The CDC has released a new report showing how quickly COVID-19 can spread from child to child in a day care center, and it says up to 40% of children did not show any symptoms.

The agency says 12 children from three Utah child care facilities, including an 8-month-old, got COVID-19 and spread it to at least 12 people. It says the data shows children can carry the virus from child day care centers to their homes.

The CDC report suggests that children can get COVID-19 and spread it, but don't appear to experience severe illness from the virus compared to adults.

Dr. James Schneider, the chief of pediatric critical care at Cohen's Children’s Medical Center, says day cares need to set up an environment that is socially distant, require children 2 years old and older to wear masks and wash their hands often.

He says despite this, the regulations pose a challenge for young children who are naturally curious.

According to the American Academy of Pediatrics, 500,000 U.S. children have been diagnosed with COVID-19 between Aug. 20 and Sept. 3.

In Utah, the agency says it found at least two children in day care who had no symptoms and passed it onto other people, including a mother who was hospitalized.

Schneider warns that we are still are in the middle of pandemic, and even though a lot of progress has been made in New York, the colder weather months are coming and he encourages people to continue to follow the CDC guidelines.
