Bats flying in the house may transmit the virus. In most cases, bats need to transmit the virus to humans through intermediate host animals, but the virus can also be transmitted through airborne and direct contact. There are many species of bats in China, mainly in Hainan, Guangdong, Guangxi, and Yunnan provinces, and the species of bats that carry the virus include the common bat, the Martesian daisy-headed bat, the big-hooved bat, and the brown fruit bat. Bats also carry many viruses, including encephalitis B virus, dengue fever virus, SARS coronavirus, rabies virus, etc. Bats can transmit viruses by airborne transmission, which come from glandular secretions or excretions of bats and are mainly present in the air in the form of aerosols, such as rabies virus and coronavirus may be transmitted in this way. In addition, viruses can be contracted after being scratched or bitten by a bat, eating a bat, or eating an animal that has preyed on a bat. Bat secretions or food eaten by bats may also contain viruses, and people may also become infected with the virus after coming in contact with these items. If you find a bat in your house, raise your awareness of self-protection and do not catch bats indiscriminately. If you are inadvertently bitten or scratched by a bat, go to the hospital for an examination and get a rabies vaccination.
