This episode discusses four MMWR reports. First, extreme heat caused more emergency department visits in several U.S. regions in 2023 than in previous years. Second, health-related social needs, such as social isolation, dissatisfaction with life, and barriers to health care access, were associated with decreased mammogram use. Third, nursing home residents continued to get COVID-19 infection and be hospitalized during the most recent respiratory virus season. Fewer than half of nursing home residents were up to date with COVID-19 vaccines by February 2024. Finally, original COVID-19 vaccines protected children against hospitalizations, but the protection decreased over time.
