Austin Public Health on Thursday reported more than 130 pertussis, or whooping cough, cases in Austin-Travis County so far this year, a 58 percent increase compared to the same period in 2024.
Health officials said the increase appears connected to higher transmission in the community. Pertussis is a respiratory disease that can cause severe illness, especially in infants, pregnant people, and individuals with weakened immune systems.
Austin Public Health said clinicians diagnose pertussis through symptoms and laboratory testing. Confirmed cases involve patients of different ages in multiple areas of the county.
Officials said early symptoms may include a runny nose, mild cough, and low-grade fever. The illness can later involve strong coughing fits that may produce a “whooping” sound or lead to vomiting after coughing.
Austin Public Health said the case count reflects reports from healthcare providers, laboratories, and schools and will change as new information comes in.
The department said pertussis can cause complications such as pneumonia in young children. Infants under 12 months face the highest risk of hospitalization.
Austin Public Health said vaccination remains the main preventive measure. The DTaP vaccine is recommended for children, and the Tdap booster is recommended for adolescents, adults, and pregnant people during each pregnancy.
Health officials encouraged residents to review their vaccination records with their healthcare providers. Vaccines are available at clinics, doctors’ offices, and other authorized locations in the county.
Austin Public Health said it monitors pertussis activity with state health authorities and uses case data to identify clusters and guide outreach.
The department said it has informed medical providers, schools, and childcare facilities of the rise in cases and has issued guidance on symptoms, testing, treatment, and infection control.
Officials said individuals diagnosed with pertussis should follow medical instructions, complete prescribed antibiotics, and remain home during the contagious period.
Austin Public Health said it will continue monitoring pertussis trends in 2025 and may release further updates as new information becomes available.
