The next update will be issued on 27 September 2017

Disclaimer

Information provided herein is current as of the date of issue. Information added or changed since the last MERS-CoV situation update appears in red. Human cases are depicted in the geographic location of their report. For some cases, exposure may have occurred in one geographic location but reported in another. For cases with unknown onset date, reporting date was used instead. FAO compiles information drawn from multiple national (Ministries of Agriculture or Livestock, Ministries of Health; Centers for Disease Prevention and Control [CDC]) and international sources (World Health Organization [WHO], World Organisatwion for Animal Health [OIE]) as well as peer-reviewed scientific articles. FAO makes every effort to ensure, but does not guarantee, accuracy, completeness or authenticity of the information. The designation employed and the presentation of material on the map do not imply the expression of any opinion whatsoever on the part of FAO concerning the legal or constitutional status of any country, territory or sea area, or concerning the delimitation of frontiers.

 Situation in humans

  • Between 26 July 2017 and 30 August, thirty-four (n=34) new human cases have been reported in Saudi Arabia and one (n=1) in the United Arab Emirates, including seven fatalities (n=7) in Saudi Arabia. Since 2 August, a hospital cluster of possible human to human transmission was reported in Al-Jawf Province with 18 reported cases so far among patients, secondary household contacts and health care workers.

Figure 2. Breakdown of human MERS-CoV cases by potential source of exposure (in percent). Please note that while infection control improves in healthcare settings and history of animal contact is recorded more consistently in case investigations, the overall number of cases has decreased (see figure 1). The apparent increase in proportion of primary cases with animal exposure therefore should be interpreted in the overall context of a reduced human case count.

The role of domestic and wild animals, in particular dromedary camels and bats, and assess the likelihood of human exposure1 to MERS-CoV (i) through direct contact with these animals, (ii) while handling and consuming their products (milk, meat, urine) and (iii) from the environment at the animal-human interface (e.g. farms, households, slaughterhouses, markets, etc.) is evaluated in this qualitative release assessment.

 

 FAO and MERS-CoV

  • In close collaboration with OIE and WHO, monitoring the situation / inter-agency teleconferences;
  • Analysing available data, including results from surveillance in camels and advanced characterization of the virus;
  • Providing technical assistance and guidance to countries to improve understanding of the disease situation and help filling existing gaps in epidemiological knowledge;
  • Supporting national laboratories to develop capacity in serology and PCR diagnostic for MERS-CoV, quality assurance and quality control and biosafety, and establish national sample banks;
  • Keeping a dialogue between the scientific community and the field to ensure needs and gaps are addressed;
  • Assist in developing communication strategies to ensure appropriate information reaches the public on MERS-CoV and avoid possible negative impacts of the crisis on the livestock industry.

Country-level actions

Kenya

  • Longitudinal surveillance (cohort study) is ongoing at Soysambu Ranch in Nakuru County. Nine rounds of sampling have been conducted. Testing is ongoing at the country’s Central Veterinary Laboratories (CVL). 
  • Longitudinal surveillance (repeat cross sectional studies) has been initiated in Isiolo County; four rounds of sampling have been conducted so far and testing is ongoing at CVL.

Ethiopia

  • Camel and livestock sample collection and laboratory testing for MERS-CoV is underway in Somali, Afar, and Borena regions.

Egypt

  • Both longitudinal and cross sectional surveillance are scheduled to start by the 1st week of September.
  • For the cross sectional surveillance, samples will be collected form 46 villages and stored at the Animal Health Research Institute (AHRI) lab to be analysed up on receiving kits and reagents.
  • The first round of longitudinal surveillance (repeated cross sectional), will last for 2 weeks. The National Research Centre (NRC) team in collaboration with General Organization for Veterinary Services (GOVS) will collect samples from different nodes along camel value chain in Egypt.
