With about 18,400 confirmed coronavirus cases, Iran is currently the third most-affected country in the world outside mainland China and Italy.
All of the country's schools and universities closed down February 23, along with many movie theaters and cultural centers.
Neighboring countries like Turkey and Pakistan also closed their borders with Iran. Iraq has also imposed an entry ban on any incoming Iranians.
The country released 54,000 prisoners to prevent outbreaks in its prisons.
According to Reuters, 23 members of Iran's parliament — 8% — developed the coronavirus, as well. One member, Fatemeh Rahbar, a conservative lawmaker from Tehran, died.
About 1,300 people have died.
The Iranian government has been accused of covering up the scale of the coronavirus and censoring the media's reporting on the outbreak. It also threatened the death penalty to those who hoard necessary materials or equipment.
