Overview
- Mexico’s National Institute of Respiratory Diseases (INER) identified the case, which was managed with outpatient antivirals, and the patient has recovered.
- The Health Ministry says the virus shows seasonal flu–like behavior, clinical management remains the same, and it is not a cause for alarm, with SINAVE maintaining active monitoring.
- WHO/PAHO have warned of increased circulation of the H3N2 K subclade, widely detected in Europe and East Asia with growing presence in the United States and Canada.
- Peru’s Health Ministry rates the current risk as low to moderate, has activated surveillance ahead of year‑end travel, and reports sufficient vaccine supply for priority groups.
- Specialists note current seasonal vaccines do not include K-specific antigens, which may reduce strain-specific protection, yet vaccination still helps prevent severe illness, and Peru reports no detections of K to date.
