SARS CoV 2 coronaviruses related to Cambodian bats in 2010 – Study

New York, Nov 24, : A team of scientists from around the world has identified coronaviruses that are closely related to SARS CoV-2 in two bats from Cambodia that were tested more than a decade ago.
The discovery in Nature Communications and the recent detection in Laos of the closest ancestors to SARS-CoV-2 in cave-dwelling bats in Laos suggests that SARS-CoV-2-related virus that causes Covid-19 have a wider geographic distribution than previously reported.This supports the hypothesis of a spillover from a bat-borne disease.

A team of scientists from the US and France used metagenomic sequencing for the identification of nearly identical viruses in two Shamel’s horseshoe bats (Rhinolophus Shameli) that were originally collected in 2010.

This suggests that SARS-CoV-2-related viruses may circulate via multiple Rhinolophus species.

Researchers stated that current knowledge of the geographic distributions of the SARS-CoV lineages and SARS-CoV-2 linesages may reflect a lack in sampling in Southeast Asia or at least within the Greater Mekong Subregion.

This region includes Myanmar, Laos and Thailand, Cambodia, Vietnam, and the Yunnan, Guanxi, provinces of China.

The authors also note that pangolins and certain species of cat, weasel, and civet found in this area are susceptible to SARS-CoV-2 infection.They could be intermediary hosts for humans.

In 2020, viruses belonging to the SARS-CoV-2 sublineage were found in distinct pangolin groups seized in anti-smuggling operations in southeast China.

Although it is impossible to determine the exact location of these pangolins, it is important that you note that the natural geographical range of the pangolin species (Manis Javanica) corresponds to Southeast Asia, not China.

These findings highlight the importance of regional-wide investments in bridging capacities for sustainable surveillance of wildlife pathogens.

Southeast Asia is home to a wide range of wildlife, and humans are often in direct contact with wild hosts of SARS-like coronaviruses.Lucy Keatts, co-author of this study and member of the Wildlife Conservation Society’s Health Programme (WCS), said Lucy Keatts.

Keatts explained that this was due to “regional land-use changes such infrastructure development, urbanization, and agricultural expansion that can increase contact between bats, domestic animals, and humans.” Future pandemic preparedness and prevention will require continued and expanded surveillance of bats in Southeast Asia and other key wild animals.
