Pertussis (whooping cough) can cause serious illness in babies, children, teens, and adults. Symptoms of pertussis usually develop within 5 to 10 days after you are exposed. Sometimes pertussis symptoms do not develop for as long as 3 weeks. The disease usually starts with cold-like symptoms and maybe a mild cough or fever. In babies, the cough can be minimal or not even there. Babies may have a symptom known as “apnea.” Apnea is a pause in the child’s breathing pattern. Pertussis is most dangerous for babies. About half of babies younger than 1 year who get the disease need care in the hospital.

Early symptoms can last for 1 to 2 weeks and usually include:

  • Runny nose
  • Low-grade fever (generally minimal throughout the course of the disease)
  • Mild, occasional cough
  • Apnea – a pause in breathing (in babies)
The Centers for Disease Control and Prevention (CDC) offers many resources for healthcare professionals.
