The country has seen more than 62,000 confirmed cases of Covid-19, with more than 4,000 deaths.
And in a desperate bid to fight the virus, a worrying number of people have drunk high-concentration alcohol with the false belief it will protect them.
It has led to thousands being poisoned.
We previously reported how dozens had died from the false rumour - but a significant number of others have now suffered the same fate.
Iranian judicial spokesman Gholam Hossein Esmaili said: "The numbers are very high and are beyond our expectations.
"Alcohol consumption is not a cure but can be lethal."
Speaking to state-run Tasnim News Agency, he added: "A number of people have been arrested... and we will deal with them decisively.
"They must be held accountable for their criminal acts, for causing death and damage to citizens."
