Key Health Trends of 2024 and Their Implications for 2025
In 2024, COVID-19 slipped into the background as an endemic virus alongside flu and RSV, with case and death rates dropping significantly. Fewer public health mandates and lower vaccine uptakes underscored its diminished visibility, even as early 2025 sees continued policy adjustments.

In 2024, COVID-19 largely receded from the headlines as case numbers dropped to historic lows, and the virus became one in a cluster of endemic respiratory illnesses such as seasonal flu and RSV. With vaccination rates falling—for example, California’s fall vaccine uptake dropped to just 12%—and COVID slipping to the 10th leading cause of death in the U.S., visible reminders of the pandemic became increasingly rare, with mask mandates confined mainly to hospitals during peak flu season.
Early 2025 has already seen significant policy and public health developments. Reuters reported on April 12 that WHO members are close to finalizing a treaty to bolster global defenses against future pandemics. Other sources note new legal and cybersecurity measures affecting HIPAA enforcement (Reuters, April 7) and evolving approaches to COVID-19 management, including a smaller winter wave in the U.S. that is pressuring firms like Pfizer to ramp up non-COVID treatments. Experts continue to advise that despite its endemic status, vaccines and new preventive strategies remain vital for protecting vulnerable populations.
