Public health response
The country has activated the national task force to coordinate the outbreak response activities. Since January 2017, WHO and other partners have been providing technical support to the country to control of the outbreak. Following the development of the national response plan, WHO and other partners supported the country to scale-up the outbreak response activities such as surveillance, case management, and social mobilization. This was also coupled with the improvement of food hygiene standards and promotion of safe food handling, besides scaling-up Water, Sanitation, and Hygiene (WASH) related activities. This resulted in a decline in the number of cholera cases.
WHO risk assessment
Despite the decline in the number of cases reported, the outbreak appears to be clustered around two major types of settings. First, the refugee camps particularly Kakuma and Dadaab, and second in the populous Nairobi capital county. Both settings are concerning, considering the overcrowded conditions and limited access to care in the first setting, and the high population density in the second setting. This could enable the spread of the outbreak to other districts. Also, previous outbreaks have shown that cases increase during the rainy season, which has started recently.
In addition, various physical, social, political, and environmental factors increase the vulnerability and the susceptibility of the country’s population to the cholera outbreaks. These include regional drought, conflict, and insecurity in the Horn of Africa, and the increased movement within and to the country by people fleeing conflicts in Somalia and South Sudan.
Overall, the risk of the current outbreak is assessed as high at the national level and low at the regional and global levels.
WHO recommends proper and timely case management in cholera treatment centres. The affected communities should have improved access to water, effective sanitation, proper waste management, and enhanced hygiene and food safety practices. Key public health communication messages should be provided. WHO encourages travellers to the affected area to take proper hygiene precautions to prevent potential exposure.
WHO does not recommend any restriction on travel and trade to Kenya based on the information available on the current outbreak.
