Risk Factors

Things that raise the risk of MERS are:
  • Recent travel to countries in or near the Arabian Peninsula
  • Close contact with someone who:
    • Has MERS
    • Has been exposed to MERS
  • Caring for patients with MERS—or handling their lab specimens
  • Exposure to camels that have MERS

Symptoms

Some people with MERS have no symptoms. Others may have mild to severe symptoms. They may be:
  • Fever
  • Cough
  • Problems breathing
  • Sore throat
  • Muscle pain
  • Nausea and vomiting
  • Diarrhea

Diagnosis

The doctor will ask about your symptoms and health history. A physical exam will be done.
Tests may be done to diagnose the infection. They may include:
  • A sputum test
  • Nasal and throat swabs
  • Blood tests
Chest x-rays, may be done to look for lung problems.

Treatment

Currently, there is no specific treatment for MERS. The goal is to ease symptoms and prevent problems. This may include breathing support in the hospital.

Prevention

The risk of MERS or any virus may be reduced by:
  • Washing hands frequently
  • Not touching the eyes, nose, and mouth
  • Avoiding close contact with sick people and their items, such as utensils
