CDC Reports Rising Flu Activity Nationwide, ER Visits Surge

The CDC reported a significant rise in flu activity across the U.S., with the flu test positivity rate increasing to 25% as of January 18, up from 19% the previous week. Emergency department visits for flu have surged, particularly among infants, older children, and teens, accounting for 5.2% of overall ER visits. Although flu remains a pressing concern, COVID-19 and RSV show signs of stabilization and decline, with lower ED visits and hospitalization rates for COVID-19 compared to previous winter seasons. Experts stress the importance of vaccination and preventive measures for vulnerable populations as flu-related hospitalizations and deaths rise, notably among older adults. Overall, the latest data underscores the unpredictable nature of flu spread and the need for ongoing vigilance and resource planning in health facilities. The CDC has shifted its reporting format, limiting detailed flu information typically provided in its FluView updates.
