Pertussis Cases Triple in Texas Amid National Surge in 2024

In November 2024, the Texas Department of State Health Services (DSHS) reported a substantial increase in pertussis (whooping cough) cases, with the same period of last year's figures nearly tripling. According to preliminary data, the number of cases has increased by over fivefold nationally.

Pertussis, caused by the Bordetella pertussis bacteria, has cold-like symptoms that progress to severe coughing spells, occasionally accompanied by vomiting or a distinctive "whoop" sound. Infants frequently exhibit various symptoms, including gasping, gagging, or turning pale.

Vaccination is the most effective preventative measure, according to health officials. Nevertheless, more than half of the Texas cases in 2024 have been reported in individuals who have received at least one vaccine dose, and a third have been reported in those who have received all three vaccines.

Antibiotics, including azithromycin and erythromycin, are most effective when administered within three weeks of the onset of symptoms. Treatment should be administered within six weeks to pregnant women and infants under one year of age.

Before visiting a clinic, individuals who exhibit symptoms should isolate and notify their healthcare provider to prevent the spread. Hand washing and cough covering are still essential sanitation practices.

The resurgence of pertussis results from the abnormally low case counts during the COVID-19 pandemic. In Texas, the number of cases has now returned to the pre-pandemic level of over 1,400 annually.

Consult with healthcare providers regarding vaccination or post-exposure antibiotics to mitigate risk and severity, and review your family's immunization records.
