Greece confirmed 1,410 new COVID-19 infections in 24 hours, the National Public Health Organization (EODY) said on Friday.
There were no infections identified during the checks at entry points to the country, it added.
All confirmed COVID-19 cases in Greece total 170,244.
Of these, 6,086 are linked to travel abroad and 54,695 to already confirmed cases.
A total of 293 people are intubated in hospitals. Their median age is 70 years, 86.3 percent have an underlying condition or are aged 70 or more, and 213 are men.
Since the start of the pandemic, 1,204 have been discharged from Intensive Care Units.
EODY also announced 21 new deaths due to COVID-19 in Greece.
As of the pandemic's outbreak in Greece, 6,077 people have lost their lives due to the COVID-19.
Their median age was 79 years, and 95.6 percent had an underlying condition and/or were aged 70 or more.
Of the deceased, 3,574 were men.
Deputy Minister for Civil Protection Nikos Hardalias said on Friday that health authorities recorded 95 new infections in Achaia on Friday and in 56 in Evia, while the two regions have a total of 732 and 501 active infections, respectively.
This means that schools and all non-essential stores will close. The minister did not specify the duration of the lockdown, but tougher restrictions imposed on other regions will last until the end of the month.
The move was widely expected following a relevant recommendation by the committee of experts which convened earlier in the day.
Hardalias said the island of Skyros, which is part of the regional unit of Evia, is excluded from the additional restrictions.
Three more municipalities are currently in the “red” in terms of infections: Aghios Nikolaos in Crete, Santorini and Mykonos.
