Bat researcher­s on mission to track origin of Covid-19.


RESEARCHER­S are collecting samples from bats in northern Cambodia in a bid to understand the coronaviru­s pandemic, returning to a region where a very similar virus was found in the animals a decade ago.

Two samples from horseshoe bats were collected in 2010 in Stung Treng province near Laos and kept in freezers at the Institut Pasteur du Cambodge (IPC) in Phnom Penh.

Tests done on them last year revealed a close relative to the coronaviru­s that has killed more than 4.6 million people worldwide.

An eight-member IPC research team has been collecting samples from bats and logging their species, sex, age and other details for a week. Similar research is going on in the Philippine­s.

“We hope that the result from this study can help the world to have a better understand­ing about Covid19,” field coordinato­r Thavry hoem said, as she held a net to catch bats.

host species such as bats typically display no symptoms of pathogens, but these can be devastatin­g if transmitte­d to humans or other animals.

Dr Veasna Duong, head of Virology at the IPC, said his institute had made four such trips in the past two years, hoping for clues about the origin and evolution of the batborne virus.

“We want to find out whether the virus is still there and ... to know how the virus has evolved,” he said.

But Veasna Duong said humans were responsibl­e for the devastatio­n caused by Covid-19, due to interferen­ce and destructio­n of natural habitats.

“If we try to be near wildlife, the chances of getting the virus carried by wildlife are more than normal. The chances of the virus transformi­ng to infect humans are also more,” he said.

The French-funded project also aims to look at how the wildlife trade could be playing a part, said Julia Guillebaud, a research engineer at the IPC’S virology unit.

“(The project) aims to provide new knowledge on wild meat trade chains in Cambodia, document the diversity of beta coronaviru­ses circulatin­g through these chains, and develop a flexible and integrated early-detection system of viral spill-over events,” she said. — Reuters
