(CMR) The Ministry of Health & Wellness and the Public Health Department said there may be early evidence of local person-to-person Dengue transmission identified within the Cayman Islands.
“While previously confirmed cases of Dengue were linked to individuals with a travel history, new evidence has identified that local transmission- meaning passed from an individual within the Cayman Islands to a different person within the Cayman Islands with no travel history- has occurred,” explained Chief Medical Officer, Dr. Nick Gent.
For the reason that starting of 2023, 28 cases of Dengue have been investigated locally, with 4 cases confirmed, three with travel history, and 1 with no travel history.
“Up to now, we have now had one confirmation of an individual with no travel history, but I caution that this a disease where there could be quite a lot of asymptomatic cases, so we are going to remain vigilant and can proceed our efforts to coach the general public on methods to protect themselves while taking measures to regulate the mosquito population,” Dr Gent added.
Typically, there are between 0-8 confirmed Dengue cases annually within the Cayman Islands, with the exceptions being an outbreak in 2012 where there have been 37 cases confirmed (18 imported and 19 locally transmitted), and one other outbreak in 2019, 24 cases confirmed (3 imported and 21 locally transmitted). It is crucial to notice that Cayman now has local testing capability for Dengue on the Cayman Islands Molecular Biology Laboratory (CIMBL), putting it in a a lot better position than it has been in previous years by eliminating the necessity to send samples overseas for confirmation.
“These limited outbreaks within the last twenty years have happened after the introduction of the disease into the Cayman Islands, and aggressive mosquito control measures targeting the Aedes mosquito -which is answerable for the person-to-person transmission of the disease- were quite effective,” explains Medical Officer of Health, Dr. Samuel Williams-Rodriguez.
Energetic surveillance and continued liaison between the Public Health Department and Mosquito Research and Control Unit (MRCU) to take vector control measures each time a suspected case is reported is ongoing.
Dr. Williams-Rodriguez also emphasized that to ensure that the Aedes mosquito to transmit Dengue, they need to bite infected individuals.
“For Aedes mosquitoes to transmit dengue, they need to bite infected individuals; otherwise, they’ll’t turn into infectious and transmit the disease. Dengue fever is attributable to a virus, but a mosquito biting an individual with Dengue can spread the virus to a different person.” Dr. Williams-Rodriguez added.
“Hence, individuals who develop Dengue symptoms inside two to 3 weeks of getting back from countries with Dengue cases are advised to seek the advice of their physician and inform them of their travel history,“ he continued.
The very best technique to prevent the transmission of Dengue fever is by stopping mosquito bites.
“I encourage residents to familiarise themselves with the general public health advice for travel and native prevention. And, as at all times, early diagnostic testing is paramount, so if showing symptoms, please contact your physician or the Public Health Department on 244-2648,” Dr. Gent said.
