As to the question whether the virus thrives in the heat or cold, studies
reveal it is ‘highly sensitive’ to hot temperature. However do not bank on the hot seasons to wipe it all off with a single strike.

Pathogen appears to spread fastest at 8.72 degrees Celsius, so countries in colder climes should ‘adopt the strictest control measures’, according to researchers from Sun Yat-sen University in Guangdong province.

The study, by a team from Sun Yat-sen University in Guangzhou, the capital
of south China’s Guangdong province, sought to determine how the spread of the new coronavirus might be affected by changes in season and temperature.

Published last month, though yet to be peer-reviewed, the report suggested heat had a significant role to play in how the virus behaves. “Temperature could significantly change Covid-19 transmission,” it said. “And there might be a best temperature for viral transmission.”

The “virus is highly sensitive to high temperature”, which could prevent it
from spreading in warmer countries, while the opposite appeared to be true in colder climates, the study said. As a result, it suggested that “countries and regions with a lower temperature adopt the strictest control measures”.


  • Avoid contact with sick people.
  • Avoid touching your eyes, nose, or mouth with unwashed hands.
  • Clean your hands often by washing them with soap and water for at least 20 seconds or using an alcohol-based hand sanitizer that contains at least 60%–95% alcohol. Soap and water should be used if hands are visibly dirty.
  • It is especially important to clean hands after going to the bathroom; before eating; and after coughing, sneezing or blowing your nose.
  • Supplies of hand sanitizer, tissues, and other hygiene products may be limited, so consider bringing them with you.
  • Avoid traveling if you are sick.
