The CDC notes that while these strains are resistant to Tamiflu, they remain susceptible to other antiviral drugs like baloxavir. This highlights the need for alternative treatments.
Expert Insights on the Mutation
Dr. Marc Siegel from NYU Langone Medical Center emphasized the unusual timing of the flu’s spread, noting that flu season typically ends by March.

He expressed concerns about the reduced effectiveness of Tamiflu but still recommends its use for its partial benefits and suggests considering other anti-flu drugs.
Historical Context and Evolution
The dual mutant strains I223V and S247N were first tested by Hong Kong scientists and published in The Lancet Microbe in March 2024.

These strains have shown to lessen the effectiveness of Tamiflu, underscoring the importance of continuous monitoring and research to understand their evolution.
CDC's Ongoing Surveillance
The CDC’s study shows the importance of closely monitoring these dual mutants. Researchers warn that additional changes in the virus could further affect drug susceptibility or give the virus an advantage over wild-type strains.
