17 WHO Travel Advice 1 At this time, the risk to an individual pilgrim of contracting MERS-CoV is considered very low. WHO does not recommend the application of any travel or trade restrictions or entry screening. Before departure, pilgrims should be advised: – Pre-existing major medical conditions can increase the likelihood of illness, including MERS-CoV infection, during travel – Pilgrims should consult a health care provider to review the risk and assess whether making the pilgrimage is advisable

18 WHO Travel Advice 2 Dissemination of general travel health precautions, which will lower the risk of infection in general. Specific emphasis should be placed on: – Washing hands often with soap and water, or with hand rub – Adhering to good food-safety practices (avoiding undercooked meat or food prepared under unsanitary conditions, and properly washing fruits and vegetables before eating them) – Maintaining good personal hygiene – Avoiding unnecessary contact with farm, domestic, and wild animals

19 WHO Travel Advice 3 Travelers who develop a significant ARI with fever and cough (severe enough to interfere with usual daily activities) should be advised to: – Minimize their contact with others – Adopt cough etiquette: Cover their mouth and nose with a tissue when coughing or sneezing and discard the tissue in the trash after use and wash hands afterwards, or, if this is not possible, to cough or sneeze into upper sleeves of their clothing, but not their hands – Report to the medical staff

20 WHO Travel Advice 4 Patients: – Returning pilgrims developing a significant ARI with fever and cough during the two weeks after their return should seek medical attention. – Persons who have had close contact with a pilgrim or traveler with a significant ARI with fever and cough and who themselves develop such an illness should seek medical attention. Clinicians: – Practitioners and facilities should be alerted to the possibility of MERS-CoV infection in returning pilgrims with ARI, especially those with fever and cough and pulmonary parenchymal disease – If clinical presentation suggests the diagnosis of MERS-CoV, laboratory testing, should be done and infection prevention and control measures implemented.
