An Allen County resident, who recently traveled to the Caribbean, has tested positive for the Chikungunya virus. Transmitted by mosquitoes, Chikungunya has been found in multiple Caribbean countries, said Ken Severson, Indiana State Department of Health spokesman.
Cases have been identified in travelers returning from the Caribbean and local transmission has not been identified in the United States. Chikungunya has also been found in Africa, Asia and islands in the Indian Ocean and Western Pacific areas.
“We expected the epidemic in the Caribbean to cause some travel-related cases here in Indiana,” said Jennifer Brown, DVM, ISDH public health veterinarian. While the Chikungunya risk for Hoosiers who have not traveled to the Caribbean is low, state health officials give this advice to protect against mosquito-borne viruses like West Nile virus and St. Louis encephalitis:
• Avoid places where mosquitoes are biting;
• Apply insect repellent containing DEET, picaradin or oil of lemon eucalyptus to clothes and exposed skin;
• Install or repair screens on windows and doors to keep mosquitoes out of the home; and,
• When possible, wear pants and long sleeves, especially if walking in wooded or marshy areas.
“Chikungunya is just another example of the dangers posed by disease-carrying mosquitoes,” said Allen County Health Commissioner Deborah McMahan, M.D. “Whether you are planning a trip to the Caribbean or a picnic in your own backyard, please remember your best defense is to wear insect repellent and stay inside as much as possible during peak biting times.”
Most people exposed to Chikungunya will develop symptoms. The virus does not often cause death, but the symptoms can be severe. The most common symptoms are high fever and severe joint pain. Others may include headache, muscle pain, joint swelling or rash. Most patients feel better within one week, but the joint pain can persist for months in some cases. People who develop these symptoms should contact a health care provider immediately.
