Hospitalized COVID-19 patients in the United States spend more time in the hospital and are more likely to require intensive care than patients in China, a new study says. The findings suggest that the coronavirus pandemic may be putting greater strain on U.S. hospitals than previously assumed, according to researchers. "The hospital resources needed to meet the needs of severely ill patients are substantial," said lead author Joseph Lewnard, an assistant professor of epidemiology at the University of California, Berkeley.
