NEW DELHI: So far, data suggest that children under the age of 18 years represent about 8.5% of reported cases, with relatively few deaths compared to other age groups and usually mild disease.
However, cases of critical illness have been reported. As with adults, pre-existing medical conditions have been suggested as a risk factor for severe disease and intensive care admission in children.
Further studies are underway to assess the risk of infection in children and to better understand transmission in this age group.
