[Test] Coronaviruses

Coronaviruses are a large group of viruses that can cause mild to serious respiratory illness. 

Most people get a coronavirus infection at some point in their lives — often as a common cold. Young children are at higher risk for infection.

Some types, like COVID-19, SARS and MERS, can cause more serious disease.

Types of Coronaviruses

About COVID-19, how it spreads, symptoms, vaccines, testing and what to do if you're sick

Middle East Respiratory Syndrome (MERS)

MERS was first reported in 2012. Find out how it spreads and what to do if you think you've been exposed.

Severe Acute Respiratory Syndrome (SARS)

SARS spread worldwide in 2003 before it was contained. This page contains historical information and what scientists learned from that outbreak.

How Coronaviruses Spread

Coronaviruses usually spread through:

  • Coughing and sneezing
  • Close personal contact, like hugging or shaking hands
  • Touching surfaces with the virus and then touching your eyes, nose or mouth

There are currently no vaccines for most coronaviruses except COVID-19. 

About COVID-19 Vaccines

You can lower your risk:

  • Wash your hands often with soap and water
  • Avoid touching your eyes, nose and mouth

Testing and Treatment

Lab tests can confirm a coronavirus infection, but testing is usually not needed for mild illness.

Most people get better on their own. You can:

  • Take medicine for fever or pain (do not give aspirin to children)
  • Use a humidifier or take a warm shower to ease cough and sore throat

If your symptoms get worse or you're worried, see your health care provider.
