According to the public relations of Akbar Children's Hospital, Dr. Mohammad Hassan Aalami, a pediatric infectious disease specialist and associate professor at Mashhad University of Medical Sciences, said: "A mutated version of the corona virus called Omicron is more contagious than the delta trend and more genetic mutations have been reported." The World Health Organization reports that previous infections with the corona virus have had less protection against Omicrons than other species. Anyone with Omicron can pass it on to others, even if they have been vaccinated or are non-symptomatic

The frist information indicate that Omicron was less severe than delta in children, but the World Health Organization warned against considering Omicron as a mild disease agent. The rate of hospitalization of children with the corona virus in the United States is about one in one hundred thousand children, which is lower than the rate of hospitalization during the flu season, which is three to five hospitalizations per one hundred thousand children
