The prison in the twin-isle nation of Antigua and Barbuda is currently under lockdown after 23 inmates and four officers test positive for Covid.
The numbers are expected to increase as testing is still ongoing.
Superintendent of the prison Colonel Trevor Pennyfeather told reporters over the weekend that the cases started to show up on Saturday.
Medical officials have been at the prison conducting testing ever since.
About 42% of the entire prison population have already been tested according to the prison boss, who claimed that the symptoms experienced by those who tested positive have been relatively mild.
He also claimed that some prisoners are apprehensive about getting tested.
Those who tested positive have been isolated and everyone is being administered pharmaceuticals to reduce the symptoms.
“We are treating everyone as if they have the virus because there are some people who refused to get tested. So we are ensuring they have the required vitamins and those with a fever are receiving paracetamol,” he said.
This is the second time since the pandemic that there has been an outbreak at the prison in Antigua and Barbuda.
