All over Asia and Africa human beings encounter horseshoe bats, any one of which could be carrying a virus that could start an epidemic if amplified in a market or similar setting. Bats have supplied most of the dangerous new diseases of the past two decades. The natural reservoir of rabies is in bats, especially in the Americas. Ebola, Marburg and other highly dangerous viruses come from bats, mainly in Africa. The Hendra and Nipah viruses are caught from fruit bats and have caused lethal but small outbreaks in south Asia and Australia. And most coronaviruses seem to originate in bats, including SARS and MERS, a frequently fatal illness that people in the Middle East began catching from camels in 2012, the camels having picked it up from bats.
In a paper published in February last year, Patrick Woo and colleagues at Hong Kong University surveyed the coronaviruses found in bats and came to a prescient conclusion: “Bat–animal and bat–human interactions, such as the presence of live bats in wildlife wet markets and restaurants in Southern China, are important for interspecies transmission of [coronaviruses] and may lead to devastating global outbreaks.”
We had fair warning with Ebola, Hendra, Nipah, MERS and SARS, and the Yunnan cave discovery in 2013 should have sounded a loud alarm. Even when this pandemic is over, others are possible.
