How does COVID-19 spread between people?
We know that the disease is caused by the SARS-CoV-2 virus, which spreads between people in several different ways.
How does Covid-19 spread between people?
The virus can be spread in the form of small liquid particles when coughing, sneezing, talking, singing, or breathing from the mouth or nose of an infected person. These particles range from larger respiratory droplets to smaller aerosols.
- Available evidence suggests that the virus spreads mainly between people who are in close contact with each other, typically within 1 meter (short range). A person can become infected when aerosols or droplets containing the virus are inhaled or come in direct contact with the eyes, nose, or mouth.
- The virus can also spread in crowded indoor spaces that are poorly ventilated and/or where people tend to spend longer periods of time. This is because aerosols are suspended in the air or travel more than 1 meter (long-range).
People can also become infected by touching surfaces contaminated with the virus by touching their eyes, nose, or mouth without cleaning their hands.
More research is ongoing to better understand the spread of the virus and which settings are the riskiest and why. Research is also ongoing to examine emerging virus variants and why some are more contagious.
