Tehran (IP) -Deputy of Iran's Health Minister said observing health protocols and using mask has reduced the number of patients in hospitals by a quarter and the death toll rate by a third.

Iran Press/Iran News: At a conference meeting, Alireza Raeesi stated that 400 cities are in the yellow zone and 43 cities are in the orange zone. He noted that 18 orange cities are for Mazandaran Province.

"We learned from coronavirus that gatherings should not increase as disease and death toll decrease," he pointed.

Alireza Raeesi expressed concern that in cold weather and indoor family gatherings, the disease would increase again.

He also noted that experience has shown that whenever cities turn yellow, the disease increases again because of ignoring health protocols.
