OMAHA, Neb. (KMTV) - Nebraska has a confirmed fourth case of a mosquito-borne virus called chikungunya in Douglas County.
Douglas County Health officials say a man over the age of 50, who recently traveled to Puerto Rico, contracted the disease.
“The infection was acquired while traveling, and there will continue to be a risk for people who travel to areas where this disease has been found,” said Douglas County Health Director Dr. Adi Pour in a statement Friday.
The Centers for Disease Control and Prevention says the most common symptoms are fever and joint pain.
Below are some facts about chikungunya from the health department:
- Chikungunya has been found in Africa, Asia, Europe, islands in the Indian and Pacific Oceans, the Caribbean, and in countries and territories in Central and South America.
- The disease is spread through mosquito bites. Aedes species mosquitoes usually transmit chikungunya. They mostly bite in the daytime.
- Chikungunya has not been found in mosquitoes in the U.S. according to the CDC.
CDC studies showed an average of 28 people in the U.S. per year tested positive for chikungunya from 2006-2013. All were travelers visiting or returning to the U.S. from affected areas.
- So far in 2014, there have been 27 chikungunya cases in nine states. All were travel-associated cases.
- The most common chikungunya symptoms are fever and severe joint pain, often in hands and feet. Other symptoms may include headache, muscle pain or rash. Symptoms usually start within a week of being bitten by an infected mosquito.
- There is no medication to treat or prevent chikungunya. Some medicines help reduce fever and pain. Patients recover in about a week, but long-term joint pain occurs in some people.
