In a follow-up on the chikungunya outbreak in Dire Dawa, Ethiopia, health officials continues to see an increasing trend in cases since the end of July.
During the week ending September 8, officials saw an additional 7,264 new suspected cases from nine urban kebeles, or neighborhoods in Dire Dawa City Administration.
This brings the outbreak total to 31,147 to date.
Chikungunya Virus (CHIKV) is an arbovirus of the alphavirus genus (Togaviridae family) transmitted by the bite of infected Aedes mosquitoes. The word, Chikungunya, translates to “that which bends up”, based on the stooped position of patients during the rheumatic symptoms of the disease.
In humans bitten by an infected mosquito, the disease symptoms usually appear after an incubation period of three to seven days (range 1- 12 days).
CHIKV can cause acute, sub-acute, and chronic disease.
In acute disease, symptoms develop abruptly and include high fever, headache, myalgia and arthralgia (predominantly in limbs and large joints). The appearance of a maculopapular rash is also frequent. Severe forms of the disease are rare. Symptoms usually resolve in 7-10 days, although arthralgia and joint stiffness may persist intermittently for several months.
The disease shares some clinical signs with dengue and Zika, and can be misdiagnosed in areas where they are common. As there is no cure, treatment is focused on relieving the symptoms.
