"Extraordinary circumstances call for extraordinary actions, and while this testing and contact tracing effort is uNPRecedented, it is necessary and appropriate," said Austin Beutner, superintendent of Los Angeles Unified.
As new COVID-19 cases are reported at K-12 schools that have reopened, many others are facing the difficult decision of whether or not to return to in-person classes.
Medical experts warn it could take years before students and teachers can return to in-person education safely without masks, social distancing and other measures intended to curb the spread of the coronavirus.
A latest report released by the American Academy of Pediatrics and the Children's Hospital Association showed 75,755 new child cases reported from July 30 to Aug. 13, a 24 percent increase in child cases over two weeks.
"While children represented only 9.1 percent of all cases in states reporting cases by age, over 406,000 children have tested positive for COVID-19 since the onset of the pandemic," said the report.
Zhang Zuofeng, a professor of epidemiology and associate dean for research with the school of public health at University of California, Los Angeles, told Xinhua that the increase in infections among children may be related to such factors as more gatherings of younger ones and going back to school during the pandemic.
The U.S. Centers for Disease Control and Prevention (CDC) has been stressing the importance of returning to school, saying the best available evidence indicates that COVID-19 poses relatively low risks to school-aged children. Death rates among school-aged children are much lower than among adults.
