The restrictions were imposed in 31 provinces across the country and scaled up existing curbs, under which people under the age of 20 and over 65 have been told to stay at home.
Turkey has also halted all international flights, restricted domestic travel, closed schools, bars and cafes, and suspended mass prayers. But people have still been going to work to sustain economic activity.
Confirmed cases of COVID-19 increased by 4,747 and 98 people died in the last 24 hours, bringing the total death toll to 1,006.
Detailing specifics of the lockdown in a subsequent statement, the Interior Ministry said bakeries, pharmacies and health facilities would be among places excluded from the ban, enabling people to meet essential needs.
