The daily coronavirus cases hit a record of nearly 50,000 in Turkey on Tuesday.
The Health Ministry reported 49,685 confirmed single-day cases. The number of daily deaths also reached the highest level this year, with 211 confirmed in the past 24 hours.
Infections in this country of 84 million have surged since the government eased restrictions at the start of March.
Last week, President Recep Tayyip Erdogan announced renewed weekend lockdowns and the closure of cafes and restaurants for all but take out service during the Islamic month of Ramadan, which begins on April 13.
However, health groups say the measures are not strong enough to stem the spike.
About 75% of the infections in Turkey have been traced to the more contagious variant first identified in Britain, according to the health ministry.
