Texas Pertussis Cases Surge; CDC Recommends Vaccines

The Texas Department of State Health Services (DSHS) has issued a health alert due to a dramatic increase in pertussis cases, reporting over 3,500 cases in 2025, which is approximately four times the number reported for the same period in the previous year. This marks the second consecutive year of significant year-over-year increases and the second consecutive year DSHS has issued a health alert for pertussis. The alert highlights that pertussis activity has rebounded significantly after a dip during the COVID-19 pandemic, with preliminary data indicating that about 85 percent of cases this year have occurred among children.

Healthcare providers are urged to consider pertussis in patients with compatible symptoms and report suspected cases to local health departments within one business day. The DSHS strongly reiterates that vaccination is the most effective preventive measure against pertussis. Parents are advised to ensure children are up-to-date on their immunizations, and pregnant women and individuals who will be around newborns should receive a booster dose. The CDC's recommendations for pertussis vaccines for people of all ages are emphasized, noting that protection from vaccination fades over time and thus, all individuals should stay current with their vaccinations.
