Chik V & Dengue Update for 8 Dec
• During the week of 2 December - 8 December 2014 the Cayman Islands received 10 results for pending samples from the Caribbean Public Health Agency. Six were negative and four positive where the newest cases are from: Bodden Town – two, George Town – one, West Bay – one.
• Of these positive results, onset of symptoms was September (1) October (2) November 7th (1), which means that the persons are no longer contagious.
• Two had travel history to Jamaica whilst one had travel history to Puerto Rico and one had no travel history, indicating local transmission. Such reported cases are due to the lag between the instatement of the CARPHA policy and the pending results with travel history.
• This brings the number of locally transmitted cases to 14.
• The total number of laboratory confirmed chikungunya cases in the Cayman Islands to date is 41. Another possible 27 cases had travel history to endemic areas. As per CARPHA guidelines, blood samples for suspected cases with travel history to endemic areas are no longer being sent for testing, but are considered possible cases.

• The total number of confirmed dengue cases remains at four.
• Distribution of confirmed cases: George Town – one; West Bay- one and Bodden Town – two. The two cases in Bodden Town are locally acquired.
• Chikungunya causes fever, severe joint pain, muscle pain, headache, nausea, fatigue and rash.
• Dengue causes high fever, severe headache, severe pain behind the eye, muscle and joint pains, nausea, vomiting, swollen glands or rash.
• As both chikungunya and dengue are transmitted through the bite of an infected Aedes aegypti mosquito, protection from mosquito bites is the only prevention.
• Use mosquito repellent with DEET on the skin, and wear long sleeve pants and shirts when outside during times that mosquitoes bite, whether in the Cayman Islands or on travels.
