Pertussis Cases in Travis County

What is pertussis?

.Pertussis, also known as whooping cough, is highly contagious respiratory disease by bacteria. It is known for uncontrollable, violent coughing which often makes it hard to breathe. After fits of many coughs, someone with pertussis often needs to take deep breaths, which results in a “whooping” sound. Pertussis most commonly affects infants and young children and can be fatal, especially in babies less than one year of age.

From October 1, 2009 through January 14, 2011, A/TCHHSD identified 1,191 confirmed and probable pertussis cases. Epidemiologic investigation of this preliminary data shows that 79.5% of the cases reported between October 1, 2009 and January 14, 2011 have reported receiving at least one pertussis vaccination.

Since October 2009, 37 children and 4 adults have been hospitalized with confirmed or probable pertussis. The most common presenting symptoms include persistent cough (lasting over 14 days) and paroxysmal cough (coughing fits and spasms) with vomiting.

To prevent pertussis:

  • Frequent hand washing, covering your cough and hand sanitizers when hand washing is unavailable;
  • Seeing your doctor immediately if you suspect that you or a family member has pertussis;
  • Protecting infants from coughing children and adults;
  • Starting childhood vaccinations on time and staying on schedule using a vaccine called DTaP, which contains diphtheria, tetanus and acellular pertussis vaccines;
  • Boosting immunity to pertussis using a vaccine for adolescents and adults called Tdap, which contains pertussis vaccine as well as tetanus and diphtheria vaccines.

If you or family members are diagnosed with pertussis it is critical that you follow all public health instructions which include:

  • Refraining from contact outside the home for the first 5 days of treatment with antibiotics. Children must not return to school or childcare until after they have completed 5 days of antimicrobial treatment.
  • Persons diagnosed with pertussis and individuals identified as a contact to a pertussis case should take all medication as directed.
