As part of the Health Ministry’s program of  increasing the number of PCR tests carried out to identify  COVID-19 infected persons, health authorities  took samples from 530 person from  the Peliyagoda  Fish Market on Wednesday , the largest number of samples taken from a single location so far.

The decision to test workers at the fish market was made after a fish vendor who had visited  there was confirmed as COVID-19 positive on Tuesday.

PCR tests are carried out in the country at the Medical  Research institute (MRI)  in Colombo while virology laboratories have been established the Kandy National Hospital and the teaching hospitals at Karapitiya and Anuradhapura thus decentralizing the PRC testing process.

The technique known as polymerase chain reaction  or PCR involves using swabs from the nose and  back of the throat. Results can take two to three days.
