According to Xinhua News Agency, Taiyuan, January 17 -, Shanxi Province, one cases of confirmed human infection of highly pathogenic avian influenza cases. 彭某patients, female, 2 years old, on January 7 this year in Hunan incidence.

Prior to this, January 5, Beijing took place one cases of human infection of highly pathogenic avian influenza deaths. January 12, Beijing has been fully lifted 200 celebrity bird flu close contacts of patients with medical observation. At present, Beijing, no animal bird flu report.

Changsha City CDC experts, the avian flu virus is mainly found in poultry and poultry infected with the gastrointestinal, respiratory and poultry in body tissues. Respiratory diseases is now in a good season, how to effectively prevent human infection of highly pathogenic avian influenza?

Avian influenza can infect humans

What is avian influenza? Bird flu is referred to as avian influenza is caused by influenza A virus of avian infectious diseases makes it easy for birds (especially chickens) between the prevalence of, in the past, civil society known as the "plague" . The high mortality rate among infected birds.

What is a human infection of highly pathogenic avian influenza? Bird flu virus can be divided into highly pathogenic and low pathogenic and non-pathogenic three categories. Which is highly pathogenic avian influenza H5 and H7 sub-strains (H5N1 and H7N7 as a representative) diseases.

Highly pathogenic avian influenza in poultry because of its rapid spread and endanger large, high case-fatality rate was World Organization for Animal Health as a Class A animal disease, China to be included in a class of animal disease. Highly pathogenic avian influenza H5N1 is evolving, and its parasitic animals (also known as host) will continue to expand the scope can be infected with tigers, domestic cats and other mammals, the normal domestic ducks carrying the virus and to increase the percentage of emissions, especially in Pigs were detected more often.

Highly pathogenic avian influenza virus can directly infect humans. In 1997, China's Hong Kong region, the highly pathogenic H5N1 type bird flu virus has led to 18 people infected, 6 people were killed and for the first time that highly pathogenic avian influenza can endanger human life.

Combat alert:

What people are infected with avian flu? Avian flu virus can enter the human digestive tract and respiratory tract infection to humans, human avian flu by direct contact with infected poultry and their excreta or direct contact with the avian flu virus can also be infected . Through droplets and contact with respiratory secretions is also the route of transmission. If direct contact with virus, a considerable number of items, such as poultry faeces, feathers and respiratory secretions, blood, etc., can also be broken through the skin and conjunctival infection.

People who will appear after infection symptoms

Experts, real life, of human infection with bird flu high-risk groups is mainly the elderly, children and people in close contact with sick birds.

Mode of transmission of avian flu, there has been direct contact with infected poultry, the virus through indirect contact with the spread of pollutants in two. As the sick organizations, most of them contain high titers of virus, the virus can be as eye, nose and oral secretions and faeces excreted by the virus containing secretions, feces, dead birds of any body of contaminated objects, such as feed, drinking water, sheds, air, cages, feeding and management appliances, transport vehicles, a variety of insects and birds carrying the virus and so on, can the spread. Migratory birds may also be the H5N1 or H5N2 subtype of long-distance spread of the virus.

Of human infection of highly pathogenic avian influenza virus clinical symptoms, early performance is similar to ordinary influenza, such as the performance of fever, runny nose, stuffy nose, cough, pharyngodynia, headache, general malaise and so on, mainly for fever, body temperature mostly in the more than 39 ℃, continuous 1 ~ 7 days, usually 3 to 4 days, some patients may have nausea, abdominal pain, diarrhea, dilute it in water samples and other gastrointestinal symptoms.

In addition to the performance, of human infection of highly pathogenic avian influenza in patients with severe, but also pneumonia, respiratory distress, such as performance, even leading to death. In most cases for the mild, the more after the good, but a small number of patients would cause kidney failure or died of septic shock.

Combat alert:

How to kill the bird flu virus in the environment? Bird flu virus to survive in the external environment are less well off, as long as proper disinfection measures, it is not difficult to kill. Poultry farms commonly used disinfectants, such as aldehydes, chlorine-type agents, oxidizing agents, alkali and so on can kill the virus in the environment.

Influenza vaccine to prevent bird flu, it? To date, has not yet been developed for human use, can effectively prevent bird flu vaccines. Influenza vaccine can not effectively prevent bird flu, but can prevent bird flu and human influenza overlap to form a new influenza virus caused the outbreak, but also help to reduce the risk of influenza caused by the possibility of complications. Therefore, experts recommend long-term elderly and chronic patients flu vaccination.

Everyday people how to guard against avian flu

Day-to-day should be done to prevent bird flu, washing hands frequently, stay away from poultry secretions, contact with birds or bird droppings, it is necessary to pay attention to use of disinfectant and water to clean their hands thoroughly.

Go out on the road to avoid contact with poultry, such as not to go to Aviary, farms, markets or to the park activities; not to feed wild birds such as pigeons or.

Combat alert:

Prevention and control of human infection of highly pathogenic avian influenza key to achieve "four-early principle", refers to the disease to early discovery, early reporting, early quarantine and early treatment.

Early detection, when they or the people around them developed symptoms of fever, cough, shortness of breath, body pain and other symptoms should immediately seek medical treatment. Early reporting, found that people infected with highly pathogenic avian influenza cases or similar cases, timely reporting of local medical institutions, and disease control agencies. As early as the isolation of human infection with highly pathogenic bird flu cases and suspected cases to the timely isolation of close contacts should be carried out in accordance with medical observation or quarantine to prevent the spread of the epidemic. Early treatment, confirmed human infection of highly pathogenic avian influenza patients, should be actively carried out for medical treatment, especially for other chronic diseases to seek early treatment, after treatment and the use of antiviral drugs to support the therapy, symptomatic therapy, the vast majority of patients can be recovered and been discharged.
