Iran on Thursday confirmed 221 additional fatalities from the novel coronavirus, bringing the nationwide death toll to 15,074, according to the Health Ministry.
A further 2,621 people tested positive for COVID-19 in the last 24 hours, raising the overall count to 284,034, ministry spokeswoman Sima Sadat Lari said.
Noting that more than 247,230 people had so far recovered from the disease, Sadat Lari added that 3,667 patients remained in critical condition.
Over 2.25 million tests have been conducted in the country to date, she said.
The alarming surge in daily fatalities has sent shockwaves across Iran as the healthcare system is already overwhelmed.
One of the first countries in the region to bear the brunt of the COVID-19 outbreak, the first two deaths in Iran were reported in the city of Qom, 140 kilometers (87 miles) south of Tehran, on Feb. 19.
In the first wave of the virus, single-day deaths peaked on April 4 with 158 fatalities, before dropping to their lowest, 34, on May 25.
After a remarkable comeback in June that prompted authorities to ease the lockdown, daily cases and deaths both saw a steep rise in July.
The government has made it mandatory to wear masks in public places in an effort to contain the new surge in infections.
Last week, Iran's Health Ministry said in a report that about 30 to 35 million people in the country were likely to be affected by the deadly virus in the coming months.
The report said that an estimated 25 million people in Iran had already contracted the disease in the past five months, including around 14,000 deaths.
