Human activities create pathways for viruses
|
COVID-19 — the virus behind the current pandemic — is only the latest virus to cross over from bats to human populations. Farming, animal trade, global travel, hunting and habitat destruction, among others, put us in close contact with the sources of several viruses. Ebola, SARS and MERS were among the viruses that affected human populations globally. But what is it about bats that make them a regular source of deadly disease? Today in The Conversation Canada, cellular microbiologist Narveen Jandu of the University of Waterloo takes a look at how
these viruses make their way into human populations.
