Coronavirus

Coronaviruses are a group of viruses that can cause either mild illness, such as a cold, or can make people sick with pneumonia.

If you are a medical provider, see our 2019 Novel Coronavirus (COVID-19) — Information for Providers page.

2019 Novel Coronavirus

Recently, a novel (new) coronavirus was detected in thousands of people worldwide, primarily in China. There is evidence the infection can be spread person-to-person. A "novel coronavirus" is a strain that has not been previously found in humans.

No people have been diagnosed with this novel coronavirus in New York City (see up-to-date case count). The risk to New Yorkers of contracting this novel coronavirus is low. If you are experiencing symptoms and want to get tested, talk to your health care provider.

There are no specific vaccines or treatments available for this novel coronavirus, or any other coronavirus.

If you are planning any travel outside the US, visit CDC’s Travelers’ Health webpage for the latest travel health notices.

Symptoms

Symptoms for this novel coronavirus, also referred to as COVID-19, can include fever, cough or shortness of breath. An infection can result in death, but that is a rare outcome.

Prevention

You should go about your daily life, but take the same precautions that you would during cold and flu season:

  • Get your flu shot — it’s not too late.
  • Cover your nose and mouth with a tissue or sleeve when sneezing or coughing — do not use your hands.
  • Wash your hands often with soap and water.
  • Stay home if you are not feeling well.

Other Coronaviruses

General Symptoms and Prevention

Human coronaviruses usually cause mild-to-moderate illness in people. Symptoms can include:

  • Runny nose
  • Headache
  • Cough
  • Sore throat
  • Fever

To reduce your risk of infection:

  • Wash your hands often with soap and warm water for at least 20 seconds.
  • Avoid touching your eyes, nose or mouth with unwashed hands.
  • Avoid close contact with people who are sick.

MERS and SARS

Two human coronaviruses — MERS-CoV and SARS-CoV — can frequently cause severe illness. MERS symptoms usually include fever, cough, and shortness of breath which often progress to pneumonia. About three out of every 10 patients reported with MERS have died. MERS cases continue to occur, primarily in the Arabian Peninsula.

SARS symptoms often include fever, chills and body aches. These symptoms usually progress to pneumonia. No human cases of SARS have been reported anywhere in the world since 2004.

MERS and SARS are different coronaviruses from the 2019 outbreak that started in China.
