'Dual mutant' flu virus that may defy antiviral medication is warned about by the CDC: "Need to keep a close eye on".

The two strains were shown to be resistant to Tamiflu, researchers found

As to the Centres for Disease Control and Prevention (CDC), there may be a threat from a novel strain of H1N1 influenza known as "dual mutant" in the United States. Specifics regarding the two strains, I223V and S247N, were released in the CDC journal Emerging Infectious Diseases. According to the CDC, at least two cases of the flu mutations have been verified in people in the United States as of Wednesday.

According to Modena, the COVID-19 combo vaccine is showing "positive" outcomes in phase three trials. A "TWO-FOR" CHOICE A total of 101 samples of the "dual mutant" virus were found by the researchers. The reason for concern is that some flu strains have demonstrated resistance to the antiviral drugs that are usually prescribed to treat the virus, most notably Roche's Tamiflu (oseltamivir), a popular flu treatment located in Switzerland.

According to the study results, "the dual mutants that we tested retained susceptibility to other approved influenza antiviral drugs, including baloxavir," the researchers noted. ALERTED, NOT ALARMED: CDC AND WEBMD PROVIDE UPDATES ON THE CURRENT BIRD FLU OUTBREAK. "Our study highlights the need to closely monitor the evolution of dual mutants, because additional changes may further affect susceptibility to antiviral drugs or provide a competitive advantage over circulating wild-type viruses."

The mutations have been circulating worldwide since May 2023, the researchers found. Scientists from Hong Kong conducted the initial testing on I223V and S247N, and in March 2024 they published their results in The Lancet Microbe.

It is "very unusual," according to Dr. Marc Siegel, clinical professor of medicine at NYU Langone Medical Centre and medical contributor to Fox News, to witness an influenza A strain (H1N1, he noted—a distant relative of the Spanish flu—spreading throughout the southern U.S. states during this time of year.

According to Siegel, "Flu season usually ends by March," Fox News Digital reported. "Flu doesn't spread as easily in hot, humid weather." He continued, "This mutation worries me because the use of Tamiflu — especially in high-risk groups and the elderly — is really helpful at decreasing severity, and it looks like the reaction to it is less."
