Projected numbers of children aged 0 to 17 years in the United States who will require hospitalization for COVID-19 during 2020.

A new study suggests that COVID-19 is possibly striking more children than expected, an estimate that could vastly underestimate the demand for health care systems.

Iran PressAmerica: The number of children infected with the coronavirus is far more extensive than what is currently reported -- a hidden detail that could vastly underestimate the demand for health care systems and pediatric intensive care units (PICUs).

A new study published in the "Journal of Public Health Management and Practice" from the University of South Florida (USF) and the Women's Institute for Independent Social Enquiry (WiiSE), estimates that for each child who requires intensive care for COVID-19, there are 2,381 children infected with the virus. This calculation follows a report from the Chinese Center for Disease Control and Prevention regarding its clinical study of over 2,100 children in China with COVID-19, Eurekalert reported.

According to the North American registry, Virtual PICU Systems, 74 children in the US were admitted to PICUs between March 18 and April 6, signaling an additional 176,190 children were likely infected during this timeframe. Researchers say that if as many as 25 percents of the US population becomes infected with the coronavirus before the end of 2020, 50,000 children with severe illness will need to be hospitalized, with 5,400 of them critically ill and requiring mechanical ventilation. 

Clinical reports indicate the average length of stay for pediatric COVID-19 is 14 days. According to a national survey aimed to evaluate the US pediatric critical care capacity and published in "Critical Care Medicine," there are approximately 5,100 PICU beds in the US.

"Although the risk of severe illness from COVID-19 is lower in pediatric cases than adults, hospitals should be prepared and have the proper equipment and staffing levels to deal with a potential influx of younger patients," said author Jason Salemi, associate professor of epidemiology in the USF College of Public Health.

Researchers point out the infection rate will be much higher for children in low-income families with parents in blue-collar and service jobs, which precludes the option of working from home. There's also an increased risk to children who live in urban public housing projects due to the close proximity of housing units and small communal recreation and commons areas.

The study's authors recommend all state health departments and the CDC begin reporting confirmed COVID-19 cases in age-specific tables, using the standard 5-year age groups for health surveillance and make the data publicly available.

The US has the most COVID-19 cases of any country with more than 690,000 and the most fatalities with at least 35,000, according to data aggregated by Johns Hopkins University. 

The global case tally for the coronavirus that causes COVID-19 has climbed to 2.2 million. The death toll rose to more than 150,000.
