When should I call the doctor about my child's whooping cough (pertussis)?

If your child has not yet had pertussis, call your child’s doctor if he has:
  • Been exposed to someone with pertussis or if you think he may have
          pertussis, even if he has had his vaccines.
  • A cough that lasts longer than a week and he has not yet been seen
          by a doctor.
  • A cough that causes vomiting or breathing problems.
  • A cough that has a whooping sound when he breathes in.

If your child is being treated for pertussis, call your child’s doctor if:

  • Your child has persistent lethargy or irritability (does not smile or
          show interest in play for at least a few minutes during a
          four-hour period).
  • Your child wheezes or breathes harder than he did when he was
          seen by the doctor.
  • Your baby is unable to breathe and suck at the same time or chokes
          when he sucks.
  • Your child has fast, shallow breathing.
  • Your child has a tight feeling in the chest.
  • You see signs of dehydration (drying out):

        - No urine in six to eight hours in an infant less than 1 year of age
        - No urine in more than eight hours in a child older than 1 year of  
           age
        - No tears when crying
        - Sunken eyes
        - Dry lips and mouth

  • Your child has a fever over 100.4°F
  • Your child is unable to keep fluids down or vomits more than twice a
          day.
  • You have any concerns about how your child looks or feels.

 Call 911 or your local ambulance service right away if your child:

  • Is so lethargic that he hardly responds to you
  • Is working very hard to breathe or finds it hard to take a breath
  • Has chest retractions (skin pulling in around the ribs and chest when
          breathing)
  • Grunts when he breathes
  • Has a blue or dark purple color to the nail beds, lips or gums
  • Stops breathing for more than 5 seconds
  • Cannot speak while trying to breathe
  • Has any breathing problem that needs care right away.
