Overview
- The Health Ministry confirmed six influenza A (H3N2) infections linked to subclade K and said epidemiological surveillance is being reinforced.
- An updated vaccine batch tailored to subclade K is slated to arrive in early February—about two months earlier than usual—under a fully paid contract for high‑risk groups.
- Doses are earmarked for older adults, young children and people with comorbidities, and authorities clarified these vaccines are distinct from Covid‑19 shots.
- Infectious‑disease experts say the variant is highly contagious without evidence of greater severity so far, recommending vaccination and standard respiratory precautions.
- Regionally, Argentina has confirmed pediatric cases and other countries are investigating possible infections, while health officials in Sonora, Mexico, report current vaccines offer protection and continue to urge uptake.
