Iran on Wednesday announced registering 2,011 new COVID-19 infections, raising the overall number in the country to 177,938.
Health ministry spokeswoman Sima Sadat Lari who announced the new number said fatalities had also reached 8,506 with 81 new deaths over the same period.
The new infections come in line with a recent surge in cases that President Hassan Rouhani attributed to increased testing.
"When more tests are done, then naturally more cases are identified," Rouhani told a televised meeting of his cabinet.
But the high number of recent cases "does not have a negative aspect to it, and people should not worry", he added, AFP reported.
The Health Ministry says it has carried out more than one million COVID-19 tests since it reported the country's first cases on February 19.
There has been scepticism at home and abroad about Iran's official figures, with concerns the real toll could be much higher.
Rising infection figures since a low in early May and lax observance of social distancing have worried authorities, which have reiterated calls for strict adherence to health protocols.
