Texas health officials have sounded the alarm over a significant surge in whooping cough cases, with over 3,500 infections reported as of October 2025—nearly four times the number from the previous year.
This marks the second consecutive year with unusually high cases, prompting the Texas Department of State Health Services (DHSH) to issue health alerts and urge enhanced vaccination efforts. The condition, also known as pertussis, is a bacterial infection that progresses from mild cold-like symptoms to severe coughing fits, posing the greatest risk to infants under 12 months old, who may experience breathing difficulties without the classic ‘whoop’ sound.
Officials stress that timely vaccination remains critical to preventing outbreaks and protecting vulnerable populations. The Centers for Disease Control and Prevention (CDC) recommends that all age groups receive pertussis vaccinations to maintain immunity, as booster shots are essential for those whose protection has waned over time.
Additionally, health leaders emphasize that pregnant women should receive the Tdap vaccine during each pregnancy, ideally between the 27th and 36th weeks, to safeguard newborns. Adults in close contact with infants are also advised to be vaccinated at least two weeks before potential exposure, further reducing the risk of transmission.
Clinicians are encouraged to test anyone showing symptoms consistent with pertussis, though treatment can begin based on “strong clinical suspicion” or exposure. PCR tests are preferred due to their speed and availability. Early treatment—regardless of vaccination history—is key to preventing severe illness and halting the spread of the disease.
While adults may typically experience milder symptoms, infants and unvaccinated individuals remain at the highest risk for complications, including hospitalization and severe health outcomes. The DHSH reiterates the importance of community immunity and widespread vaccination to curb the spread of the infection and protect public health.
