Know the FACTS about pertussis
  • Pertussis is also known as "whooping cough" because of the "whooping" sound that is made when gasping for air after a fit of coughing.
  • Coughing fits due to pertussis infection can last for up to 10 weeks or more; this disease is sometimes known as the "100 day cough."
  • Pertussis can cause serious illness in babies, children, teens, and adults and can even be life-threatening, especially in babies.
  • Approximately half of babies less than 1 year old who get pertussis need treatment in the hospital.
  • The most effective way to prevent pertussis is through vaccination with DTaP for babies and children and with Tdap for preteens, teens, and adults.
  • Vaccination of pregnant women with Tdap is especially important to help protect babies.
  • Vaccinated children and adults can become infected with and spread pertussis; however, disease is typically much less serious in vaccinated people.
  • Pertussis is generally treated with antibiotics, which are used to control the symptoms and to prevent infected people from spreading the disease.
