23 out of a total of 290 Iranian MPs have been infected with the new coronavirus, citing a statement by parliament speaker Abdul Reza Misri, CNN said.
That's about 8% of all legislators. Misri announced the results of the tests on Tuesday, citing a letter addressed to Iran's top leader Ayatollah Ali Hamene.
Members are advised to stop contacting people to prevent further spread of Covid-19 disease.
Iranian media reported on Monday that senior leader Advisor Mohamad Mirmohamadi has died of a new coronavirus disease at the age of 71. Last Thursday, one of the country's leading priests, Hadi Koshrosaki, died of an illness.
Vice President Masumeh Ebtekar and Deputy Minister of Health Iraj Hariri also became ill with Covid-19.
The spread of coronavirus in Iran became known last week. By Monday, at least 66 people had died and 1,501 confirmed infections.
Iran has the highest number of coronavirus infections in the Middle East and the most dead of the epidemic outside China, where the virus began to spread last December.
Due to the spread of the virus, the Iranian parliament has shut down and schools and universities have been closed. All mass events, including Friday prayers, have been abolished in the country.
