Overview
- Argentina’s National Epidemiological Bulletin reports 2025 pertussis cases have tripled versus 2024, with 63 confirmed and 252 probable cases counted through week 40.
- The Buenos Aires provincial health ministry issued an epidemiological alert and moved to reinforce surveillance and vaccination across schools and clinics.
- Authorities confirmed at least four pediatric deaths in the province this year; three infants were not appropriately vaccinated and one newborn lacked protection because the mother was not immunized during pregnancy.
- Clinical guidance calls for early macrolide treatment—commonly azithromycin for five days—plus antibiotic prophylaxis for close contacts to curb transmission.
- Public recommendations include keeping children under seven with persistent cough out of school until completing five days of adequate antibiotics and ensuring routine childhood doses and vaccination in each pregnancy.
