Rabies, also known as hydrophobia, is a disease caused by the rabies virus. It can damage the human nervous system and may lead to death in severe cases. Rabies is not incurable, and you should not allow rabies to occur. Go to the hospital for examination as soon as rabies occurs, control it with medication first, and then improve the virus. 1. What is rabies? Rabies, also known as hydrophobia, is an acute and fatal zoonotic infectious disease caused by the rabies virus that mainly invades the central nervous system. 2. How resistant is the rabies virus? Generally speaking, the rabies virus is not very resistant and can be destroyed by sunlight, ultraviolet rays and ultrasound. Strong alkali, strong acid, potassium permanganate and iodine can cause death, and it will die quickly in 1% formalin or 70% alcohol. Gradually loses its infectivity after drying. It is sensitive to temperature and can be completely killed by heating to 56°C for one hour, 60°C for 10-15 minutes, or 100°C for 2 minutes. But low temperature is a good living condition for viruses. The viruses in the brain blocks can be stored for several months at 4°C and for several years at -70°C, while still maintaining their infectious properties. Everyone must distinguish the difference between survival outside the body and survival in the air, because the rabies virus is an anaerobic bacterium, it loses its activity when it comes into contact with air, and it dies when the saliva dries up. The in vitro survival time refers to the situation where the environment is appropriate and there is a culture medium to provide nutrients to the virus. Do not confuse it with survival in the air. In the natural environment, the rabies virus quickly loses its activity and dies. Therefore, the US Centers for Disease Control and Prevention says that the rabies virus cannot be infected from a non-living organism. (That is, scratching, licking, and clawing, direct contact of active animals with wounds or mucous membranes. As for inactive objects (food, utensils, etc.) contaminated with the virus and then transmitted to living people, there is no such medical record. |
