[ti:Does Weather Affect the Coronavirus Outside?]
[00:00.04]Does weather affect the spread of the coronavirus
[00:03.44]outside a building, in the open air?
[00:07.08]Not really, experts say.
[00:10.84]The World Health Organization (WHO) says
[00:13.28]the virus can be spread in any kind of weather.
[00:17.68]There is also no reason to believe that cold weather can kill it.
[00:25.12]The WHO says the virus is mainly spread between people.
[00:31.72]Rain and snow may help reduce the amount of the virus
[00:36.20]on chairs or other outside objects.
[00:40.48]But spread of the virus from surfaces is not believed
[00:45.08]to be a major contributor to the COVID-19 health crisis.
[00:49.96]Scientists say the real concern about cold weather
[00:56.20]is that lower temperatures are more likely to keep people indoors.
[01:02.48]They also are more likely to be in more crowded spaces,
[01:07.96]where the virus can spread more easily.
[01:11.68]Studies have shown that a large percentage of spread
[01:16.88]happens within homes when people
[01:19.68]are sharing common areas like bathrooms.
[01:24.00]The WHO and others have also warned about the virus spreading
[01:31.20]in indoor areas with poor ventilation.
[01:35.80]They note the virus can be spread in the air, and infectious particles
[01:41.40]might remain in the air for several hours.
[01:45.32]Some infections have been linked to nightclub visits,
[01:50.28]working out at physical exercise centers,
[01:53.96]and even performing with other people as part of a singing group.
[02:00.36]The coronavirus does not spread as often outdoors
[02:04.44]because fresh air breaks up the virus particles.
[02:09.76]People also have an easier time keeping their distance
[02:14.00]from others in outdoor areas.
[02:18.12]But experts warn that coronavirus spread is still possible
[02:22.84]if people spend extended periods of time outdoors
[02:27.28]close to others without covering their nose and mouth.
[02:32.68]Health officials say the best way to stop spread of the virus
[02:38.28]is to wear a face mask in public,
[02:41.52]stay at least 2 meters away from people not in your home
[02:46.44]and repeatedly wash your hands.
