COVID-19 Cases Rise Nationwide as New Variants Emerge
Table of Contents
Washington, D.C. – A summer surge of COVID-19 is underway across the United States, wiht cases increasing in over half of the states. Health officials are tracking new variants and adjusting vaccine recommendations as the virus continues to evolve. This resurgence underscores the ongoing need for vigilance and informed public health practices.
Current COVID-19 Activity in the U.S.
As of the week ending August 9, 2025, approximately 8.9% of the 28,051 Americans tested for COVID-19 were positive, marking a 0.6% increase from the previous week. Hospitalization rates also saw a slight uptick, with 0.4% of cases resulting in death and 1% requiring emergency room visits-increases of 0.1% each.
The Centers for Disease Control and Prevention (CDC) is monitoring thes trends, though reduced reporting from states has prompted a shift towards longer data timeframes for variant tracking. The CDC’s COVID Data Tracker provides weekly updates on cases, hospitalizations, and deaths.
Regional Hotspots
Several regions are experiencing higher positivity rates then others. States in the western and Southern parts of the country-including Washington, Oregon, Idaho, California, Nevada, Arizona, New Mexico, Texas, Oklahoma, Arkansas, Louisiana, and Alaska-are reporting elevated levels of COVID-19 transmission.
Dominant COVID-19 Variants
Recent data indicates that variant NB.1.8.1 remains the most prevalent strain, accounting for 43% of cases as of the two weeks ending in June.LP.8.1 follows at 31%, while XFG represents 14% of reported cases. The CDC’s variant tracking data shows a significant rise of NB.1.8.1, from 0% in April to 43% by the end of June.
Did You Know? The rapid evolution of COVID-19 variants highlights the virus’s ability to adapt and evade immunity, necessitating ongoing surveillance and vaccine updates.
The variant XFG, a recombination of F.7 and LP.8.1.2, is also gaining traction, increasing from 0% of cases through March to 11% in early June and 14% by late June.
| Variant | Percentage of Cases (June End) |
|---|---|
| NB.1.8.1 | 43% |
| LP.8.1 | 31% |
| XFG | 14% |
Updated COVID-19 Vaccine Guidance
In May 2025, Health and Human Services Secretary robert F.Kennedy Jr. announced changes to the CDC’s recommended immunization schedule. The COVID-19 vaccine is no longer universally recommended for healthy children and pregnant women, a decision that deviated from previous expert guidance and bypassed standard scientific review processes.This decision sparked debate among public health officials.
Currently, the CDC recommends COVID-19 vaccination for individuals 65 years and older, and those with underlying health conditions. This shift could perhaps limit access to the vaccine for other groups, including healthcare workers and individuals with vulnerable family members.
Pro Tip: Staying up-to-date with your COVID-19 vaccinations remains a crucial step in protecting yourself and others, especially as new variants emerge.
Despite these changes, the World Health Organization (WHO) continues to recommend vaccination for high-risk groups, emphasizing that currently approved vaccines are expected to remain effective against new variants. The WHO’s guidance aligns with recommendations from organizations like the american Medical Association (AMA) and the American academy of Pediatrics (AAP).
Recognizing COVID-19 Symptoms
While some reports suggest certain symptoms,like a severe sore throat,may be more common with specific variants,health agencies emphasize that there is no definitive evidence linking particular symptoms to specific strains. Common symptoms of COVID-19 include:
- Fever or chills
- Cough
- Shortness of breath or difficulty breathing
- Sore throat
- Congestion or a runny nose
- New loss of taste or smell
- Fatigue
- Muscle or body aches
- Headache
- Nausea or vomiting
Individuals experiencing trouble breathing, persistent chest pain, new confusion, inability to wake, or skin discoloration should seek immediate medical attention.
What steps are you taking to protect yourself and your loved ones from the current COVID-19 surge? How has the changing guidance impacted your decisions about vaccination?
The COVID-19 pandemic has fundamentally altered public health practices worldwide. The emergence of new variants,the development of vaccines,and the ongoing debate over public health measures demonstrate the complex and evolving nature of infectious disease control. Continued research, surveillance, and international collaboration are essential to mitigating the impact of future outbreaks.
