Nine out of 10 cases of the virus in the Middle East come from the Islamic Republic. Fears remain that Iran may be underreporting its cases. Days of denials gave the virus time to spread as the country marked the 41st anniversary of its 1979 Islamic Revolution with mass demonstrations. For most people, the new coronavirus causes only mild or moderate symptoms. For some it can cause more severe illness. (AP Photo/Mohammad Ghadamali, File)
