How common is fever in MERS coronavirus infection?

MERS coronavirus infection can cause fever as part of an illness affecting the respiratory system. Someone may also have cough, shortness of breath, fatigue, muscle aches, or gastrointestinal symptoms. Severity varies, and some people can become seriously unwell, especially if breathing becomes difficult.

A fever on its own does not tell you which infection is responsible. A clinician will consider the full symptom pattern, recent travel, possible exposure, and close contact with unwell people when deciding on next steps.

If MERS coronavirus infection is a concern, contact a healthcare service for advice before visiting in person. Follow instructions about where to go and how to limit close contact with others. Rest, take fluids, and note any change in cough, breathing, chest discomfort, alertness, or ability to keep fluids down.

Seek urgent medical care for trouble breathing, blue or grey lips, chest pain, confusion, inability to stay awake, signs of dehydration, or a sudden worsening of illness. People with long-term medical conditions or weakened immunity should seek prompt advice for fever with respiratory symptoms or a relevant exposure.

Ask whether your symptoms and exposure history require testing, which precautions are appropriate at home, and when you can safely be around others. Ask which breathing or hydration changes mean you should seek emergency help.
