US COVID-19 Activity Rises: CDC Data Shows West Coast Surge & Vaccine Policy Shifts
Updated August 12, 2025 – A concerning trend is emerging across the United States as COVID-19 activity begins to heat up, according to the latest data from the Centers for Disease Control and Prevention (CDC). While overall infection rates remain relatively low, a noticeable increase in emergency department visits and a surge in viral activity, particularly on the West Coast, are prompting health officials to closely monitor the situation. This breaking news comes alongside significant adjustments to US COVID-19 vaccine policy, raising questions about the nation’s preparedness for potential future waves.
West Coast Leads the Rise in COVID-19 Cases
The CDC’s most recent sewage monitoring results, released last Friday, indicate a shift in viral activity from “low” to “medium” nationwide. However, the West Coast is experiencing the most pronounced increase. Hawaii and Louisiana are currently at an “extremely high” level of viral presence, while California, Alaska, Nevada, Utah, Colorado, Texas, Mississippi, Alabama, Indiana, South Carolina, and Florida are all categorized as “high.” This regional concentration suggests localized outbreaks are driving the national uptick. It’s a stark reminder that even as we move further from the height of the pandemic, COVID-19 remains a dynamic threat.

Beyond COVID-19: Respiratory Illness Landscape
While COVID-19 is showing signs of resurgence, the CDC reports that the overall incidence of respiratory diseases remains “very low.” Influenza is currently at a “low” level, and respiratory syncytial virus (RSV) is also categorized as “very low.” This provides a degree of reassurance, but experts caution that the situation can change rapidly, especially as we approach the fall and winter respiratory virus season. Understanding the interplay between these viruses is crucial for effective public health strategies.
Significant Changes to US COVID-19 Vaccine Policy
Adding another layer to the evolving situation, US Secretary of Health and Human Services Robert Kennedy Jr. has recently implemented changes to the COVID-19 vaccine policy. These adjustments include a reshuffling of CDC vaccine consultants, a requirement for influenza vaccines to be free of mercury ingredients, and the cancellation of official recommendations for COVID-19 vaccination for pregnant women and healthy children. These policy shifts are already sparking debate among medical professionals and public health advocates, with concerns raised about potential impacts on vaccination rates and overall population immunity. The long-term consequences of these changes remain to be seen.
New Variant NB.1.8.1: A Global Concern
The situation is further complicated by the emergence of a new COVID-19 variant, NB.1.8.1, which has been circulating in China since the beginning of the year. Reports indicate that this variant is highly contagious, leading to a dramatic increase in infections and deaths across all age groups in China. However, due to limited transparency and concerns about data accuracy, the true scale of the outbreak remains difficult to assess. This highlights the importance of international collaboration and data sharing in tracking and responding to emerging variants. The CDC has not updated its estimated data on variant prevalence since mid-June, adding to the uncertainty.
The story of NB.1.8.1 serves as a potent reminder of the virus’s ability to mutate and evade immunity. It underscores the need for continued vigilance, robust surveillance systems, and adaptable public health measures. Staying informed about the latest developments and following the guidance of health officials is more important than ever.
