Overview
- Confirmed infections doubled in six weeks, rising from 333 before mid‑October to 688 in the latest national bulletin.
- Authorities logged 5,110 suspected cases with an incidence of 1.45 per 100,000, and 586 confirmations had conclusive lab evidence with 81.9% identifying Bordetella pertussis.
- Cases are reported in 20 jurisdictions with concentration in the Centro and Sur regions, driven by increases in Buenos Aires Province and a persistent Tierra del Fuego outbreak.
- All seven deaths occurred in children under two years old; four age‑eligible children had no vaccine doses recorded in NOMIVAC and the three younger than two months had no recorded maternal vaccination.
- Officials highlight wide provincial disparities in routine and booster coverage and note that some jurisdictions report about 40% of infections in infants under one, reinforcing calls to raise childhood and pregnancy vaccination.
