Additional information on the outbreak in the Republic of Korea
To date, a total of 186 MERS-CoV cases, including 33 deaths, have been reported. One of the 186 cases is the case that was confirmed in China and also notified by the National IHR Focal Point of China.
The median age of the cases is 55 years old (ranging from 16 to 87 years old). The majority of cases are men (59%). Twenty-six cases (14%) are health care professionals. To date, all cases (excluding the index case) have been linked to a single chain of transmission and are associated with health care facilities.
Detailed information concerning MERS-CoV cases in the Republic of Korea can be found in a separate document (see related links).
Public health response
The government of the Republic of Korea continues to implement intense case and contact management activities. As of 7 July, 674 contacts are being monitored while a total of 15,669 contacts have been released. New contacts continue to be added on a daily basis as they are identified.
Globally, since September 2012, WHO has been notified of 1,367 laboratory-confirmed cases of infection with MERS-CoV, including at least 487 related deaths. *
Based on the current situation and available information, WHO encourages all 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 health care 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, health-care 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 MERS‐CoV infection. General hygiene measures, such as regular hand washing, should be adhered to.
WHO remains vigilant and is monitoring the situation. Given the lack of evidence of sustained human-to-human transmission in the community, WHO does not recommend travel or trade restrictions with regard to this event. Raising awareness about MERS-CoV among travellers to and from affected countries is good public health practice.
Public health authorities in host countries preparing for mass gatherings should ensure that all recommendations and guidance issued by WHO with respect to MERS-CoV have been appropriately taken into consideration and made accessible to all concerned officials. Public health authorities should plan for surge capacity to ensure that visitors during the mass gathering can be accommodated by health systems.
Disease Outbreak News concerning MERS-CoV in the Republic of Korea will be published on a bi-weekly basis (on Tuesdays and Fridays). Due to the magnitude of the current outbreak, DONs will focus on describing the evolution of the outbreak and epidemiological trends, instead of focusing on individual case details.
