Close kin to new coronavirus found in Euro bats


TORONTO - Viruses closely related to the new coronavirus that emerged last year in the Middle East have been discovered in specimens from a number of species of bats found widely throughout Europe and beyond, a new study shows.

The work suggests bats common to Europe, Russia, parts of Asia and Africa and the Middle East may carry viruses that are very closely related to the new coronavirus, called EMC 2012.

The study will be published in the March issue of the journal Emerging Infectious Diseases.

The findings, while interesting, don't help to narrow down how a dozen or more people in three countries have been sickened by the new virus, or whether more have been infected but have escaped notice because their symptoms were mild.

The researchers said bats from the Arabian Peninsula should be tested to see if they carry similar viruses. But senior author Dr. Christian Drosten cautioned that because of the wide geographic distribution of these bats, it cannot be concluded that the bat virus that evolved into the new coronavirus did so in the Middle East.

"It could have come up in any other region where those bats are prevalent," said Drosten, a coronavirus expert and director of the Institute of Virology at the University of Bonn Medical Centre in Germany.

While it is believed the new virus came from bats, it's not known whether it moved directly from bats to people -- through exposure to bat guano or urine, for instance -- or whether some other animal or animals such as some form of livestock became infected and passed the virus on.

The SARS coronavirus, a cousin of EMC 2012, evolved from a bat virus that made its way into wild animals -- civet cats and raccoon dogs -- that are eaten as delicacies in China. "We don't know (yet) what the raccoon dog is for this virus, but there may be one," Drosten said.

He and colleagues had done previous research on bats in Ghana and in four countries in Europe -- the Netherlands, Romania, Germany and Ukraine. As a result of that earlier work, they had stored fecal samples from nearly 5,000 bats. After EMC 2012 emerged, they tested the samples looking for coronaviruses. …
