Bats can be infected with viruses when they fly into your home. Transmission of disease from bats to humans generally requires an intermediate host, but in rare cases, transmission can occur through direct contact with humans or through the air. Viruses carried by bats include SARS coronavirus, encephalitis B virus, and rabies virus. The rabies virus carried by bats can be transmitted to humans in the form of aerosols in the air through bat feces, and indirectly through contact with human food and utensils. In conclusion, when bats fly into your home, you should be aware of the need to take precautions, especially if you are scratched or bitten by bats, you should seek medical treatment in time.
