Overview
- Provisional data show more than 3,500 pertussis cases through October 2025, nearly four times last year’s count.
- This is the second consecutive year Texas has recorded sharp increases and prompted a statewide health alert.
- Roughly 85% of reported infections are in children, with at least two infant deaths and a high risk of hospitalization for babies under one.
- Clinicians are being asked to use PCR testing, start antibiotics based on strong suspicion or exposure, and provide post-exposure prophylaxis to limit spread.
- Health leaders emphasize staying current on DTaP/Tdap, with Tdap recommended at 27–36 weeks of each pregnancy, as doctors warn winter respiratory viruses could compound risks.
