The first cases of Chikungunya were reported in mid-February 2022 in Kotulo within Wajir County. Between February 10th and 24th, 23 samples from the suspected cases were collected and analyzed at KEMRI Nairobi laboratory, out of these, five samples tested positive for the Chikungunya virus, this is from the Ministry of health rapid assessment report. A rapid assessment team by MoH and County Government was deployed to the affected area by the Wajir county department of health. The team visited 50 households from different villages that were suspected to be having patients suffering from Chikungunya. The team identified 16 patients with symptoms of Chikungunya disease. The 15 samples were sent to the KEMRI laboratory for investigation. The team has since line-listed a total of 67 cases in which five are confirmed and 53 are probable cases in which most of the cases are epidemiologically linked to the confirmed cases from MoH/KEMRI above. Wargadud Ward in Tarbaj Sub-County is the ward affected by those potential cases. (IFRC, 23 Mar 2022)
