# Argentina hantavirus source-linked case summary

Argentina official 2026 surveillance update

## Summary

Argentina’s Ministry of Health reported 42 hantavirus cases notified so far in 2026 and 101 confirmed notifications since epidemiological week 27 of 2025, while describing national coordination after the MV Hondius cruise-associated outbreak.

## Safe interpretation

Counts are an official national notification snapshot, not a live case feed. No patient locations or local-risk map are inferred from the national update. The broader 101 confirmed notifications since SE 27 of 2025 are retained in text only, not mixed into the 2026 year-to-date case field.

This record is a reviewed public health map note. It is not live surveillance, medical advice, patient-location tracking, or county-level risk prediction.
