Chikungunya Update for 14 July
• Since the last update of July 11, 2014, two new cases are under investigation for dengue and chikungunya. Both cases are from Savannah.
• Of the four cases investigated, three have tested positive, (two from Cayman Brac and one from George Town), one test result is negative (from George Town).
• All three cases are travel associated - travel history is to Guyana (2) and the Dominican Republic (1).
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
