Hazard Recognition

The risk of infection with MERS-CoV in the U.S. is low. So far, transmission is limited to persons who have had direct contact with dromedary camels and those who have been in close contact with a person who is symptomatic with MERS.

Healthcare providers should be aware of the need to assess MERS-CoV exposure history, risk factors, and signs/symptoms of infection, especially in ill persons who have recently traveled from countries in or near the Arabian Peninsula or other areas with a reported case cluster(s). A person who develops severe acute lower respiratory illness (e.g., requiring hospitalization) and who has been in a healthcare facility in a region with a reported case cluster(s) within 14 days prior to illness onset should be evaluated for MERS. Use appropriate infection control measures when working with anyone presenting clinical symptoms and risk factors for MERS. All patient evaluations should occur in consultation with state and local health departments.

The CDC Prevention and Control for Hospitalized Patients page provides additional information for clinicians.

Because most instances of person-to-person spread have occurred in healthcare workers and other close contacts, the WHO is currently not advising special screenings at points of entry or recommending the application of travel or trade restrictions related to MERS-CoV. In the event of future MERS outbreaks, employers and workers should consult the CDC web site for travel recommendations and the U.S. Department of State web site for travel alerts or warnings.
