The U.S. Centers for Disease Control and Prevention (CDC) has issued a public health alert for a new influenza strain, provisionally named "Flu-X," first identified in laboratory samples from several U.S. states, including California, New York, and Texas, as of February 11, 2026.

The alert highlights the need for enhanced surveillance and vaccination efforts, as early data suggests Flu-X may disproportionately affect vulnerable populations, with the World Health Organization (WHO) preparing to convene an emergency committee to assess the risk.
