Flu activity in the United States remains elevated, with older adults experiencing the highest hospitalization rates, according to a recent report from the Centers for Disease Control and Prevention (CDC). This trend underscores the vulnerability of this population to influenza and the importance of preventative measures within nursing home settings.
The CDC’s weekly update, released on February 7th, reveals that flu-related hospitalization rates are on the rise across all age groups. The current rate, tied with the 2017-2018 season, represents the highest weekly peak since the 2010-2011 season. However, the most concerning statistic is the disproportionate impact on older adults, who, along with adults aged 50-64, are experiencing the highest hospitalization rates. “These high hospitalization rates in older adults are a significant concern and highlight the need for increased vigilance and preventative measures in nursing homes,” says an unnamed industry expert.
The CDC data paints a concerning picture of the current flu season. Positive flu test results stand at 31.6%, while outpatient visits for flu-like illness have reached 7.8%, both exceeding the national baseline for the tenth consecutive week. Flu activity is classified as very high or high in 45 jurisdictions across the country. The CDC estimates that this season has already seen 24 million flu infections, 310,000 hospitalizations, and tragically, 13,000 deaths.
While all age groups are susceptible, the CDC notes that emergency department visits for flu are particularly high among children and adolescents up to 17 years old. The report also includes the grim news of 10 additional pediatric flu deaths, bringing the total for the season to 57.
The dominant strain of influenza this season is influenza A, accounting for 97.4% of positive tests. Within influenza A, the sub-strains are split, with 53.7% being H3N2 and 46.3% being 2009 H1N1.
While the flu continues to be a major health concern, the CDC report also provides an update on other respiratory viruses. COVID-19 activity remains elevated, particularly in the Northeast, which is currently experiencing the nation’s highest levels of the virus in wastewater. Conversely, Respiratory Syncytial Virus (RSV) rates are showing a decline.
This flu season’s impact on older adults underscores the importance of vaccination, infection control protocols, and vigilant monitoring within nursing home facilities. As the season progresses, staying informed about the latest CDC updates and implementing best practices will be crucial in protecting vulnerable residents.
