Hemorrhagic fever can be prevented by paying attention to hygiene, vaccination and avoiding contact with infectious agents. 1. Pay attention to living hygiene: daily need to keep the environment hygiene clean, clean, regularly clean up the garbage. If you find rodent food and hiding places, you should use sticky boards, rodent traps and other tools to prevent and exterminate rodents in a timely manner. 2. Vaccination: There are vaccines for some hemorrhagic fever in the clinic, and you can prevent hemorrhagic fever by vaccination. 3. Avoid contact with infectious agents: Avoid contact with rodents on a daily basis. If your work requires you to work in the field, you can do a good job of protection, such as tightening your cuffs and pants and wearing gloves. If you are bitten by rodents accidentally, you should pay attention to disinfection in time and inject hemorrhagic fever vaccine and rabies vaccine. In daily life, you should wash your hands regularly, pay attention to hygiene and cleanliness, and avoid eating contaminated food.
