In Switzerland, 18 different species of bats carry 39 different families of viruses.
According to scientists from the University of Zurich, who published the results of the study, some viruses can be transmitted to humans.
Samples from the bats were taken between 2015 and 2020. It is specified that some of the viruses detected in them are zoonotic, that is, can be transmitted to humans. The study was conducted by analyzing DNA and RNA from various pathogens found in organ and fecal samples of the man-eating organisms.
Of the 39 viral families, 16 could be transmitted to other vertebrates. These include adenoviruses, which can cause pneumonia and viral meningitis, herpesviruses, rotaviruses and coronaviruses.
One of the bat colonies carried a nearly complete genome of a coronavirus associated with Middle East respiratory syndrome known as MERS-CoV. This virus can be transmitted to humans. It is thought to have a 35% mortality rate.
