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.

Ebola virus disease – Democratic Republic of the Congo - Thu, 03 Oct 2019 00:00:00 GMT

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.

Yellow fever – Nigeria - Thu, 26 Sep 2019 00:00:00 GMT

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.

Polio outbreak– The Philippines - Tue, 24 Sep 2019 00:00:00 GMT

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.

Ebola virus disease – Democratic Republic of the Congo - Thu, 12 Sep 2019 00:00:00 GMT

Ebola virus disease (EVD) transmission in the Democratic Republic of the Congo continued to ease this past week, with 40 new confirmed cases reported in North Kivu and Ituri provinces; this is the lowest weekly incidence since March 2019. While these signs are promising, it remains too soon to tell if this trend will persist. Emerging hotspots continue to pose challenges in terms of accessibility, insecurity, and violence. Surveillance indicators highlight that public health risks of further spread remain very high.

During the past 21 days (from 21 August through 10 September 2019), a total of 157 confirmed cases were reported form 15 health zones (Table 1, Figure 2), with the majority coming from the health zones of Kalunguta (19%, n=30), Beni (18%, n=28), Mambasa (16%, n=25), and Mandima (13%, n=20). Alimbongo, Oicha, and Pinga health zones recently passed 21 days without a new confirmed case of EVD.

Circulating vaccine-derived poliovirus type 2 – Republic of Ghana - Fri, 06 Sep 2019 00:00:00 GMT

In Nigeria and West Africa, a cVDPV2 outbreak originating from Jigawa state, Nigeria, continues to spread. In Ghana, cVDPV2 was isolated from an acute flaccid paralysis (AFP) case in Ando-Nyamanu, Chereponi district, Northern Region, bordering Togo. The case was a two-year old girl who had experienced onset of paralysis on 27 July 2019. Stool samples were taken on 27 and 28 July 2019, and sent to the National Polio Laboratory at the Noguchi Memorial Institute for Medical Research for further laboratory investigations. The sample tested positive for cVDPV2 on 17 August 2019. Sequencing of the sample from the AFP case revealed 25 nucleotide differences compared to the reference Sabin 2 and 6 nucleotides, with the closest sequencing match made with an AFP case originating from Jigsaw state, Nigeria from 2018. Earlier, a related cVDPV2 strain had been isolated from an environmental sample, collected on 11 June 2019, from Northern Region in Ghana. Both isolated viruses were linked to an outbreak originating in Jigawa, Nigeria, in 2018. In the past, this same strain had spread within Nigeria, and internationally to the Republic of Niger, Benin, and Cameroon.

The last indigenous wild poliovirus was reported in 2000. This is the first ever reported cVDPV2 outbreak reported in the country.

Circulating vaccine-derived poliovirus type 1 – Myanmar - Thu, 22 Aug 2019 00:00:00 GMT

On 23 June 2019, a vaccine-derived poliovirus type 1 (VDPV1) was isolated from a two -year- old child with acute flaccid paralysis (AFP), with onset of paralysis on 22 May 2019 from Kayin state, Myanmar. Subsequently, on 11 July 2019, a genetically linked VDPV1 was isolated from the same state from a 5-year 6-month-old child with AFP, with date of onset of paralysis on 14 June, and it was classified as circulating VDPV1 (cVDPV1) on 12 July 2019. On 25 July 2019, cVDPV1 was isolated from a third AFP case from the same state, with date of onset of paralysis on 23 May 2019. Subsequently, on 19 August 2019, a fourth case of VDPV1 has been confirmed in a six-year-old child, with onset of paralysis on 23 July 2019. The child has no history of vaccination with OPV. In addition, the virus has also been isolated from seven healthy community contacts. These linked viruses have 25 to 31 nucleotide changes from Sabin 1. All cases and contacts are from Hpapun township of Kayin state, Myanmar.

Myanmar’s routine immunization coverage is estimated at 91% for three doses of bivalent oral polio vaccine (bOPV) in 2018. Neighbouring countries including Thailand and other countries in South East Asia have been informed of the confirmed cVDPV1, and subnational surveillance is being strengthened across the region. In 2018, Myanmar and Kayin state met certification standards for AFP surveillance with non-polio AFP rate of 3.45, and stool adequacy rate of 100% for Kayin state.
