New Options for Gonorrhea Treatment

In December 2025, the Food and Drug Administration (FDA) approved two new antibiotics to combat uncomplicated urogenital gonorrhea, a common sexually transmitted infection caused by the bacterium Neisseria gonorrhoeae. Zoliflodacin (Nuzolvence) is a first-in-class antibiotic, requiring only a single oral dose for treatment. Gepotidacin (Blujepa) received FDA approval in March 2025, initially for uncomplicated urinary tract infections, and is effective against strains of Escherichia coli, Klebsiella pneumoniae, Citrobacter freundii complex, Staphylococcus saprophyticus, and Enterococcus faecalis.

Updated Immunization Guidance

The American Academy of Pediatrics (AAP) released the Recommended Childhood and Adolescent Immunization Schedule: United States, 2026 on January 26, 2026. This schedule provides guidance on routine vaccinations to protect against 18 infectious diseases, including RSV, hepatitis A and B, rotavirus, influenza, and meningococcal disease. The detailed schedule is available in AAP Red Book Online, the academy’s comprehensive resource for infectious disease prevention and treatment. A parent-friendly version of the schedule can be found on HealthyChildren.org.

HIV Funding Protected

Congress has preserved funding for domestic HIV programs in the final FY2026 spending bill. The Appropriations Committees rejected a House Republican proposal that would have cut over $1.7 billion from these programs, including eliminating all HIV prevention initiatives and reducing funding for the Ryan White HIV/AIDS Care and Treatment Program by 20 percent, or $525 million.

UTI Treatment and Patient Education

Research suggests a link between patient education levels and treatment outcomes for uncomplicated urinary tract infections (UTIs). A study by Jacinda Abdul-Mutakabbir, PharmD, MPH, assistant professor of clinical pharmacy and antimicrobial resistance researcher at UC San Diego, found a correlation between higher levels of education and increased rates of treatment failure. Interestingly, the study also observed less treatment failure among Black and Hispanic patients treated with cephalosporins, prompting further investigation into the role of insurance coverage and other factors.
