A roundup of health news highlights a boost in Medicare Advantage reimbursement rates, Mexico's first human death from H5N1 avian flu, a Texas probe into WK Kellogg's health claims, and Viatris's opioid settlement. Discussions on fluoride in drinking water and more are also covered.

In a significant development, U.S. health insurers saw their stocks rise sharply following the announcement of a 5.06% increase in 2026 Medicare Advantage reimbursement rates. This uptick exceeded initial projections, impacting premium charges and plan benefits offered by private insurers managing healthcare under Medicare.

Tragedy struck in Mexico as authorities reported the first human fatality due to H5N1 avian influenza. A three-year-old girl in Coahuila succumbed to the virus, raising concerns over the potential spread of the bird flu to humans.

In other news, Texas has launched an investigation into WK Kellogg's cereal products, scrutinizing claims of their health benefits amid allegations they contain harmful artificial colorings. Meanwhile, Viatris agreed to up to $335 million in opioid-related settlements, and the U.S. Health Department plans new fluoride recommendations for drinking water.
