Travel advice

MERS has been identified and linked to human infections in dromedary camels in several countries in the Middle East, Africa and South Asia.

Anyone travelling to these areas should review the travel advice and remain alert for symptoms.

Risk from camels

Camels in the Middle East are suspected to be the primary source of infection for humans.

Travellers in the Middle East should:

  • avoid all contact with camels 
  • not drink raw camel milk or camel urine
  • not eat camel meat unless it has been properly cooked.

Hospital outbreaks

MERS-CoV does not seem to pass easily from person to person but transmission is more likely in certain settings, such as occurs when providing unprotected care to a patient.

Hospitals outbreaks of MERS-CoV are well known, making the strict and timely application of appropriate infection prevention and control measures vital.
