Keeping Dengue in Check
With the incidence of dengue fever rising sharply in the Caribbean, Cayman's public health officials are closely monitoring for local presence of the disease.
"Although we had three confirmed cases reported in January this year, there have been no other dengue cases reported since then and the Cayman Islands is still considered to be dengue free. However, especially with the regional outbreak in mind, we are not complacent and medical personnel are on high alert to look for any local cases," Medical Officer of Health Dr. Kiran Kumar said.
Currently dengue outbreaks are reported in some countries in the Caribbean and Central America like Honduras, Belize, Puerto Rico, and Trinidad and Tobago.
"Dengue fever is caused by a virus, but a mosquito biting a person with dengue fever can spread the virus to another person. Hence persons, who develop symptoms within two to three weeks of having returned from countries with dengue cases, are advised to consult their physician," Dr. Kumar explained.
The symptoms of dengue are high fever, severe headache, backache, joint pains, nausea and vomiting, eye pain, and rash.
The incubation period (the time that the infection takes to develop before it shows symptoms) is usually four to seven days; but can be up to three weeks.
There is no vaccine or specific medication to treat dengue infection, and people travelling to known dengue endemic countries should take preventative measures such as using a repellent, wearing protective clothing, using air conditioning indoors or only opening screened windows and doors, and staying indoors during early dawn and dusk when mosquitoes are most active.
Even as there are no local cases of dengue fever, the dengue carrier - the Aedes aegyptii mosquito - is present in the Cayman Islands, making transmission of the disease possible. "The only real protective measure is avoiding mosquito bites," Dr. Kumar said.
Upon report of a suspected dengue case the Public Health Department would immediately inform its partners in prevention and control the Mosquito Research and Control Unit (MRCU) and the Department of Environmental Health (DEH) of the suspected case, and they would take measures as if it was a case of dengue fever and enhance their mosquito control measures around the residence of the case.
For more information, call the Public Health Department on 244-2648 or 244-2621, or Faith Hospital on 948-2243.
For advice on mosquito control measures contact the MRCU on 949-2557 or DEH on 949-6696 in Grand Cayman or 948-2321 in Cayman Brac.
