Why cases are rising across the US

Key Points:
- COVID-19 cases are rising across the U.S. in a predictable "summer surge," with increases noted particularly in the South and West, according to CDC data and wastewater testing trends.
- The virus has settled into a pattern of biannual waves, peaking in summer and winter, driven by environmental factors like indoor gatherings during hot weather and behavioral changes such as school reopening.
- New variants and waning immunity contribute to breakthrough infections, with immunity from prior infections lasting roughly six months, leading to less severe but recurring cases.
- Despite the rise in cases, severe illness and emergency visits remain low, though vulnerable populations such as older adults, infants, and immunocompromised individuals still face higher risks.
- Experts recommend regular immunizations, testing when symptomatic, improving ventilation, practicing good hygiene, and proportionate vigilance rather than alarm to manage the ongoing COVID-19 waves.
