Respiratory virus activity in the United States is still elevated but continues to decline, with only 6 jurisdiction reporting high levels, down from 10 the previous week, the Centers for Disease Control and Prevention (CDC) said today in its data updates.
The study was based on ED visits to nine US hospitals participating in the Pediatric Emergency Care Applied Research Network Registry from 2017 to 2022.
Experts worry a recent rise in long COVID cases — fueled by a spike in winter holiday infections and a decline in masking and other measures — could continue into this year.
