All Cayman Islands prisoners will be tested as part of the new strategy of testing people who do not have symptoms and are not believed to have the virus.
Frontline health workers and in-patients at hospitals will also be part of the first wave of tests.
Dr. John Lee, Cayman’s chief medical officer, said hundreds of people would be swabbed and tested, adding that this would help determine if the virus had spread throughout the community.
Various strategies are being considered as testing progresses, including possible random sampling throughout the entire population.
Lee said the screening tests would be treated and reported as a distinct group and would give a better idea of the prevalence of the virus in the Cayman Islands.
He said these tests had begun already and around 400 samples had been taken. He expects well over 1,000 people to be tested in the next two weeks.
“It was started last week,” he said. “There are several hundred tests going through the system.”
Lee said there were no new results to announce Tuesday as the testing machines were undergoing routine maintenance.
The first results from the screening tests will be announced later this week.
Cases linked to people who have travelled or are connected to people who have previously tested positive will be treated as a separate category for reporting purposes.
Premier Alden McLaughlin said the testing programme would be critical to determining if the coronavirus had spread throughout the community.
Only when those results are analysed, he said, could authorities consider lifting restrictions.
“By this time next week, we will have a very good idea of the prevalence of this virus in the community. I remain hopeful that we are not into sustained community transmission,” he added.
“I just ask everyone to remain patient. I know it is very stressful and it is very frustrating but it would be a mistake if all the efforts and all the sacrifices and frustrations we have gone through were to be for naught because we made the wrong decision at the wrong time to start opening up the community.”
He said testing people without symptoms – healthy people who are in the workforce – was the only way to get a clear idea of the likely incidence of the virus in the broader community.
