Dire Dawa Health bureau reporting 3,756 cases with similar symptoms of the Chikungunya virus in the administration.
In a statement today the bureau said it is working to prevent the outbreak of Chikungunya in Dire Dawa.
Since the disease has similar symptoms with malaria and Dengue fever, the bureau did not confirm whether all the patients are affected with the Chikungunya virus.
Previously the disease was reported in Somali, Afar, and southern regions, according to Dr. Fuad Kedir, head of Dire Dawa Administration Health Bureau.
The bureau confirmed that four cases out of ten are infected with Chikungunya virus, said Fuad.
Chikungunya is a virus that causes high fever, headache, and joint and muscle pain for about three to seven days after a person is bitten by an infected mosquito.
Although most patients tend to feel better within days or weeks, some develop chronic joint pain and inflammation.
The disease rarely causes death, but joint pain can last months or even years for some people, according to the WHO.
