Rats are the storage host or transmission medium of many diseases, such as plague, epidemic hemorrhagic fever, ectoparasites of rats, etc., which are transmitted to humans through biting and sucking blood.
Mice with pathogenic microorganisms in their bodies pollute food or water sources through mouse activities or feces, which causes diseases after human consumption. Rats bite directly or pathogens invade through trauma, causing infection.

The harm of rats to people
1. Mice are disseminators of many diseases, which can be directly or indirectly transmitted to humans through humans or some parasites. They can spread more than 35 diseases, such as plague or epidemic hemorrhagic fever.
2. Rats will carry more bacteria. If humans don't clean up in time after eating some food, it will be very easy to bring these bacteria into the body if humans eat these foods after being touched by mice.
3. Rats often carry a large number of fleas. If these fleas run into the human body, humans may have itchy skin or cause some infections.
