Southwestern US COVID Surge: What the Stratus Variant and Policy Shifts Mean for Fall
A concerning trend is emerging as we head into fall: COVID-19 positivity rates in the Southwestern United States have climbed to 12.5%, the highest in the nation. Coupled with record wastewater levels in Los Angeles County, this spike, driven by the highly contagious “Stratus” variant, raises critical questions about our preparedness for the upcoming respiratory virus season – especially given recent changes to CDC recommendations.
The Rise of Stratus and Evolving Immunity
The SARS-CoV-2 virus continues to demonstrate its remarkable ability to adapt. The Stratus variant, first identified in Asia earlier this year, rapidly became dominant in the U.S. by late June, now accounting for two-thirds of detected variants. This swift ascent underscores the virus’s capacity to evolve, evading immunity built through prior infections and vaccinations. While the national positivity rate currently sits at 9%, exceeding January’s post-holiday levels, it remains below last August’s peak of 18%. Importantly, current data indicates weekly deaths remain relatively low, though this is a lagging indicator.
A Controversial Policy Shift and its Fallout
Adding another layer of complexity, Health and Human Services Secretary Robert F. Kennedy Jr. recently oversaw the removal of the COVID-19 vaccine from the CDC’s recommended immunization schedule for healthy children and pregnant women. This decision, framed by Secretary Kennedy as a response to a lack of clinical data supporting repeat boosters in children, has ignited fierce debate. A coalition of leading medical organizations – including the American Academy of Pediatrics, the American College of Physicians, and the American Public Health Association – has filed a lawsuit, alleging the decision was “baseless and uninformed” and violated federal law by disregarding the recommendations of the Advisory Committee on Immunization Practices (ACIP).
The ACIP’s Stance on Boosters
The ACIP continues to advocate for updated COVID-19 vaccinations alongside annual flu shots. Their data demonstrates a significant benefit: the previous year’s booster reduced the risk of hospitalization by 44% and death by 23%. While acknowledging the diminishing effectiveness of boosters against newer strains, the panel maintains that the benefits outweigh the risks of rare adverse events like heart conditions and allergic reactions. However, uptake remains low. Only 23% of adults and 13% of children have received the 2024-25 booster, significantly less than the roughly 50% who received the updated flu shot.
Looking Ahead: What Can We Expect This Fall and Winter?
The convergence of the Stratus variant’s dominance, waning immunity, and reduced booster uptake paints a concerning picture for the fall and winter. We can anticipate increased COVID-19 transmission, potentially leading to a surge in cases, particularly in regions like the Southwest where rates are already high. The removal of the CDC recommendation for vaccinations, while politically motivated, is likely to further depress booster rates, leaving a larger portion of the population vulnerable.
Furthermore, the virus’s continued evolution means that existing boosters may offer limited protection against future variants. This necessitates ongoing surveillance and rapid development of updated vaccines. The current situation highlights the need for a more adaptable and proactive approach to COVID-19 management, moving beyond blanket recommendations to targeted strategies based on individual risk factors and local transmission rates.
The low uptake of boosters compared to the flu vaccine suggests a growing fatigue with COVID-19 precautions and a potential erosion of public trust in health recommendations. Addressing this requires transparent communication about the evolving risks and benefits of vaccination, as well as efforts to combat misinformation.
Preparing for the Respiratory Virus Season
Given the current trajectory, individuals should consider taking proactive steps to protect themselves and their communities. This includes staying up-to-date on vaccinations (both COVID-19 and flu), practicing good hygiene (handwashing, covering coughs), and considering masking in crowded indoor settings. Monitoring local wastewater surveillance data, like that provided by the CDC’s National Wastewater Surveillance System, can provide early warning signs of increasing transmission in your area.
