As winter continues, respiratory illnesses remain a significant public health concern globally. Recent data indicates a shifting landscape in the prevalence of COVID-19, influenza, and respiratory syncytial virus (RSV). While influenza cases are declining, RSV is experiencing a slight uptick, and COVID-19 continues to circulate, with new variants emerging. Understanding the current trends and taking preventative measures is crucial for protecting individual and community health. This report provides an overview of the latest data and guidance on mitigating the spread of these respiratory infections.
Monitoring respiratory virus activity is essential for public health officials to assess risk and implement appropriate interventions. The Centers for Disease Control and Prevention (CDC) tracks these illnesses through various methods, including emergency department visits and wastewater surveillance. Wastewater analysis, in particular, offers an early warning system, detecting viral traces even in asymptomatic individuals. The CDC’s latest data highlights the dynamic nature of these viruses and the importance of ongoing monitoring.
Flu Trends: A Continuing Decline
The latest reports show a positive trend in influenza cases. According to data from February 9th to 15th, 2026, laboratory-confirmed influenza cases decreased by 42%, falling from 555 to 321. This marks the fifth consecutive week of decline, indicating a diminishing circulation of the virus. This decrease is a welcome sign as we move further into the winter season. The majority of identified influenza cases, 98.7%, are influenza A, including avian influenza A (H5), while 1.3% are influenza B. The CDC provides detailed information on influenza strains and their prevalence.
RSV: A Slight Increase, Primarily Affecting Young Children
While influenza cases are decreasing, respiratory syncytial virus (RSV) is showing a slight increase. A 3% rise in confirmed cases was observed, with 92 cases reported compared to 89 the previous week. This increase, though modest, warrants attention, particularly as RSV disproportionately affects young children. Since October 2025, 55% of RSV infections have been diagnosed in children under ten years of age, suggesting that the virus continues to pose a greater risk to this age group. Understanding the risks of RSV is crucial for parents and caregivers.
COVID-19: Decreasing Cases and Evolving Variants
COVID-19 cases are also showing a downward trend. From February 9th to 15th, 2026, positive SARS-CoV-2 cases decreased by 10%, dropping from 73 to 66. Viral concentration detected in wastewater is also slightly decreasing, suggesting a reduction in community transmission. But, the virus continues to evolve, with several variants currently circulating. The predominant variants are XFG (45.5%), its subvariant XFG.3 (26.7%), and NB.1.8.1 (18.2%). Staying informed about COVID-19 variants is important for understanding potential changes in transmissibility and severity.
Distinguishing Between COVID-19, RSV, and Influenza
Differentiating between COVID-19, RSV, and influenza can be challenging, as they share many overlapping symptoms. Common symptoms include fever, cough, sore throat, fatigue, and congestion. However, there are some key distinctions. COVID-19 is uniquely associated with loss of taste or smell, although this symptom is less common with newer variants. RSV often presents with wheezing and difficulty breathing, particularly in infants and young children. Influenza typically causes more abrupt onset of symptoms, including body aches and high fever. Older adults and individuals with underlying health conditions are at higher risk of severe illness from all three viruses.
As one nurse shared with RWJBarnabas Health, COVID-19 can manifest very differently in individuals. She experienced severe weakness, vomiting, diarrhea, and a persistent fever, ultimately requiring hospitalization and oxygen support. This highlights the unpredictable nature of the virus and the importance of seeking medical attention if symptoms worsen.
Protecting Yourself and Others: Essential Preventative Measures
Preventing the spread of respiratory viruses requires a multi-faceted approach. Practicing good hygiene is paramount. This includes washing hands frequently with soap and water for at least 30 seconds, covering coughs and sneezes with a tissue or elbow, and avoiding touching the face. Disposing of used tissues properly and immediately washing hands afterward is also crucial.
Minimizing close contact with others, especially those who are sick, can significantly reduce transmission. Avoiding crowded spaces and staying home when feeling unwell are essential steps. Regular ventilation of indoor spaces, opening windows for at least 10 minutes several times a day, helps to dilute airborne viruses. Vaccination remains a critical tool in protecting against influenza and COVID-19. The CDC recommends that everyone six months and older receive an annual influenza vaccine and stay up-to-date with COVID-19 vaccinations and boosters.
Key Takeaways
- Influenza cases are currently declining, marking a fifth consecutive week of reduction.
- RSV cases are experiencing a slight increase, primarily affecting young children.
- COVID-19 cases are decreasing, but new variants, including XFG, XFG.3, and NB.1.8.1, are circulating.
- Practicing good hygiene, minimizing close contact, and staying up-to-date with vaccinations are essential preventative measures.
The ongoing circulation of respiratory viruses underscores the importance of continued vigilance and preventative measures. While the current trends are encouraging, the situation remains dynamic. Public health officials will continue to monitor these viruses closely and provide updated guidance as needed. The next update from the CDC on respiratory virus activity is scheduled for February 27th, 2026.
