Pertussis, commonly referred to as whooping cough, is an extremely contagious respiratory tract infection. In the beginning stages, pertussis may appear similar to an ordinary cold. However, it may eventually turn more serious, especially for an infant.
Current Status: The CDC has reported a state-wide epidemic of whooping cough for the state of California. If you are unsure whether or not your child has been vaccinated, please check with your doctor. If you are an adult or have teenagers you would like to receive the booster shot, please contact your doctor’s office and ask for an appointment to receive a Tdap vaccine.
Contagious: Pertussis is the most contagious before the coughing even begins. It is most contagious in the early, runny-nose stage but can remain contagious for the first 3 weeks. Symptoms may appear 6-21 days after exposure. After 5 days on an effective antibiotic treatment, pertussis is no longer contagious.
Symptoms of Pertussis: Early symptoms of pertussis are similar to a cold, with runny nose; sneezing and coughing that may progress to a persistent coughing. Fits of coughing may be followed by a gasp for air (whooping). Coughing attacks may also lead to vomiting. Pertussis can last for 6-10 weeks. However, older children, adults and very young infants may not develop the whoop.
Prevention: The spread of pertussis to children can be prevented with a vaccination called DTap, which is a routine childhood vaccination, although state requirements for the vaccine vary. For young adults and adults, there is a booster vaccine called Tdap, which is commonly given to prevent tetanus, but also prevents whooping cough and diphtheria.
