Diphtheria, tetanus, and pertussis are contagious diseases that can be prevented with immunizations. Talk to your doctor about the immunization schedule for your child.

Diphtheria

  • Diphtheria is spread among unimmunized people living in crowded conditions by coughing or sneezing.
  • Unimmunized children under 5 years of age are more likely to contract diphtheria.
  • Diphtheria can cause breathing and heart problems, and even death.
