A sweeping new study from Sweden is challenging the widespread belief that higher physical fitness in young people directly leads to a substantially lower risk of premature death from diseases like cancer and heart disease—a notion that has shaped public health messaging globally, including in Thailand. The research, published in the European Journal of Preventive Cardiology (news-medical.net), reveals that previous studies may have overstated the true impact of physical fitness on mortality due to overlooked differences among individuals.

The well-held belief that physical fitness in youth directly causes a lowered risk of early death is being challenged by new research from Uppsala University, which suggests that the true relationship between fitness and mortality may be far more complex than previously thought. The findings, published in the European Journal of Preventive Cardiology, reveal that even random factors—such as accidents—show similar associations to fitness and premature death as diseases, raising questions about the validity of past conclusions on the protective effects of fitness alone.

Three more US states—Louisiana, Virginia, and Missouri—confirmed their first measles cases of 2025 over the weekend, pushing the current outbreak to over half of all US states and marking one of the most significant resurgences in recent years. According to a report by UPI, the total number of confirmed cases across at least 27 states has climbed to 800, with the vast majority being either unvaccinated or of unknown vaccination status. This growing crisis reflects deeper global trends in vaccine coverage and highlights crucial public health lessons for Thailand, where measles cases have also risen sharply over the last two years (UPI, CDC).

A recent discovery in Greenville, North Carolina has put public health surveillance techniques in the spotlight: wastewater samples from a local sewage plant have tested positive for Mpox, the virus formerly known as monkeypox, specifically identifying the clade I strain. The samples, collected between late March and early April, point to the potential presence of the virus in the community, even though no clinical Mpox cases have been officially reported so far. Local health officials are now urging healthcare providers to be vigilant for possible symptoms and to quickly report any suspected infections (WRAL; ABC11).
