Between October 18 and October 26, 2014, the National IHR Focal Point of Saudi Arabia (KSA) notified the World Health Organization (WHO) of 12 additional cases of Middle East respiratory syndrome coronavirus (MERS-CoV) infection, including five deaths.
The cases are from Taif (6), Riyadh (4), Madinah (1) and Skaka (1). The median age of the patients is 54 years old (ranging from 17 to 75 years old). Nine cases (75 percent) are men and 10 (83 percent) are Saudi nationals. Ten patients (83 percent) suffer from one or more comorbidities. None of the cases has a history of contact with camels nor of raw camel products consumption; however, two of the patients (17 percent) live in areas densely populated with camels. In the 14 days that preceded the onset of symptoms, none of the cases performed Umrah/Hajj and only two (17 percent) traveled out of their cities of residence. Eight patients (67 percent) came in contact with laboratory-confirmed MERS-CoV cases.
Tracing of household contacts and healthcare contacts is ongoing for these cases.
The National IHR Focal Point of Saudi Arabia also notified WHO of the death of a MERS-CoV case that was initially reported on Oct. 6, 2014.
Globally, WHO has been notified of 897 laboratory-confirmed cases of infection with MERS-CoV, including at least 325 related deaths.
Based on the current situation and available information, WHO encourages all of its member states to continue their surveillance for acute respiratory infections and to carefully review any unusual patterns.
Infection prevention and control measures are critical to prevent the possible spread of MERS-CoV in healthcare facilities. It is not always possible to identify patients with MERS-CoV early because like other respiratory infections, the early symptoms of MERS-CoV are non-specific. Therefore, healthcare workers should always apply standard precautions consistently with all patients, regardless of their diagnosis. Droplet precautions should be added to the standard precautions when providing care to patients with symptoms of acute respiratory infection; contact precautions and eye protection should be added when caring for probable or confirmed cases of MERS-CoV infection; airborne precautions should be applied when performing aerosol generating procedures.
Until more is understood about MERS-CoV, people with diabetes, renal failure, chronic lung disease, and immunocompromised persons are considered to be at high risk of severe disease from MERSCoV infection. Therefore, these people should avoid close contact with animals, particularly camels, when visiting farms, markets, or barn areas where the virus is known to be potentially circulating. General hygiene measures, such as regular hand washing before and after touching animals and avoiding contact with sick animals, should be adhered to.
Food hygiene practices should be observed. People should avoid drinking raw camel milk or camel urine, or eating meat that has not been properly cooked.
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.
