Press Release

Traveller with fever tests negative for MERS-CoV

30 May 2014

The Centre for Health Protection (CHP) of the Department of Health (DH) is today (May 30) investigating a suspected case of Middle East Respiratory Syndrome (MERS) whose respiratory specimen tested negative for MERS Coronavirus (MERS-CoV), and hence called on the public to stay alert and maintain good personal, food and environmental hygiene during travel.

The six-month-old baby boy with good past health developed fever and runny nose today. He travelled from the Kingdom of Saudi Arabia to Hong Kong for transit and was screened as febrile at the airport. The boy was sent to Princess Margaret Hospital for isolation and management and is in a stable condition.

Initial enquiries by the CHP revealed that the patient had had no contact with animals (including camels) and patients. His travel collaterals have remained asymptomatic so far.

His nasopharyngeal aspirate tested negative for MERS-CoV upon preliminary laboratory testing by the CHP's Public Health Laboratory Services Branch (PHLSB).

"We strongly advise travel agents organising tours to the Middle East not to arrange camel rides and activities involving camel contact, which may increase the risk of infection," a spokesman for the DH remarked.

"As pre-existing major illnesses can increase the likelihood of medical problems, including MERS, during travel, in view of recent pilgrimage activities, pilgrims should consult a healthcare provider before travelling to assess whether it is medically advisable," the spokesman advised.

Locally, the DH's surveillance mechanism with public and private hospitals, practising doctors and at the airport is well in place. Suspected cases identified will be sent to public hospitals for isolation and management until their specimens test negative for MERS-CoV.

"MERS is a statutorily notifiable infectious disease and the PHLSB is capable of detecting the virus. No human cases have been recorded so far in Hong Kong," the spokesman said.

"The Government will be as transparent as possible in the dissemination of information. Whenever there is a suspected case, particularly involving patients with travel history to the Middle East, the CHP will release information to the public as soon as possible," the spokesman added.

Early identification of MERS-CoV is important, but not all cases can be detected in a timely manner, especially mild or atypical cases. Healthcare workers (HCWs) should maintain vigilance and adhere to strict infection control measures while handling suspected or confirmed cases to reduce the risk of transmission to other patients, HCWs or visitors. Regular education should be provided.

Travellers returning from the Middle East who develop respiratory symptoms should wear face masks, seek medical attention and report their travel history to the doctor. HCWs should arrange MERS-CoV testing for them. Patients' lower respiratory tract specimens should be tested when possible and repeat testing should be undertaken when clinical and epidemiological clues strongly suggest MERS.

Travellers are reminded to take heed of personal, food and environmental hygiene:

• Avoid going to farms, barns or markets with camels;
• Avoid contact with animals (especially camels), birds, poultry or sick people during travel;
• Wash hands regularly before and after touching animals in case of visits to farms or barns;
• Do not drink raw milk, or consume foods which may be contaminated by animal secretions or products, unless they have been properly cooked, washed or peeled;
• Seek medical consultation immediately if feeling unwell;
• Avoid visits to healthcare settings with MERS patients;
• Wash hands before touching the eyes, nose and mouth, and after sneezing, coughing or cleaning the nose; and
• Wash hands before eating or handling food, and after using the toilet.
