This is how quickly coronavirus spreads, how it affects you
The virus is thought to spread mainly from person-to-person, typically between people who are in close contact with one another (within about 6 feet).
Through respiratory droplets produced when an infected person coughs or sneezes. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.
The most spread is from droplets produced when an infected person coughs, which are inhaled by people nearby. Transmission from touching contaminated surfaces hasn’t been shown yet, though recent tests by U.S. scientists suggest it’s possible — one reason they recommend washing your hands and not touching your face.
The virus can live in the air for several hours, up to 24 hours on cardboard and up to two to three days on plastic and stainless steel. Cleaning surfaces with solutions containing diluted bleach should kill it.
Can someone spread the virus without being sick?
People are thought to be most contagious when they are most symptomatic (the sickest)
Some spread might be possible before people show symptoms; (Up to 28 Days) there have been reports of this occurring with this new coronavirus, but this is not thought to be the main way the virus spreads.
Spread from contact with contaminated surfaces or objects
How easily a virus spreads from person-to-person can vary. Some viruses are highly contagious (spread easily), like measles, while other viruses do not spread as easily. Another factor is whether the spread is sustained, spreading continually without stopping.
Covid19 can remain on various surfaces for a prolonged amount of time. See Covid19 Surface Survival Time for detailed information.
Prevent the Spread by Washing your Hands Often
- Wash your hands often with soap and water for at least 20 seconds especially after you have been in a public place, or after blowing your nose, coughing, or sneezing.
- If soap and water are not readily available, use a hand sanitizer that contains at least 60% alcohol. Cover all surfaces of your hands and rub them together until they feel dry.
- Avoid touching your eyes, nose, and mouth with unwashed hands.
