CDC Warns of Bird Flu Pandemic Risk Amid Seasonal Flu Vaccine Push
The Centers for Disease Control and Prevention (CDC) has urged the public to consider getting the seasonal influenza vaccine as a precaution against a possible bird flu pandemic. Recently, the U.S. has reported 66 human infections of H5N1 bird flu across 10 states in 2024, with the majority of cases found in California. One fatality has been confirmed in Louisiana.
The CDC notes that while bird flu itself does not typically spread from person to person, the potential for a pandemic exists if H5N1 viruses genetically shift by co-infecting humans with other influenza viruses. Vaccination can lower the risk of co-infections, which could lead to the emergence of new viruses.
Currently, the general risk of avian influenza to public health is considered low, as no person-to-person transmission has been detected. However, the CDC emphasizes the importance of vaccination, especially for those with frequent exposure to potentially infected birds.
As of December 14, about 40% of U.S. adults and children had received their seasonal flu shots, which is lower than recommended immunization rates. The CDC continues to prepare for potential outbreaks by developing candidate vaccine viruses in anticipation of a pandemic.
