Close relatives of the coronavirus may have been in bats for decades

    Viruses from the coronavirus lineage responsible for Covid-19 have been circulating in bats for decades, long before the virus started infecting people last year, a new study suggests.

    How exactly the virus jumped to humans is still a mystery. But the study suggests the coronavirus most likely evolved in bats — such as intermediate horseshoe bats, the source of the coronavirus that caused the 2003–2004 SARS outbreak — not snakes or pangolins as some researchers have suggested. Pangolins or another animal might still have been an intermediate host before the virus made it to humans.

    Based on the evolutionary relationship among the 68 coronaviruses, the researchers estimate that the coronavirus lineage that gave rise to the virus behind the pandemic has been present in bats for decades.

    That long period hints that more bat viruses with the potential to infect humans are circulating in horseshoe bats. Searching for such bat viruses can help identify potential threats before the pathogens make the jump, the team writes.
