Does a higher body temperature slow the corona virus down?
SARS-CoV-2 is believed to have spilled over into humans from a Rhinopholus (horseshoe bat) reservoir. During flight, bats' body temperature is maintained at levels associated with fever in other mammals. Rhinolophus bats are reported to reach skin temperatures of 41 C during flight. (From this review which describes why bats might be special sources for zoonotic viruses)
So, this virus is likely adapted to survive higher temperatures than a human host.
