High alert over Dengue Fever as 150 cases diagnosed in Kenya's coastal region


A dengue fever outbreak has left more than 150 people infected in Kenya’s coastal county of Mombasa. The County Healthy Chief Officer Dr Khadija Shikely said the disease has spread and affected all the six sub counties with 119 cases confirmed in major private hospitals by Sunday.

“A total of 119 cases were confirmed by Rapid Diagnostic Test Kits in the major private hospitals, Aga Khan, Mombasa Hospital, Al Farouk, Jocham and Seyyid Fatima,” she said.

The county officers say the disease has hit the county and other surrounding counties but denied any deaths, unlike in 2014 when three patients succumbed to the disease, the Standard reports.

Heavy rains in the region are said to have created new breeding grounds for mosquitoes, which are the vectors transmitting the disease to humans.

It is transmitted by female mosquitoes mainly of the species Aedes aegypti and, to a lesser extent, Ae. albopictus. This mosquito also transmits chikungunya, yellow fever and Zika infection. Dengue is widespread throughout the tropics, with local variations in risk influenced by rainfall, temperature and unplanned rapid urbanization, according to the World Health Organisation.
