Overview
- Mexico’s Health Ministry said INER confirmed the country’s first influenza A(H3N2) subclade K case, and the patient recovered following standard outpatient antiviral treatment.
- WHO and PAHO report expanding H3N2 activity with a growing share of subclade K in North America, Europe and parts of Asia based on recent surveillance updates.
- Health authorities state the subclade’s clinical picture matches seasonal influenza, with no documented rise in hospitalizations, ICU admissions or deaths.
- Mexico and partners are sustaining active surveillance through systems such as SINAVE and are urging vaccination for priority groups alongside early care, standard antivirals when indicated, masking when symptomatic and isolation as needed.
- Peru’s Health Ministry and regional directorates report no detection of subclade K in South America, rate national risk as low to moderate and are reinforcing monitoring and vaccine access.
