A room temperature above 30 C helps fight coronavirus?

Rumor: A room temperature above 30 C helps fight coronavirus.

Fact:

The novel coronavirus gradually loses its activity at whatever temperature, said Tang Qin, a researcher at the Chinese Medical Association. It loses its vitality slower at lower temperatures, and faster at higher temperatures, most rapidly at 56 C, she said. 

She said there is no clear evidence that the virus is deactivated much faster in a room temperature of 30 C than in winter outdoor temperatures.
