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.
