ATHENS — Three asymptomatic migrants that landed on the shores of Lesvos have tested positive for the Covid-19 coronavirus, authorities on the island announced on Sunday. The three cases were among a total of 36 migrants – 15 men, 10 women and 11 children from Iran and Afghanistan – that were rescued by coast guard officers on June 13 and taken to the port of Petra, where they were temporarily detained.

In testing when the group first arrived, only one migrant had tested positive for the virus but the group was placed in quarantine at the Megala Therma facility, while the coast guard officers and all others that came into contact with them tested negative. In a repeat round of tests, the original case tested negative but three others tested positive for the virus, though without symptoms, and the quarantine for the group has been extended for another fortnight, while the three patients have been transferred elsewhere and will be held separately.
