Phillip Alviola, a bat ecologist, attempts to catch a bat that was caught on a mist net that was set up in front of a building with a bat roost at the University of the Philippines Los Banos (UPLB), in Los Banos, Laguna province, Philippines, February 19, 2021. "What we're trying to look into are other strains of coronavirus that have the potential to jump to humans," said Alviola. "If we know the virus itself and we know where it came from, we know how to isolate that virus geographically." REUTERS/Eloisa Lopez SEARCH "LOPEZ BATS" FOR THIS STORY.
