First Case of Chikungunya Confirmed in NC

RALEIGH, N.C. : June 12th, 2014 - North Carolina's first case of chikungunya was confirmed in a resident who recently travelled to the Caribbean. Chikungunya virus is transmitted through the bite of an infected mosquito, and the Asian Tiger mosquito that is commonly found in North Carolina could effectively transmit this virus. At this time, there have not been any cases of the disease known to have been acquired in North Carolina or the continental United States.
Symptoms of chikungunya usually begin three to seven days after being bitten by an infected mosquito. Symptoms typically include the sudden onset of fever and severe, often disabling, joint pains in the hands and feet. Many patients feel better within a week; however, the joint pain may persist for months in some people. Newborns exposed during delivery, adults over 65 years and people with chronic medical conditions have a greater risk for a severe form of the disease.
Prior to its introduction in the Caribbean, chikungunya was established in East Africa, India, the Indian Ocean and the Western Pacific regions. It was introduced in the Caribbean in December 2013 through travelers returning from affected areas. As of June 6, chikungunya has caused illness in over 130,000 persons in the Caribbean.
North Carolina’s first case of chikungunya was confirmed in a resident who recently travelled to the Caribbean in  June 2014, thought it has been determined that there is a low risk of transmission of chikungunya to the local mosquito population. A probable case had been reported in 2013 after returning from India. 
There is currently no evidence that any mosquitoes in North Carolina carry the chikungunya virus. There is also no current evidence that any mosquito carrying chikungunya virus is present in the continental United States.
DHHS' Division of Public Health advises persons traveling to countries where chikungunya transmission is occurring to:
• Take personal precautions to prevent mosquito bites; and
• Immediately consult a medical provider if they develop fever in the two weeks after their return home.
There is no vaccine to prevent chikungunya.
• Most people infected with chikungunya virus will develop some symptoms.
• Symptoms usually begin 3–7 days after being bitten by an infected mosquito.
• The most common symptoms are fever and joint pain.
• Other symptoms may include headache, muscle pain, joint swelling, or rash.
• Chikungunya disease does not often result in death, but the symptoms can be severe and disabling.
• Most patients feel better within a week. In some people, the joint pain may persist for months.
• People at risk for more severe disease include newborns infected around the time of birth, older adults (≥65 years), and people with medical conditions such as high blood pressure, diabetes, or heart disease.
• Once a person has been infected, he or she is likely to be protected from future infections.
• The symptoms of chikungunya are similar to those of dengue, another disease spread by mosquitoes.
• See your doctor if you develop the symptoms described above.
• If you have recently traveled, tell your doctor.
• Your doctor may order blood tests to look for chikungunya or other similar diseases.
• There is no medicine to treat chikungunya virus infection or disease.
• Decrease the symptoms:
- Get plenty of rest
- Drink fluids to prevent dehydration
- Take medicines, such as ibuprofen, naproxen, acetaminophen, or paracetamol, to relieve fever and pain.
"With North Carolina residents traveling to and from the Caribbean and other affected areas, we have been monitoring for possible imported cases," said Dr. Megan Davies, DHHS' State Epidemiologist. "Anyone experiencing symptoms of chikungunya should contact a physician and minimize exposure to mosquitoes to reduce the risk of transmitting the virus to others. Travelers who visit countries where chikungunya is widespread should take extra precaution against mosquito bites."
To protect yourself and your family against mosquito bites:
• Wear light-colored long pants and long-sleeved shirts.
• Reduce time spent outdoors, particularly during early morning and early evening hours when mosquitoes are most active.
• Apply EPA-approved mosquito repellents such as DEET, picardin, oil of lemon eucalyptus or IR3535 to exposed skin areas.
• Always follow guidelines when using mosquito repellent.
• Since mosquitoes may bite through thin clothing, spray clothes with repellent containing permethrin or another EPA-registered repellent will give extra protection.
DHHS' Division of Public Health strongly recommends that all North Carolina residents take measures to decrease environmental conditions favorable to breeding for the species that could transmit this infection, the Asian Tiger mosquito. This mosquito is an aggressive daytime biter, breeds in small water containers and does not travel long distances. To reduce mosquito breeding areas around your home:
• Remove any containers that can hold water;
• Change the water in bird baths and pet bowls frequently and repair leaky outdoor faucets;
• Cover rain barrels with tight-fitting screens or lids;
• Keep gutters clean and in good repair; and
• Use screened windows and doors and make sure screens are not torn and fit tightly.
