The number of people in Iowa hospitalized because of the novel coronavirus retreated Sunday from its record high, but remained at its second-worst level ever.The soaring number of hospitalizations — Iowa set records three times last week for new highs — are fueling concerns that hospitals in the state will be hard-pressed by the end of the year to have the capacity to handle patients who suffer some of the diseases’s worst symptoms.Unless more steps are taken to mitigate the spread of the disease, Iowa will run out of intensive-care unit beds for COVID-19 patients in early December and remain short until early January, according to projections from the respected Institute for Health Metrics and Evaluation at the University of Washington.State public health data shows that Saturday’s record 545 COVID-19 hospitalizations inched down to 541 in the 24-period that ended at 11 a.m.
