Respiratory illnesses, including influenza, COVID-19, and respiratory syncytial virus (RSV), are all showing a decline in reported cases, according to the latest data released by health officials. This downward trend, particularly noticeable during the week of February 23rd, builds on a similar pattern observed the previous week for influenza and COVID-19. Understanding the current state of respiratory infections is crucial for public health planning and individual preventative measures.
The weekly health report revealed a decrease in laboratory-confirmed influenza cases, falling from 183 to 145 during week 9 (February 23rd to March 1st). This represents a 21% reduction compared to the prior week. Health officials note that 94.3% of identified influenza cases are influenza A, even as 5.7% are influenza B. This marks the seventh consecutive week of decline in influenza circulation.
Similarly, a 29% decrease in RSV cases was observed, with 41 confirmed cases reported compared to 58 the previous week. Since October 2025, 54% of RSV infections have been detected in children under ten years of age, suggesting that the virus continues to disproportionately affect younger populations. RSV can cause mild, cold-like symptoms, but can similarly lead to more severe illness, such as bronchiolitis and pneumonia, particularly in infants and young children.
COVID-19 Cases Continue to Fall
Positive SARS-CoV-2 cases are also decreasing, moving from 56 to 33 cases of COVID-19, a 41% reduction week-over-week. Importantly, the viral concentration detected in wastewater has also decreased, providing an additional indicator of declining community transmission. Monitoring wastewater provides an early warning system for changes in COVID-19 levels within a population.
Recent genomic sequencing data indicates that the XFG variant (36.5%), the BA.3.2 variant (25.2%), and the NB.1.8.1 variant (24.5%) are currently the most prevalent strains of the virus. These variants are being closely monitored by public health agencies to assess their transmissibility and potential impact on vaccine effectiveness.
Understanding the Differences Between Respiratory Viruses
While symptoms can overlap, it’s important to remember that influenza, COVID-19, and RSV are caused by different viruses. The Centers for Disease Control and Prevention (CDC) highlights that COVID-19 has, historically, spread more easily than the flu. Symptoms alone are often insufficient to distinguish between these illnesses, and testing is necessary for accurate diagnosis.
Early and accurate diagnosis is key, as treatment options are available for both COVID-19 and influenza. Getting treated promptly can reduce the risk of severe illness. Testing can also identify instances of co-infection – having both flu and COVID-19 simultaneously – although this is uncommon. Individuals with both infections may experience more severe symptoms than those with either virus alone.
The Impact on Younger Children
The disproportionate impact of RSV on children under ten years ancient underscores the importance of preventative measures within this age group. Parents and caregivers should be vigilant about recognizing symptoms of RSV and seeking medical attention when necessary. While most RSV infections are mild, some children may require hospitalization.
Looking Ahead
Health officials will continue to monitor trends in respiratory illnesses closely. The next report, covering the week of March 2nd to March 8th, will provide further insight into the ongoing decline and the continued circulation of these viruses. Individuals are encouraged to stay informed about the latest recommendations from public health authorities and to practice fine hygiene, including frequent handwashing and covering coughs and sneezes.
