Occupational exposure of medical staff is divided into infectious occupational exposure, radioactive occupational exposure and chemical occupational exposure, such as disinfectants and chemicals, such as AIDS occupational exposure, which means that people are infected with HIV during AIDS prevention and other work.
Or the blood and body fluids of AIDS patients pollute the damaged skin and gastrointestinal mucosa, or the skin is stabbed by sharp instruments such as needles contaminated with blood and body fluids containing HIV, all of which may be infected by HIV.
First, the exposure history is a medical term, which generally means that it has appeared in some dangerous and infectious areas or radiation, which is convenient for doctors to check and dispose of.
2. For example, a woman died of bird flu in Urumqi, Xinjiang, and the patient had a history of exposure to the live poultry market before the onset. She often went to the live poultry market when she was alive. Exposure history explains the cause of the disease well.
Thirdly, the common leakage in life is mainly caused by biting or touching the secretions of potential rabies virus infected animals such as dogs and cats.
Four, this kind of vaccination before exposure generally only needs 3 needles, but it needs 5 needles after exposure. There is no essential difference between the two. They all protect the body by injecting vaccines to produce corresponding antibodies, but 5 injections after exposure can enhance immunity, and immunity is stronger, while immunization before exposure is unnecessary.
