It may also be possible for a person to contract SARS-CoV-2 by touching a surface that has contaminated droplets on it, then touching their mouth, nose, or eyes. when these droplets land in the mouth or nose of a person who is nearby.through respiratory droplets produced when a person with the infection coughs, sneezes, or talks.between people who are within 6 feet (2 meters) of each other.The Centers for Disease Control and Prevention (CDC) suggest that the virus spreads: Experts consider this to be between 2 and 14 days for SARS-CoV-2. The incubation period is the time that elapses between the virus entering the body and symptoms developing. However, there is growing evidence to suggest that the virus might also spread during the incubation period, before a person develops any symptoms. Most respiratory viruses are most contagious when a person has symptoms. According to the WHO, SARS-CoV-2 is not airborne, but other experts seem to disagree. The measles virus, for example, can remain contagious in the air for up to 2 hours.Īirborne viruses are the most contagious. Air currents can also carry them longer distances. However, other research has found they can travel 23–27 feet (7–8 meters).Īirborne particles are much smaller than droplets and can linger in the air for longer. Coughs and sneezes expel droplets from the body.Īccording to the WHO, these droplets are heavy enough that they cannot travel more than around 3 feet (1 meter). So far, they have been working from the knowledge they have of other coronaviruses, such as Middle East respiratory syndrome ( MERS) and severe acute respiratory syndrome (SARS).Įxperts tend to agree that coronaviruses are transmittable through the inhalation of droplets from a person who has the infection.
Virologists are still unsure about exactly how SARS-CoV-2 spreads. Share on Pinterest Researchers do not yet understand the extent to which the virus is airborne.
