WHO disease outbreak news
  1. From 1 through 30 September 2019, the National IHR Focal Point of Saudi Arabia reported 4 additional laboratory-confirmed cases of Middle East respiratory syndrome (MERS-CoV) infection and one associated death. The cases were reported from Al-Qassim (2 cases), Riyadh (1 case), and Al-Ahsaa (1 case) regions.

    The link below provides details of the 4 reported cases:
  2. The number of confirmed cases of Ebola virus disease (EVD) has been relatively low in recent weeks, with 15 new confirmed cases reported in North Kivu and Ituri provinces during the epidemiological week of 7 October through 13 October (Figure 1).
  3. On 8 September, Sudan’s Federal Ministry of Health (FMoH) notified WHO about a cholera outbreak in four localities in the Blue Nile State (BNS), south-eastern Sudan, bordering Ethiopia and South Sudan. The first case was detected on 28 of August 2019.

    From 28 August through 12 October 2019, a total of 278 suspected cholera cases, including 8 deaths (case fatality ratio: 2.88 %), have been reported from four localities in Blue Nile State including Al Roseries (113), Ad Damazin (55), Wad Almahi (3) and Baw (5), and five localities in Sinnar State including Abu Hugar (80), Singa (4), Alsoky (14), Aldaly wa Almzmom (3) and Sennar (1) . One hundred seventy two cases were female (62%), and 238 (93.1%) were over 5 years of age.
  4. The number of reported cases of Ebola virus disease (EVD) consistently declined in recent weeks, with 14 new confirmed cases reported in North Kivu and Ituri provinces during the epidemiological week of 30 September through 6 October (Figure 1).
  5. On 29 August 2019, a suspected yellow fever case was reported from Kano state with a travel history to Yankari game reserve, Alkaleri Local Government Area (LGA), Bauchi state, Nigeria.

    From 29 August through 22 September 2019, Nigeria reported an outbreak of yellow fever with an epi-centre in the Yankari game reserve of Alkaleri LGA, Bauchi state. According to Nigeria Centre for Disease Control (NCDC), 231 suspected cases have been reported in four states including Bauchi (110), Borno (109), Gombe (10), and Kano (2), of which there have been 13 presumptive positive by IgM testing and 24 cases positive by reverse-transcriptase polymerase chain reaction (RT-PCR) at national laboratories. Of 24 cases confirmed by RT-PCR (20 cases in Bauchi, three in Gombe and one in Kano state), six deaths were reported, all from Alkaleri LGA, Bauchi state, resulting in a case fatality ratio of 25% among the confirmed cases. The vaccination history for the 231 suspected yellow fever cases is not known, and the results of follow-up testing from regional reference laboratory Institute Pasteur Dakar (IPD) are not yet available.
  6. The Ebola virus disease (EVD) outbreak in the Democratic Republic of the Congo continues this week with 20 new confirmed cases reported in North Kivu and Ituri provinces from 25 September-1 October 2019, versus 29 in the previous week.
  7. On 16 July 2019, the Ebonyi State Ministry of Health received information about suspected yellow fever cases in Ndingele ward, Izzi Local Government Area (LGA), Nigeria. The cases had symptoms of fever and jaundice, reported with onset since May 2019. As of 30 August 2019, a total of 84 suspected yellow fever cases, including 26 deaths (case fatality ratio: 31 %), have been reported across nine LGAs within Ebonyi State. Of the suspected yellow fever cases, fifty-five per cent (46/84) are male. The most affected age group is 0-9 years (28 cases, 33%), followed by age groups 20-29 years and above 30 years each with 20 cases (24%). The 10-19 year age group has the least number of cases (16 cases, 19%). Seventy-nine per cent of suspected cases (66/84), including seven confirmed cases positive by real-time polymerase chain reaction (RT-PCR) are reported from Izzi LGA which is located in the north-eastern part of the State, bordered with Cross River State in the east, and Benue State in the north. One case has been confirmed in an international worker involved in the extractive industry in Izzi LGA, and residing in adjacent Abakiliki LGA (an urban centre in the State).

    The assessment conducted by the LGA rapid response team (RRT) and national agencies found low vaccination coverage and poor routine immunization documentation. Community surveys were conducted and yellow fever vaccination coverage was estimated to be 56% (64% for children aged less than 5 years and 48% for those older than 5 years of age). Though Nigeria introduced routine vaccination for yellow fever into the immunization schedule in 2004, most adults remain susceptible and overall population immunity is low. Although no entomological studies were conducted at the time, the geography and vegetation of the affected state is compatible with the presence of the Aedes mosquitoes, as illustrated by the transmission patterns.
  8. From 1 through 31 August 2019, the National IHR Focal Point of Saudi Arabia reported 6 additional laboratory-confirmed cases of Middle East respiratory syndrome (MERS-CoV) infection and one associated death. The cases were reported from Riyadh (3 cases), Taif (1 case), Quriyat (1 case), and Najran (1 case) regions. One of the cases reported (Case #4) is a household contact identified during the contact tracing investigation of Case #2.

  9. The Ebola virus disease (EVD) outbreak in the Democratic Republic of the Congo continues this week with 29 new confirmed cases reported in North Kivu and Ituri provinces from 18-24 September 2019, versus 57 in the previous week.
  10. On 19 September 2019, the Philippines declared an outbreak of polio. Two cases have been reported to date, both caused by vaccine-derived poliovirus type 2 (VDPV2). Environmental samples taken from sewage in Manila on 13 August and a waterway in Davao on 22 August have also tested positive for VDPV2.

    The first case was confirmed on 14 September following testing by the National Polio Laboratory at the Research Institute for Tropical Medicine, the Japan National Institute of Infectious Diseases (NIID) and the United States Centers for Disease Control and Prevention (CDC). The case-patient is a 3-year-old girl from Lanao del Sur in the southern Philippines. The virus isolated is genetically linked to VDPV2 previously isolated from environmental samples in Manila and Davao. This indicates that the virus is circulating.
