A New Flu Strain is Causing a Surge in US Cases - But is the Worst Over?
It's a stark reality: at least 18 million Americans have already been hit by the flu this season. The Centers for Disease Control and Prevention (CDC) reports a significant impact, with 230,000 hospitalizations and a tragic 9,300 deaths attributed to the virus. But is this the beginning of the end, or are we in for a longer, more challenging season? Let's dive in.
Flu activity appears to be easing slightly after weeks of intense spread, but health officials caution that the season is far from over. Fourteen states are reporting "very high" levels of flu-like illness, while 19 states are seeing "high" activity, according to ABC News. In the week ending January 10th, at least 15 flu-associated deaths were recorded among children, bringing the total pediatric toll to 32. Last season saw a record 289 children die from the flu, the highest since the CDC began tracking in 2004, making this season’s child fatalities a significant concern. And this is the part most people miss... Among children whose vaccination status is known, 90% of deaths occurred in those not fully vaccinated against influenza.
Recent government data indicates that several measures of flu activity have declined for two consecutive weeks. There has been a notable drop in hospitalizations and a smaller but significant decrease in visits to medical offices for flu-like illness. The number of states reporting high flu activity has fallen from 44 to 36. While COVID-19 and respiratory syncytial virus (RSV) haven't seen large surges during the same period, the CDC describes the overall respiratory virus season as "moderate."
But here's where it gets controversial... Experts warn that a decline in certain indicators doesn't necessarily signal the flu season has peaked. Dr. William Schaffner, an infectious diseases specialist at Vanderbilt University, points out that "We’ve had other seasons where we’ve had a peak, it’s gone down, but we’ve nonetheless had a prolonged season.”
This season is dominated by the influenza A H3N2 virus, a subtype historically associated with more severe illness, especially among older adults and young children. Genetic analysis shows that the vast majority of H3N2 viruses circulating are part of a variant known as subclade K, which differs from the strain targeted by this year’s vaccine. This mismatch may reduce vaccine effectiveness against infection, though vaccination still provides protection against severe disease. Flu is a highly contagious respiratory infection that spreads quickly during winter months. Symptoms often strike suddenly, ranging from fever, cough, and sore throat to body aches and extreme fatigue. In children, vomiting and diarrhea are more frequently seen. Not all infected people develop a fever, making early detection harder. Though many recover within days, flu can trigger serious complications including pneumonia and worsening of existing health conditions.
Health authorities warn that older adults above 65, pregnant women, young children under five — particularly those below two — and people with chronic diseases such as asthma, diabetes, and heart ailments remain the most vulnerable to severe illness. Doctors continue to urge all Americans aged six months and older to get vaccinated. "We’re still in the thick of flu season, so it’s not too late to get your flu shot," said Dr. Aaron Milstone, pediatric director of infection prevention at Johns Hopkins Health System. "The goal of the flu vaccine is really to keep people out of the hospital and to keep them alive… it’s not 100% effective at preventing infection, but hopefully it prevents complications that can lead to hospitalization or death."
