All people must observe the health protocols and social distancing at least for the next six months until a safe and effective vaccine is developed and widely distributed, Rouhani said on Sunday.
“We must know that we will have this situation for another six months or maybe longer,” he said.
The Iranian president added that the government has currently no plans to intensify restrictive measures as any decision in this regard may cause fear among people and affect their mental health.
“We should behave moderately and know that this virus will be with us for a while and we should be prepared,” Rouhani said.
Rouhani’s remarks came a day after the country’s Health Ministry said Iran is witnessing a decrease in the number of infections, hospitalizations and deaths by the coronavirus with the cooperation of the people over the past month.
However, concerns have grown over holding the Muharram mourning rituals in commemoration of Imam Hussein (PBUH), the third Imam of Shias, in the coming weeks.
The country’s National Headquarters for Managing and Fighting the Coronavirus on Sunday announced the instructions for holding the events, such as observing social distancing, wearing a mask and reducing the hours of the ceremonies to prevent the further spread of the coronavirus.
Iran’s Health Ministry spokeswoman Sima Sadat Lari said on Sunday that 163 more Iranians died from the coronavirus from Saturday to Sunday, bringing the total death toll to 18,427.
She added that 2,020 people tested positive for the coronavirus during the same period. Lari noted that a total of 326,712 Iranians have been confirmed infected with the COVID-19.
Some 4,022 other COVID-19 patients are in critical condition and being treated in intensive care units, the spokeswoman said.
She also put the number of those who have so far recovered from the viral infection at 284,371.
The spokeswoman added that more than 2,686,000 coronavirus diagnostic tests have been carried out in Iran so far.
Iran, the worst-hit country from the coronavirus in West Asia, has been battling a resurgence of the virus, with official figures showing a rise in both new infections and deaths since a two-month low in May.
This prompted authorities to make wearing masks mandatory in enclosed spaces and reimpose restrictions lifted gradually since April to reopen the country’s sanctions-hit economy.
