Rift Valley fever outbreak reported in Kenya
A Rift Valley fever (RVF) outbreak in Kenya that began in the middle of November has led to 21 infections, 9 of them fatal, the World Health Organization (WHO) African regional office said yesterday in its weekly outbreaks and health emergencies report.
All of the patients are male cattle herders between ages 13 and 70 years old. Of the 21 cases, 4 are lab confirmed and 17 are listed as suspected. Two neighboring counties in the east central part of the country are affected, Isiolo and Garissa.
Outbreaks in animals have occurred at the same time, and tests on sheep and one camel were positive for RVF. Livestock movement controls have been established in the affected area, and animal vaccination is planned. Efforts are under way to assess the extent of the outbreak in humans and to teach health workers and veterinarians about the disease.
The virus that causes RVF is spread by mosquitoes and mainly affects livestock, though it can cause severe infections in people. The WHO noted that heavy rains and flooding contributed to the latest outbreak by increasing the number of vectors. Kenya reported its last RVF outbreaks in 2014 and 2018.
