What is the current situation?

On May 20, the Republic of Korea reported its first laboratory confirmed case of Middle Eastern respiratory syndrome (MERS). As of June 5, 36 cases in the Republic of Korea have been confirmed by the World Health Organization, all linked to healthcare facilities with a confirmed MERS case.

What is MERS?

MERS, a viral respiratory illness, was first reported in Saudi Arabia in 2012. Symptoms of MERS include fever, cough, and shortness of breath.

What can travelers do to prevent MERS?

All travelers can take these everyday actions to help prevent the spread of germs and protect against colds, flu, and other illnesses, including MERS:

• Wash your hands often with soap and water. If soap and water are not available, use an alcohol-based hand sanitizer.
• Avoid touching your eyes, nose, and mouth; germs spread this way.
• Avoid close contact with sick people.
• Be sure you are up-to-date with all of your shots and, if possible, see your healthcare provider at least 4-6 weeks prior to travel to get any additional shots.
• Visit CDC’s Travelers’ Health website for more information on healthy travel.
• If you are sick:
  • Cover your mouth with a tissue when you cough or sneeze, and throw the tissue in the trash.
  • Avoid contact with other people to keep from infecting them.
  • Contact your doctor if you develop a fever and symptoms of lower respiratory illness, such as cough or shortness of breath, within 14 days after being in a healthcare facility in the Republic of Korea. Tell your doctor  about your recent travel and presence in a healthcare facility before you go in for an appointment.

Clinician Information

Healthcare providers should be alert to patients who develop severe acute lower respiratory illness (e.g., requiring hospitalization) and were present in a healthcare facility in the Republic of Korea within 14 days before illness onset.

• Consider other more common causes of respiratory illness, such as influenza.
• Evaluate patients using CDC’s MERS case definitions and guidance, where additional information is available.
• Immediately report patients with unexplained respiratory illness who meet CDC’s criteria for patient under investigation (PUI) for MERS to CDC through the state or local health department.
• Contact your state or local health department if you have any questions.
• See additional recommendations and guidance on CDC’s MERS website.
• Health departments with questions should contact CDC’s Emergency Operations Center (770-488-7100).
