Symptoms

By Mayo Clinic staff

Once you become infected with whooping cough, it takes three to 12 days for signs and symptoms to appear. They're usually mild at first and resemble those of a common cold:

  • Runny nose
  • Nasal congestion
  • Sneezing
  • Red, watery eyes
  • A mild fever
  • Dry cough

After a week or two, signs and symptoms worsen. Severe and prolonged coughing attacks may:

  • Bring up thick phlegm
  • Provoke vomiting
  • Result in a red or blue face
  • Cause extreme fatigue
  • End with a high-pitched "whoop" sound during the next breath of air

However, many people — particularly infants, adolescents and adults — don't develop the characteristic whoop. Sometimes, a persistent hacking cough is the only sign that an adolescent or adult has whooping cough.

When to see a doctor
Call your doctor if prolonged coughing spells cause you or your child to:

  • Vomit
  • Turn red or blue
  • Inhale with a whooping sound
