NEW DELHI: A report from an international team tasked with finding the origin of SARS-COV2 said that the origin of the novel coronavirus was unclear, but the most probable reservoir source of the virus was bats and that it indirectly spilled over to cause disease in humans somewhere in November 2019.While the report was inconclusive and that bats were most likely to have been the reservoir host for the virus, it said that since there is usually limited close contact between humans and bats, it is likely that transmission of the virus to humans happened through an intermediate host.A reservoir is the primary host that harbours the virus but shows no ill effects, while the intermediate host is another animal species more likely to be handled.
