After a tough flu season, today’s respiratory virus update from the Centers for Disease Control and Prevention (CDC) offers a bit of good news: Doctors are seeing fewer people with influenza.

Cases of flu are declining in most of the country. While influenza A is on its way out, rates of influenza B—which tends to peak later in flu season—vary by region. Levels of influenza A in wastewater are low. Influenza B is not monitored in wastewater.

Most flu viruses reported this week were influenza A(H3N2) and influenza B. Nearly 93% of influenza A(H3N2) viruses since late September belong to subclade K, a new strain that was not included in this year’s flu shots.

About 5,640 people were admitted to the hospital for flu in the past week, nearly 2,000 fewer than the previous week, according to the CDC’s FluView report. Eight additional flu deaths were reported in children, bringing the total number for this season to 123. Among children who were eligible for a flu shot and whose vaccination status is known, 85% of children who died from flu were not fully vaccinated.

The CDC estimates that there have been at least 29 million illnesses, 360,000 hospitalizations, and 23,000 deaths from flu so far this season.

Although respiratory syncytial virus (RSV) levels remain high, the country seems to have gotten past the worst of RSV season, which has peaked in many regions of the nation. Levels of RSV in wastewater are low.

The number of COVID-19 infections is low, with low levels in wastewater. Although COVID-related emergency room visits remain low across the country, they are likely increasing in Florida and Massachusetts. According to the CDC, 2.3% of tests for COVID-19 were positive, along with 7.5% for RSV and 11.5% for the flu.
