In a paper publishing in the Cell Press journal Trends in Immunology on December 4, scientists and doctors highlight the importance of studying long COVID in the context of other post-acute infection syndromes or chronic illnesses. By analyzing historical accounts of other epidemics, they say, researchers can gain important perspective on the profound effects of these chronic illnesses—with the goal of informing more effective interventions for treating them. 

By a 2-1 margin, the public would be more likely to accept the recommendation of the American Medical Association (AMA) than the Centers for Disease Control and Prevention (CDC) on vaccine safety, an Annenberg survey finds. The survey finds that that that is true regardless of political party identification. Just over half of Americans say the CDC is providing trustworthy information on vaccine safety and effectiveness.

New study examines the oral pathogen Porphyromonas gingivalis (Pg) and suggests its influence may extend beyond dental tissues. Researchers investigated whether Pg-driven periapical lesions, localized dental issues, can trigger wider metabolic disturbances through an IL-17–intense inflammatory response. Using sham-controlled mouse models without oral colonization, the researchers compared mice with and without Pg colonization to assess how IL-17 drives both tissue damage and impaired glucose regulation. The study examines whether chronic periapical infections subtly shape metabolic health and whether targeting IL-17 could offer unexpected systemic benefits.

As summer festivals and youth gatherings return in full swing, new research from Flinders University is revealing the hidden health risks that come with multi-day events, and how to avoid them. A comprehensive review led by public health experts to identify and understand the risks that occur at multi-day events reveals that infectious disease outbreaks and foodborne illnesses are the most common public health threats at youth-focused mass gatherings.
