Most people who got infected with MERS-CoV developed severe acute respiratory illness with symptoms of fever, cough, and shortness of breath. 30% of them died. Some people were reported as having a mild respiratory illness.
Q: What is the source of MERS-CoV?
A: We don’t know for certain where the virus came from. However, it likely came from an animal source. In addition to humans, MERS-CoV has been found in camels in Qatar, Egypt and Saudi Arabia, and a bat in Saudi Arabia. Camels in a few other countries have also tested positive for antibodies to MERS-CoV, indicating they were previously infected with MERS-CoV or a closely related virus. However, we don’t know whether camels are the source of the virus. More information is needed to identify the possible role that camels, bats, and other animals may play in the transmission of MERS-CoV.
Q: Is CDC concerned?
A: Yes, CDC is concerned about MERS-CoV. Most people who have been confirmed to have MERS-CoV infection developed severe acute respiratory illness. They had fever, cough, and shortness of breath. About 30% of these people died. Also, in other countries, the virus has spread from person to person through close contact, such as caring for or living with an infected person. CDC recognizes the potential for the virus to spread further and cause more cases globally, including in the United States.
Q: Has anyone in the United States gotten infected?
A: Yes, on May 2, 2014, the first U.S. case of MERS was confirmed in a traveler from Saudi Arabia to the U.S. The traveler is considered to be fully recovered and has been released from the hospital. Public health officials have contacted healthcare workers, family members, and travelers who had close contact with the patient. At this time, none of these contacts has had evidence of being infected with MERS-CoV.
