How COVID-19 Spreads

COVID-19 is believed to be spread mainly through close person-to-person contact. Some people with no symptoms can spread the virus. We are still learning about how the virus spreads and about the severity of the disease it causes.

Person-to-person spread

The virus is thought to spread mainly from person to person.

• Between people who are in close contact (at a distance of up to about 6 feet).
• Through respiratory droplets that are produced when an infected person coughs, sneezes, or speaks.
• These droplets can end up in the mouth or nose of those who are nearby or possibly be inhaled and reach the lungs.
• People without symptoms can spread COVID-19.

 The virus spreads easily between people

The ease with which the virus spreads from person to person can vary. Some viruses are highly contagious, like the measles virus, while other viruses do not spread as easily. Another factor to consider is whether the spread is sustained, that is, it spreads continuously from person to person.

The virus that causes COVID-19 spreads very easily and continuously between people. Information about the ongoing pandemic of COVID-19 suggests that this virus spreads more efficiently than the influenza virus, but not as efficiently as the measles virus, which is a highly contagious virus. In general, the closer and longer the interaction between people, the greater the risk of COVID-19 spreading.

The virus can spread in other ways

It could be possible for a person to become infected with COVID-19 by touching a surface or object that has the virus, and then touching their mouth, nose, or eyes. This is not believed to be the primary way of spreading the virus, but we are still learning about how the virus spreads.

Propagation between animals and people

• At the moment, the risk of spreading COVID-19 from animals to people is considered low. Get to know El COVID-19 and pets and other animals.
• It appears that the virus that causes COVID-19 can spread from people to animals in certain situations. The CDC became aware of a small number of notifications from pets worldwide, including cats and dogs, infected with the virus that causes COVID-19, mainly after being in close contact with people with COVID-19. Know what to do if you have pets.

               Protect yourself and protect others

The best way to prevent the disease is to avoid exposure to this virus. You can take steps to slow down the spread.

• Observe social distancing measures (approximately 6 feet). It is very important to prevent the spread of COVID-19.
• Wash your hands often with soap and water. If you don't have soap and water, use a hand sanitizer that contains at least 60% alcohol.
• Routinely clean and disinfect frequently touched surfaces.
• Cover your mouth and nose with a cloth face covering when surrounded by other people.
