What are harmful:
Bats are a natural reservoir of rabies and, according to the WHO, the Marburg, Ebola and coronaviruses, which are part of the group of especially dangerous infections - a list of the most dangerous known pathogenic viruses that cause fatal diseases to humans. There is evidence for the involvement of bats in the transmission of infection.
This biological hazard is a direct consequence of the lifestyle of these animals.
