Chikungunya and Dengue Fever outbreak in Dadaab Refugee Camp in Garissa County, March 2020

The index case of Chikungunya and dengue fever in Dadaab Refugee camp was reported on 23rd December 2019. As of February 27th 2020, a total of 207 suspected cases were line-listed. Out of 33 samples submitted for lab analysis, eleven (33.3%) were positive for CHIKV and another eleven (33.3%) for Dengue fever (DENV) by RT-PCR, and one suspected case died (CFR: 0.005%). Subsequently, Ministry of Health (MoH) through Kenya Field Epidemiology and Laboratory Training Programme (KFELTP) in collaboration with CDC and UNHCR mobilized a team to investigate the outbreak and assist with response and control efforts in the camp. Two Cohort 15 residents participated in the investigation. The investigation was conducted from 4th March to 14th March 2020.

An appropriate case definition and a questionnaire were drafted. An active case search and a retrospective review of health records and line-lists of the suspected CHIKV and DENV patients was conducted. The questionnaire was administered to residents of sampled households of suspected and confirmed cases.

Samples were collected from CHIKV/DENV suspected cases at IRC health facilities, centrifuged at the IRC health facility lab and serum samples collected and then transported to KEMRI laboratory in Nairobi for analysis. Results of the testing were then shared with IRC health manager who then updated the line-lists. The various stakeholders at Dadaab Refugee Camp discussed and agreed on the provision of support at the camp to mitigate future outbreaks.
