A study related to Coronaviruses (Remember SARS? Man, those were the days) and temperature. At 4*C the test viruses lived for 28 days. The warmer it got, the faster they croaked. High temps and high humidity were the most destructive, the viruses only remained viable for a few hours at 40*C and 80% humidity.
