Health officials in Texas have raised the alarm over a dramatic increase in whooping cough cases, with data showing nearly four times the number of infections compared to the previous year. Over 3,500 cases have been reported through October 2025, marking the second successive year of a notable spike. This surge has led to health alerts across the state, with a strong emphasis on vaccination as a key preventative measure.
The Texas Department of State Health Services (DHSH) announced the latest figures, highlighting the urgent need for public awareness and action. Pertussis, also known as whooping cough, is a bacterial infection caused by Bordetella pertussis, which is highly contagious and can progress from mild cold-like symptoms to severe coughing fits. The illness has three distinct stages, beginning with symptoms similar to a common cold and evolving into intense coughing spells that may result in a high-pitched ‘whoop’ during inhalation.
While children are the most susceptible, particularly infants under one year old, the infection can affect individuals of all ages. Complications are most severe in babies, with the risk of hospitalization and increased mortality for immunocompromised or unvaccinated infants. Teenagers and adults, though usually experiencing milder symptoms, are also at risk due to waning immunity from past vaccines.
Health officials are stressing the importance of vaccination for all age groups, especially pregnant women, who are advised to receive a Tdap shot during each pregnancy to protect newborns. Close contacts of infants should also be vaccinated at least two weeks before potential exposure to ensure protection. Clinicians are encouraged to conduct PCR tests for suspected cases, as early treatment is critical in preventing severe illness and containing the spread of the infection.
The Centers for Disease Control and Prevention (CDC) recommends routine pertussis vaccinations for everyone, emphasizing the need to maintain up-to-date immunity to prevent resurgence. As the state continues to monitor the outbreak, public health measures are being reinforced in the hope of curbing the spread and mitigating the impact of this preventable yet potentially deadly illness.
