Infections have soared in recent months, and on Friday, Iran again set a record for new virus cases in a single day with 14,051 cases, bringing the total to 922,397.
Iran has also recorded more than 400 daily virus deaths since last Saturday, the same day new tightened restrictions went into effect. Health Ministry spokeswoman Sima Sadat Lari said the death toll on Friday reached 47,095, after 406 people died since Thursday.
Since Saturday, some government offices and organizations had closed or began working with less than 30% of their employees, while banks, post offices, communications and other utilities worked with half their staff.
Those new lockdown measures also included shuttering most businesses, shops, malls, and restaurants, and are set to last two weeks.
Iran's government had recently resisted shutting down the country in an attempt to salvage an economy cratered by unprecedented American sanctions, which effectively bar Iran from selling its oil internationally. The Trump administration reimposed sanctions in 2018 after withdrawing from Tehran’s nuclear deal with world powers.
Earlier this month, authorities ordered a month-long nightly curfew for businesses in Tehran and 30 other major cities and towns, asking nonessential shops to keep their workers home. Still, enforcement in the sprawling metropolis remains a challenge.
