Public Health officials are presently testing two blood samples to rule out dengue and/or chikungunya.Officials say the symptoms presented are not classical of either illness but that the tests were done as a routine.This news follows the confirmation on 30 June 2014, of the first imported case of chikungunya in the Cayman Islands.Both dengue and chikungunya are transmitted by Aedes aegypti mosquitoes. Symptoms of dengue include fever, headache, muscle aches, joint pains, pain behind the eyes, and rash.  Among chikungunya symptoms are fever, joint pains, muscle pain, headache, nausea, fatigue and rash.While joint pain is predominant in chikungunya, as muscle pain is in dengue, both illnesses share some clinical signs that can be misdiagnosed. For this reason, patients with these symptoms are investigated for both dengue and chikungunya. The Caribbean Public Health Agency (CARPHA) also tests, blood samples for both viruses.When travelling to countries with dengue and chikungunya virus, persons should use insect repellent containing DEET, wear long sleeves and pants, and stay in places with air conditioning, or that have window and door screens.
