Texas health officials are sounding the alarm on a surge of a common childhood illness, with cases of whooping cough nearly quadrupling compared to the same period last year. The Texas Department of State Health Services (DHSH) has reported over 3,500 infections through October 2025, triggering health alerts and urging vaccinations to curb the spread of the highly contagious respiratory infection.
Pertussis, also known as whooping cough, is caused by the bacterium Bordetella pertussis and is typically characterized by initial cold-like symptoms, followed by severe coughing fits that may culminate in a high-pitched ‘whoop’ as the afflicted individual gasps for air. The illness progresses through three stages, beginning with symptoms similar to a common cold, transitioning to violent coughing, and ultimately leading to gradual recovery. While the infection can affect people of all ages, the most severe complications are observed in infants under 12 months, who are at a higher risk of hospitalization and life-threatening complications if not vaccinated.
Health officials emphasize that while teenagers and adults can contract whooping cough due to waning immunity, the symptoms are usually milder. To mitigate risks, the CDC recommends vaccinations for all age groups, with a specific focus on pregnant women who should receive a Tdap shot between 27 and 36 weeks of gestation. Additionally, adults in close proximity to infants are advised to be vaccinated at least two weeks prior to any potential exposure.
Clinicians are being urged to test individuals exhibiting symptoms consistent with pertussis, and treatment can commence based on strong clinical suspicion or exposure. PCR tests are preferred due to their rapid availability and accuracy. Early treatment is crucial in preventing severe outcomes and curtailing the spread of the infection. Health officials are working to raise awareness about the importance of vaccination and maintaining up-to-date immunization records to protect vulnerable populations, especially young children and pregnant women.
