How Does Coronavirus Spread?
Experts believe the virus that causes COVID-19 spreads mainly from person to person. There are several ways
this
can happen:
- Droplets or aerosols. This is the most common transmission. When an infected person
coughs, sneezes, or talks, droplets or tiny particles called aerosols carry the virus into the air from their
nose or mouth.
Anyone who is within 6 feet of that person can breathe it into their lungs.
- Surface transmission. A less common method is when you touch surfaces that someone who
has
the virus has coughed or sneezed on. You may touch a countertop or doorknob that's contaminated and then touch
your nose, mouth, or eyes. The virus can live on surfaces like plastic and stainless steel for 2 to 3 days. To
stop it, clean and disinfect all counters, knobs,
and other surfaces you and your family touch several times a day.
- Airborne transmission. Research shows that the virus can live in the air for up to 3
hours.
It can get into your lungs if someone who has it breathes out and you breathe that air in.
Experts are divided on how often the virus spreads through the airborne route and how much it contributes to
the
pandemic.
