Iran has been struggling to contain the virus since announcing its first cases in February -- two deaths in the Shiite holy city of Qom.
Official figures have shown an upward trajectory in new confirmed cases since early May, when Iran hit a near two-month low in daily recorded infections.
Iran closed schools, cancelled public events and banned movement between its 31 provinces in March, but progressively lifted restrictions from April to try to reopen its sanctions-hit economy.
Tehran,
Iran reported on Monday more than 200 new coronavirus fatalities that took the overall toll in the Middle East's deadliest outbreak beyond 13,000.
