Summer COVID Surge: What You Need to Know

Health tracking data reveals a notable increase in COVID-19 activity across the United States, with wastewater testing indicating a rise in several states, primarily in the South and along the West Coast. While overall national rates remain low, this summer's trend follows a predictable pattern of seasonal ebbs and flows.

Factors contributing to this rise include a decrease in COVID-19 vaccination rates; as of the current period, only 17.5% of American adults and 8.9% of children have received the 2025-2026 vaccine. Increased summer travel, leading to crowded conditions in transportation and at destinations, also plays a significant role in virus transmission.

Public health experts advise continued vigilance, emphasizing effective protective measures. Hand washing, masking in crowded or indoor public settings, and staying home when sick are recommended. Individuals experiencing respiratory symptoms are encouraged to test for COVID-19, as current at-home tests can detect circulating variants. Those in high-risk groups who test positive may be eligible for antiviral treatments like Paxlovid.

Vaccination remains the most effective defense against severe illness, hospitalization, and death. While the 2025-2026 vaccine is available, experts suggest waiting for the updated 2026-2027 formulation expected in the fall for potentially better protection against current strains. However, high-risk individuals or those with upcoming travel may consider getting the existing vaccine. As flu season approaches, experts also stress the importance of timely vaccinations for influenza and other preventable diseases like measles.
