At present, there is scant data on the effects of the novel coronavirus COVID-19 in children, and children's role in virus transmission.

They said rulings on school reopenings should be left to local leaders because of variation in virus spread from community to community.
A day earlier, two of America's largest school districts -- Los Angeles and San Diego counties in California -- announced plans to hold classes online in the fall.
