<div> <p>By Cindy Liu and Prak Chan Thul</p> <p><span class="caps">STUNG</span> <span class="caps">TRENG</span>, Cambodia – 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.</p> <p>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 (<span class="caps">IPC</span>) in Phnom Penh.</p> <p>Tests done on them last year revealed a close relative to the coronavirus that has killed more than 4.6 million people worldwide. </p> <p>An eight-member <span class="caps">IPC</span> research team has been collecting samples from bats and logging their species, sex, age and other details for a week. Similar research https://reut.rs/3EsZXVO is going on in the Philippines.</p> <p>“We hope that the result from this study can help the world to have a better understanding about <span class="caps">COVID</span>-19,” field coordinator Thavry Hoem told Reuters, as she held a net to catch bats.</p> <p>Host species such as bats typically display no symptoms of pathogens, but these can be devastating if transmitted https://tmsnrt.rs/3lvfsE9 to humans or other animals.</p> <p>Dr. Veasna Duong, Head of Virology at the <span class="caps">IPC</span>, said his institute had made four such trips in the past two years, hoping for clues about the origin and evolution of the bat-borne virus.</p> <p>“We want to find out whether the virus is still there and … to know how the virus has evolved,” he told Reuters.</p> <p>Deadly viruses originating from bats include Ebola and other coronaviruses such as Severe Acute Respiratory Syndrome (<span class="caps">SARS</span>) and Middle East Respiratory Syndrome (<span class="caps">MERS</span>).</p> <p>But Veasna Duong said humans were responsible for the devastation caused by <span class="caps">COVID</span>-19, due to interference and destruction of natural habitats. </p> <p>“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. </p> <p>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 <span class="caps">IPC</span>’s virology unit.</p> <p>“(The project) aims to provide new knowledge on wild meat trade chains in Cambodia, document the diversity of betacoronaviruses circulating through these chains, and develop a flexible and integrated early-detection system of viral spill-over events,” Gillebaud said. </p> <p/> </div>
