What Are Diphtheria, Tetanus, and Pertussis?
Diphtheria is an infection caused by toxins produced from the Corynebacterium diphtheriae bacteria. Diphtheria is transmitted from person to person through droplets from coughing or sneezing. Diphtheria can lead to difficulty breathing, heart failure, paralysis, or death.
Tetanus, commonly called lock jaw, is an infection caused by the Clostridium tetani bacteria. People get tetanus when bacterial spores enter through broken skin. Tetanus causes painful stiffening of the muscles. Serious health problems include being unable to open the mouth, having trouble swallowing or breathing, or death.
Pertussus, commonly called whooping cough, is a very contagious respiratory illness caused by the Bordetella pertussis bacteria. Whooping cough is transmitted from person to person through the air through coughing and sneezing, or by sharing a breathing space. Whooping cough can cause violent coughing that makes it hard to breathe, eat, or drink. It is especially serious in babies and young children as it can cause pneumonia, convulsions, brain damage, or death.

- 2 months
