How does the virus spread?

COVID-19 is thought to spread mainly through close contact from person-to-person. Some people without symptoms may be able to spread the virus. We are still learning about how the virus spreads and the severity of illness it causes. The virus that causes COVID-19 is spreading very easily and sustainably between people. Information from the ongoing COVID-19 pandemic suggests that this virus is spreading more efficiently than influenza, but not as efficiently as measles, which is highly contagious. It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes.

Person-to-person spread

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

  • Between people who are in close contact with one another (within about 6 feet).
  • Through respiratory droplets produced when an infected person coughs, sneezes, or talks.
  • These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.
  • COVID-19 may be spread by people who are not showing symptoms.

Those at high-risk for severe illness from COVID-19 are:

  • People 65 years and older

People of all ages with underlying medical conditions:

What steps should you take to protect yourself and others?

  • 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.
  • Avoid touching your eyes, nose, and mouth with unwashed hands.
  • Avoid close contact with people who are sick.
  • Put distance between yourself and other people if COVID-19 is spreading in your community.
  • Stay home if you are sick, except to get medical care.
  • Cover your mouth and nose with a tissue when you cough or sneeze or use the inside of your elbow.
  • Clean and disinfect frequently touched surfaces daily. This includes tables, doorknobs, light switches, countertops, handles, desks, phones, keyboards, toilets, faucets, and sinks.

How to Wear a Cloth Face Covering?

CDC recommends wearing cloth face coverings in public settings where other social distancing measures are difficult to maintain (e.g., grocery stores and pharmacies), especially in areas of significant community-based transmission. Cloth face coverings should not be placed on young children under age 2, anyone who has trouble breathing, or is unconscious, incapacitated or otherwise unable to remove the mask without assistance.

Cloth face coverings should:

  • fit snugly but comfortably against the side of the face
  • be secured with ties or ear loops
  • include multiple layers of fabric
  • allow for breathing without restriction
  • be able to be laundered and machine dried without damage or change to shape

What to do if you believe you may be infected?

If you think you have been exposed to COVID-19 and develop a fever and symptoms, such as cough or difficulty breathing:

  • Stay home: People who are mildly ill with COVID-19 are able to recover at home. Do not leave, except to get medical care.
  • Avoid public areas and public transportation.
  • Separate yourself from other people in your home and limit contact with pets and animals.
  • If you have a medical appointment, call your doctor’s office, and tell them you have or may have COVID-19. This will help the office protect themselves and other patients.

When should I seek medical attention?

If you develop emergency warning signs for COVID-19 get medical attention immediately. Emergency warning signs include:

  • Trouble breathing
  • Persistent pain or pressure in the chest
  • New confusion or inability to arouse
  • Bluish lips or face

When to quarantine?

Stay home if you might have been exposed to COVID-19. You should stay home for 14 days after your last contact with a person who has COVID-19.

Stay home and monitor your health

  • Stay home for 14 days after your last contact with a person who has COVID-19
  • Watch for fever (100.4◦F), cough, shortness of breath, or other symptoms of COVID-19
  • If possible, stay away from others, especially people who are at higher risk of getting very sick from COVID-19
