occur, leading to death.

3. Prevention

1. Wash your hands frequently

Washing hands with soap and running water is more effective.

2. Chicken and eggs must be cooked

Chicken and eggs must be cooked before consumption. Influenza viruses generally cannot survive at 70 degrees Celsius or above. Experts remind: Friends, do not buy poorly prepared poultry food, such as half-cooked white chicken, drunken chicken, half-cooked duck and goose meat. In addition, please go to regular stores and commercial outlets to purchase poultry meat that has undergone strict quarantine, and do not slaughter poultry for consumption by yourself.

3. Pay attention to disease prevention

Because there is currently no effective vaccine, and winter and spring are the periods of high incidence of respiratory diseases, a healthy lifestyle is very important for the occurrence of diseases. Pay attention to physical exercise and ensure that you exercise 2-3 times a week for half an hour each time. You should also ensure adequate sleep.

4. Pay attention to high temperature virus prevention

The avian influenza virus is very sensitive to organic solvents such as ether and acetone, high temperatures and ultraviolet rays. Heating at 60 degrees for 10 minutes, heating at 70 degrees for a few minutes, heating at 100 degrees for 1 minute, direct sunlight for 40 to 48 hours and the use of common household disinfectants can kill the avian influenza virus.

5. Do not take children to poultry markets

The World Health Organization believes that children under 12 years old are currently the most vulnerable to infection! Please do not let children touch or hug poultry, and do not take children to poultry markets.

6. Do not travel to epidemic areas

7. Do not come into contact with live poultry

If you work and live in epidemic areas, please keep in mind: 1) Feces, Secretions are one of the ways of transmission of avian influenza. 2) Remember to wash your hands immediately with soap and running water after coming into contact with poultry. The washing area includes hands, forearms and upper arms. 3) Try to avoid contact with poultry.

8. Don’t take pets lightly

Friends who keep birds should be highly vigilant. Birds are easily infected with the avian influenza virus. Even if you are not in an avian influenza epidemic area, in order to Your family, please note: Pay attention to disinfection when removing bird droppings, ensure ventilation and hygiene in the cage, wash hands promptly after contact with birds, and contact the veterinarian promptly if the bird becomes sick. How to prevent avian influenza when raising chickens

There is no need to protect against avian influenza viruses when raising chickens.

Avian influenza viruses can only infect poultry,

Human influenza viruses can only infect humans,

This is what Chinese researchers experienced fifty years ago

The conclusion drawn from the experiment on the incidence of influenza virus infection is also the natural law of the coexistence of humans and animals.

This conclusion is completely consistent with reality. What are the types of avian influenza?

Avian influenza is the abbreviation of avian influenza. It is an infectious disease caused by a subtype of influenza A virus (also called avian influenza virus). The disease is classified as a Class A infectious disease by the International Office for Animal Epidemics, also known as true chicken plague or European chicken plague. According to different types of pathogens, avian influenza can be divided into three categories: highly pathogenic, low pathogenic and non-pathogenic avian influenza. Non-pathogenic avian influenza does not cause obvious symptoms and only causes infected birds to produce virus antibodies. Low-pathogenic avian influenza can cause mild respiratory symptoms, reduced food intake, reduced egg production, and sporadic deaths in poultry. Highly pathogenic avian influenza is the most serious, with high morbidity and mortality, and infected chickens are often "annihilated." How to prevent and treat avian influenza in schools

Avian influenza is a type of pathogenic influenza that can be transmitted to humans through the respiratory tract. For birds, this kind of virus can be fatal, or it can be said to be just a carrier. Viruses such as H7N9 are found in poultry and wild birds, and they are carried without causing death: many patients have been to wet markets, that is, live poultry markets, which means that this type of virus does not cause the death of poultry quickly, otherwise they will die. If it falls off, it will not enter the live poultry market. What needs to be explained is that people’s individual immunity varies greatly. For some people who are easily infected, such as the elderly, the weak, people with chronic medical conditions and other physical conditions, it is easier for the virus to evade the body’s natural immunity, such as non-specific Immunity (immune cells, macrophages), while infecting human respiratory tract epithelial cells. Different types of viruses can extend into the lungs, bronchial tubes, and upper respiratory tract, and cause correspondingly different damage.

If infection occurs deep in the lungs, it will induce malignant pneumonia and lead to death. Of course, infection in other parts may also cause pneumonia as the condition worsens, but the initial infection site will undoubtedly cause an important gap in the development of the disease. Tamiflu is a treatment drug for influenza viruses, but not a preventive drug. Fortunately, there are currently no influenza viruses that are resistant to Tamiflu, so the drug can still be used for treatment. For prevention, it is divided into two categories: active prevention involves the development of corresponding vaccines, specific vaccines and broad-spectrum vaccines - referring to a type of vaccine that can be immune to multiple viruses at the same time; after a certain proportion of the population is vaccinated, the virus will naturally be blocked. The scope is expanded to provide respite for rescue patients. Another type of prevention comes from the isolation of the crowd, isolating the sick in a timely manner; or isolating risky places to provide space conditions for rescue. Personally speaking, one needs to have knowledge about viral infectious diseases, clearly understand the dangers of viruses, and make personal preparations. Personal protection: washing hands, face, extra protection during haze days, and vaccination are all must-dos. Diary "How to Prevent Bird Flu" 70 words

Strengthen physical exercise, pay attention to nutritional supplements, and ensure adequate sleep and rest to enhance resistance. Minimize contact with poultry, especially sick and dead poultry. In addition, all teachers and students are required to develop good personal hygiene habits, strengthen indoor air circulation, open windows frequently, and ventilate frequently; poultry must be cooked thoroughly before eating; if fever, headache, cough, chest tightness, When you feel general discomfort and other respiratory symptoms, go to the hospital as soon as possible and tell your students the official telephone numbers of Beilun District and Ningbo City.

Bird flu, if you are hit by bird droppings, you may be infected with bird flu! ?

You are so funny, bird flu is not bird flu! You will not be infected if you are hit by bird droppings. Bird flu can only be spread through washing your hands. Are you worried? Go check it out! It is recommended not to go! The upstairs is 100% fake! What types of avian influenza are there? Can they be transmitted to humans?

There are many types of avian influenza, and almost all subtypes are found in birds, except for H17N10, the latest discovery last year, which was found in bats isolated. No virus has been found that can infect humans and be transmitted from person to person. It can be transmitted to humans only accidentally. How do people become infected with avian influenza

Avian influenza viruses are mainly spread through the secretions of poultry and are generally not easy to infect humans. The main way for humans to become infected with avian influenza viruses is through contact infection, and feces is the main way to spread avian influenza. channel. There have been no known cases of infection caused by eating chicken and eggs. Bird flu, which has killed at least 10 people in Vietnam, is mainly spread through poultry feces, not cooked meat.

Personnel engaged in raising, slaughtering, selling, and processing poultry, including other people who may have direct contact with live poultry, are at high risk of contracting avian influenza. Symptoms of chickens infected with avian influenza

The symptoms of avian influenza vary depending on the breed, age, gender, degree of concurrent infections, virus virulence and environmental factors of the infected poultry. The main manifestations are respiratory tract, digestive tract, etc. Abnormalities of the tract, reproductive system, or nervous system.

Common symptoms include: sick chickens are depressed, feed consumption is reduced, and they become thin; hens become more nest-oriented and egg production decreases; Bird flu Is bird flu so terrible? How to prevent it? It is necessary ?

Avian influenza prevention

(1) Strengthen the monitoring of poultry diseases. Once an avian influenza epidemic is discovered, the animal epidemic prevention department will immediately handle it in accordance with relevant regulations. All relevant personnel involved in breeding and handling should take protective measures.

(2) Strengthen monitoring of personnel in close contact with poultry. When influenza-like symptoms occur among these personnel, an epidemiological investigation should be conducted immediately, patient specimens should be collected and sent to designated laboratories for testing to further clarify the pathogen, and corresponding prevention and treatment measures should be taken.

(3) People who come into contact with human avian influenza patients should wear masks, gloves, and isolation gowns. Wash hands after contact.

(4) It is necessary to strengthen the management of test specimens and laboratory avian influenza virus strains, strictly implement operating regulations, and prevent hospital infections and laboratory infections and spread.

(5) Pay attention to food hygiene, do not drink raw water, do not eat undercooked meat, eggs and other foods; wash your hands frequently and develop good personal hygiene habits.

(6) Drug prevention: If necessary, anti-influenza virus drugs can be tried for close contacts or prevention based on syndrome differentiation of traditional Chinese medicine.

(7) Do not travel to epidemic areas.

(8) Pay attention to high temperature virus prevention.
