Some 226 sailors have been infected with the novel coronavirus. Some 147 sailors from the Navy's Welisara detachment were infected after they had conducted an operation to send drug addicts to quarantine on suspicion of being infected.
Another group of sailors had been infected after they went home on leave. This forced the government to cancel the leave of all security forces personnel to contain the spread of coronavirus.
Defense Ministry Secretary Kamal Gunaratne appealed to the public not to ostracise Naval personnel following complaints that sailors and their immediate families had been subject to condemnation.
Sri Lanka has been under a 24-hour curfew since March 20 to combat the deadly viral infection.
However, there has been intermittent lifting of the curfew in selected areas which were not seen as dangerous for the spread of the deadly virus.
