Hospitalizations soar in US as flu-like illnesses now at highest rate on record: CDC

Historic flu surge hits US: Hospitalizations at record levels, flu-like illnesses surge to all-time high

NEW YORK: The United States is in the grip of an unprecedented flu season, with hospitalizations soaring and flu-like illnesses now at the highest rate on record, according to newly released data from the Centers for Disease Control and Prevention (CDC). The percentage of outpatient visits for respiratory illnesses has reached 8%, a figure not seen since 1997, with flu-like illness accounting for an overwhelming portion of these visits, primarily among children and young adults.

Flu activity hits record levels

For the week ending December 27, the CDC reported 32 states experiencing ‘very high’ flu activity, with hospitalizations up by 48.1% from the prior week. With over 120,000 hospitalizations this season and 11 million flu-related illnesses, the situation is critical. Tragically, at least nine pediatric deaths have already been recorded this season, underscoring the severity of this outbreak.

In New York, the crisis is particularly severe, with 72,133 flu cases reported in a single week, a record number for the state. Dr. James McDonald, the health commissioner for New York State, described the current flu season as “quite severe,” noting that flu cases, especially those linked to the H3N2 subclade K strain, continue to rise rapidly.

New flu strain dominates

The H3N2 subclade K strain, which has been circulating since the summer in countries like Canada, Japan, and the UK, is the primary driver of this surge. The strain has taken a heavy toll across the globe, and the CDC reports that nearly 90% of flu cases in the US this season are caused by influenza A, with a predominant focus on H3N2. This strain is especially dangerous because it is new to people’s immune systems, leaving large populations highly vulnerable to severe illness.

Unprecedented flu-like illnesses

In addition to the surge in flu hospitalizations, the CDC data also reveals an alarming spike in flu-like illnesses — a category that includes fever, cough, and/or sore throat. About 8% of visits to healthcare providers across the country have been for flu-like symptoms, surpassing any levels seen since the 1990s. Children and young adults are the most affected, with about 35% of outpatient visits for respiratory illnesses involving people under 24 years old. Children under age 5 account for 20% of these visits, underscoring the vulnerability of young populations to this aggressive strain.

Worsening situation: A multi-viral outbreak

Experts warn that flu-like illnesses are likely to continue climbing in the coming weeks. The ongoing circulation of not only influenza but also COVID-19 and respiratory syncytial virus (RSV) is putting additional strain on hospitals. The CDC recommends that everyone aged 6 months and older get an annual flu vaccine to reduce the risk of illness, hospitalization, and death.

Despite the availability of the flu vaccine, only 42% of adults and 42.3% of children had received their flu shot as of mid-December, a figure that remains stagnant compared to previous years. This low vaccination rate is concerning, particularly in light of the 289 pediatric flu deaths recorded last season, most of which involved unvaccinated children.

Preventive measures: Get vaccinated

The CDC continues to urge individuals to get their annual flu shots, which can prevent millions of flu-related illnesses, doctor visits, and hospitalizations each year. For those at higher risk of complications, including the elderly and children, the flu vaccine is critical. In addition to vaccination, practicing good hand hygiene, avoiding sick individuals, and staying home when ill are important steps to curb the spread of the flu.

Record flu-related deaths: A stark reminder

Pediatric flu-related deaths have been on the rise, with the latest being 16-year-old Ryleigh Spurlock from Ohio, whose condition deteriorated rapidly from ordinary flu symptoms to septic shock and pneumonia within 24 hours. Experts are particularly concerned about pediatric deaths, as the flu season continues to unfold, with influenza A causing a significant burden on young populations.

Looking ahead: Flu season not over yet

As we approach the peak of this flu season, health officials are preparing for even more challenging weeks ahead. Experts predict that the number of cases will continue to climb as we move deeper into winter, with no immediate end in sight. Hospitals across the country remain under heavy pressure, and the H3N2 subclade K strain continues to spread rapidly.
