Is MERS the same as SARS?

No. Although in the same general family of viruses, the virus that causes MERS (MERS coronavirus or MERS-CoV) is different from the virus that caused Severe Acute Respiratory Syndrome (SARS). There have been no cases of SARS since 2004.

What are the symptoms of MERS?

Symptoms typically include fever, cough and shortness of breath. People with weakened immune systems may experience more severe symptoms.

Where did the virus come from?

It is currently not known where MERS-CoV came from, but research suggests that people originally became infected through contact with animals such as camels or bats.

Is MERS contagious?

People may occasionally transmit the virus to others through very close contact. However, this is rare, and the risk to the general population of New York City is very low at this time.

Is there a vaccine or treatment for MERS?

There is no vaccine or treatment for MERS, but medical care is supportive and can help relieve symptoms.

Has anyone in the United States gotten infected?

Yes, there have been a few cases of MERS diagnosed in the United States.  So far, these have been isolated cases and there has been no spread to other people.  The risk of MERS to the general public in this country remains very low.

What is the Health Department doing about MERS?

The Health Department is working with the CDC to prevent the spread of MERS through surveillance and testing, and by providing information to health care providers and the general public. The Health Department is also working with JFK Airport to coordinate response measures if a suspected MERS case is identified on an airplane.

Should I call my doctor if I recently traveled to countries in or around the Arabian Peninsula and I become ill?
