Kenya: Rift Valley Fever Outbreak - Jun 2018

On 8 June 2018, the Kenya Ministry of Health reported an outbreak of Rift Valley fever (RVF) in Wajir County in the north-east of the country ...As of 8 June 2018, a total of 10 suspected RVF cases, including five deaths (case fatality rate 50%), have been reported in Wajir County. Three case-patients have since recovered and been discharged, while one remains in admission at Wajir County Referral hospital. Eight additional blood specimens have been obtained and are being analysed at the KEMRI. ([WHO, 8 Jun 2018](https://reliefweb.int/node/2647994))

The outbreak of Rift Valley fever (RVF) in Kenya continues to evolve, with two other counties reporting confirmed cases. Since our last report on 8 June 2018 (Weekly Bulletin 23), 44 additional cases with six deaths have been reported. Between 2 June and 21 June 2018, a cumulative total of 54 cases, with 11 deaths (case fatality rate 20.4%), have been reported from three counties: Wajir (25 cases, 6 deaths), Marsabit (28 cases, 4 deaths) and Siaya (1 case, 1 death) ... Kenya has recent experience dealing with RVF outbreaks. Strong prevention and response activities to this outbreak are being implemented, including ban on movement and slaughter of animals in the affected and at risk counties.

The RVF outbreak in Kenya has rapidly increased in the last week, with more cases reported. This outbreak is occurring among semi-nomadic and remote communities, who are largely dependent on their livestock for livelihood and as their main food source ... In addition, a number of the areas affected by RVF are experiencing outbreaks of other epidemic-prone diseases, along with major insecurity in some regions. These factors are of great concern as they could contribute to further spread of the disease in the subregion. There are already reports of an epizootic in Rwanda and suspected human cases in Rwanda and Uganda. ([WHO, 29 June 2018](https://reliefweb.int/node/2678874))

By early July, an outbreak of RVF, which affects both humans and livestock, was contained in Wajir and significantly reduced in parts of Mandera, but it is still ongoing in Mandera South, Marsabit (Moyale, North Horr, Saku, and parts of Laisamis sub-counties), and Isiolo (Sericho, Merti, and Oldonyiro wards). All livestock markets and slaughter houses in the affected areas remain closed in an effort to stop the spread of the disease, constraining a major source of pastoralists’ income. Widespread vaccination efforts continue, and alerts have been issued in neighbouring counties. ([FEWS NET, 25 Jul 2018](https://reliefweb.int/node/2712829))
