Current State of the Flu Season in the U.S.
The flu season in the United States seems to be at its peak, with a noticeable decline in reported cases and hospitalizations. According to the latest U.S. Influenza Surveillance Report, updated on January 12, 2024, seasonal influenza activity remains elevated in most parts of the country. The most frequently reported influenza viruses are influenza A H1N1 pdm09. The cumulative hospitalization rate and the number of deaths attributed to influenza are also included in this report. Additionally, virologic surveillance data provides information on influenza virus characterization and assessment of virus susceptibility to antiviral medications.
Monitoring Respiratory Illnesses
The U.S. Outpatient Influenza-like Illness Surveillance Network (ILINet) monitors outpatient visits for respiratory illnesses referred to as influenza-like illness (ILI). The ILINet captures respiratory illness visits due to infections with pathogens that can present similar symptoms, including influenza viruses, SARS-CoV-2, and RSV. However, the current flu season in the U.S. has not yet reached its peak and is expected to peak around the end of January or February. Simultaneously, COVID-19 transmission remains steady, with hospital admissions increasing and deaths rising.
The Impact of Flu and COVID-19
The flu season in the U.S. is amplifying, with 38 states reporting high or very high levels of respiratory illnesses. Data from the CDC indicates that COVID-19 is putting more people in the hospital than the flu, raising concerns about the current surge of COVID-19 and its peak. Additionally, the predominant variant of COVID-19 circulating in the U.S., known as JN.1, carries mutations that allow it to escape immunity better. It’s important to mention that low vaccination rates for both the flu and COVID-19 could intensify the severity of this flu season.
CDC’s Report on Influenza and Other Illnesses
Recent CDC data indicates an 18% increase in people testing positive for influenza last week. Additionally, 21 states and New York City are experiencing very high levels of sickness. Hospital admissions for COVID have also jumped 20% in the last week, and more people are testing positive for RSV. It’s predicted that the flu season hasn’t peaked yet, and the majority of states are seeing high or very high levels of sickness. So far, this flu season, the CDC estimates there have been at least 10 million illnesses, 110,000 hospitalizations, and 6,500 deaths.
Preventive Measures During Flu Season
While the peak of the flu season may have been reached, health experts stress the importance of remaining vigilant. Vaccination is the most effective way to protect against these viruses. Other preventive measures include practicing good hygiene, such as washing hands regularly and wearing masks. It is essential to continue monitoring the situation as the flu season progresses, considering the concurrent circulation of other respiratory pathogens like SARS-CoV-2 and RSV. With collective effort and adherence to preventive measures, the impact of the flu season can be mitigated.
