Middle East respiratory syndrome coronavirus (MERS-CoV) - update
29 August 2013 - WHO has been informed of an additional two laboratory-confirmed cases of Middle East respiratory syndrome coronavirus (MERS-CoV) infection in Qatar.
The patients include a 59-year old man with an underlying medical condition who became ill on 15 August 2013. He is currently hospitalised and is in stable condition.
Preliminary epidemiological investigations reveal that the patient travelled to Medina, Saudi Arabia for 6 days and returned to Qatar on 15 August 2013. He did not take part in Umrah and did not visit to Al-Masjid an-Nabawi in Medina. Further investigation is on-going.
The second patient is a 29-year-old man with an underlying medical condition who had no history of recent travel outside the country.
The results of both the cases were confirmed by an international reference laboratory. A total of 138 healthcare workers, family and community contacts have been screened in the country and so far all tested negative for MERS-CoV infection.
Globally, from September 2012 to date, WHO has been informed of a total of 104 laboratory-confirmed cases of infection with MERS-CoV, including 49 deaths.
Based on the current situation and available information, WHO encourages all Member States to continue their surveillance for severe acute respiratory infections (SARI) and to carefully review any unusual patterns.
Health care providers are advised to maintain vigilance. Recent travellers returning from the Middle East who develop SARI should be tested for MERS-CoV as advised in the current surveillance recommendations.
Specimens from patients’ lower respiratory tracts should be obtained for diagnosis where possible. Clinicians are reminded that MERS-CoV infection should be considered even with atypical signs and symptoms, such as diarrhoea, in patients who are immunocompromised.
Health care facilities are reminded of the importance of systematic implementation of infection prevention and control (IPC). Health care facilities that provide care for patients suspected or confirmed with MERS-CoV infection should take appropriate measures to decrease the risk of transmission of the virus to other patients, health care workers and visitors.
All Member States are reminded to promptly assess and notify WHO of any new case of infection with MERS-CoV, along with information about potential exposures that may have resulted in infection and a description of the clinical course. Investigation into the source of exposure should promptly be initiated to identify the mode of exposure, so that further transmission of the virus can be prevented.
WHO does not advise special screening at points of entry with regard to this event nor does it currently recommend the application of any travel or trade restrictions.
WHO has convened an Emergency Committee under the International Health Regulations (IHR) to advise the Director-General on the status of the current situation. The Emergency Committee, which comprises international experts from all WHO Regions, unanimously advised that, with the information now available, and using a risk-assessment approach, the conditions for a Public Health Emergency of International Concern (PHEIC) have not at present been met.
