Explanation
•Pertussis is a highly contagious bacterial infection. It causes severe coughing fits (whooping cough) and vomiting that can last up to 6 weeks.
•Pertussis can be prevented with Dtap, a vaccine for tetanus, diphtheria, and pertussis. Once contracted, pertusis is treated with antibiotic therapy.
•Mycoplasma pneumonia, Rocky Mountain spotted fever, and rickettsia do not cause a whooping cough.
