Press Release

Patient with fever tests negative for MERS-CoV

4 June 2014

The Centre for Health Protection (CHP) of the Department of Health (DH) is today (June 4) 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 51-year-old man, with an underlying medical condition, lives and works in Doha, Qatar. He presented with increased malaise upon arrival in Hong Kong from Doha on May 26. He attended the Accident and Emergency Department of Prince of Wales Hospital yesterday (June 3) and was admitted for management on the same day. He developed fever after admission and has been put under isolation. His current condition is stable.

Initial enquiries by the CHP revealed that the patient had no contact with animals (including camels) and MERS patients. His travel collateral has 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).

"Persons with pre-existing major illnesses, including chronic diseases such as diabetes, chronic lung disease and immunodeficiency, are more likely to develop severe infections for MERS if exposed to the virus," a spokesman for the DH said.

"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," the spokesman added.

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 CHP's 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. Health-care 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:

Tour leaders and tour guides operating overseas tours are advised to refer to the CHP's health advice against MERS (This link will open in a new windowwww.chp.gov.hk/en/view_content/26551.html).
