Trinidad: Experts baffled with new covid19 infections

Medical experts are trying to understand an aspect of the epidemiology of the coronavirus, as three of the latest confirmed cases tested positive long after the 14-day incubation period, and none of the three had any symptoms.

Three of the four patients to test positive were among 68 cruise ship passengers who were put in isolation at a facility at Balandra on March 18 after their return to TT.​

They had all previously tested negative for the virus and were being readied to be sent home. ​

Speaking at a media conference on Sunday, Chief Medical Officer Dr Roshan Parasram described the most recent infections as “quite unusual,” as the coronavirus was originally thought to have an incubation period of only 14 days.​

In this case, the three most recent cases tested positive after being kept in isolation for 24 days. ​

He said information was forwarded to virologists at the Caribbean Public Health Agency (CARPHA) to try to explain the apparent change in the behaviour of the disease.​

Parasram said one of the most recent cases was the wife of a confirmed coronavirus patient, and suggested she may have contracted the disease by being in close contact with him, but could not explain the source of the other two infections.​
