The Greek island of Lesbos, which hosts over 15,000 asylum seekers, was added to a list of areas under “heightened” Covid-19 vigilance, AFP reported.

The move came as health authorities announced a new daily infection high of 284 cases nationwide in the last 24 hours.

The civil protection authority placed the Aegean island on a list of over a dozen other areas, including Athens, Thessaloniki and several tourist islands, with alarming infection clusters.

From Monday until September 1, Lesbos restaurants and bars must close at midnight and outdoor gatherings are limited to 50 people, except where social distancing rules are applied.
