AMSTERDAM — The European Center for Disease Prevention and Control (ECDC) maps which show levels of safety for countries during the COVID-19 pandemic has Greece in the “green” category, of low risk, with a positivity index under 4 percent.

Greece is in the top level in Europe in terms of testing (with more than 5,000 tests per 100,000 inhabitants), the EDCD said, although there are pockets with higher risk, the island of Kalymnos in lockdown.

In the composite index, which plots coronavirus cases over the previous 14 days, the rate of tests and positivity, Greece remains “orange,” with the Aegean and Ionian islands, as well as most of the Peloponnese “yellow,” it showed.

ECDC maps are based on data submitted by European Union member-states to the European System of Surveillance (TESSy) and are based on a two-week review in tracking the Coronavirus.

Greece is already allowing tourists from the European Union and United States and a handful of select countries if they can show proof of being vaccinated or a negative Coronavirus test, and will open further on May 15 for more countries.

The US State Department has warned Americans against coming for now though even as Greece's vaccination program is picking up and the United Kingdom – which won't allow people to travel until May 15 – has barred them from going to Greece apart from five islands although Greece has the UK on its safe list.
