Flu Surge Hits 32 States as Holidays Near

A sharp rise in influenza cases is sweeping the United States during the busy holiday travel season. New data from the Centers for Disease Control and Prevention (CDC) shows 32 states and territories are now reporting "high" or "very high" levels of flu activity. The CDC tracks flu spread through outpatient visits. The term "jurisdictions" includes states, major cities, and territories. Health officials warn that holiday gatherings and travel can increase virus transmission. They urge people to get a flu vaccine, which is still the best protection. Other recommended steps include washing hands frequently, covering coughs, and staying home when sick. These actions can help slow the spread during a critical period.
