The mechanism of transfer of the stimulator is an air-droplet. The infection is spread from an infected person to susceptible people. The disease is highly contagious: the probability of close contact with the patient is 80% or more. Transmission through infected objects is rare. During infection, the pertussis bacillus penetrates the mucous membrane of the respiratory tract and increases the secretion of mucus, which over time becomes viscous and thick. Toxin produced by bacteria causes spastic cough.

Other complications may develop against the background of the disease. Possible consequences of whooping cough: pneumonia, respiratory arrest, cerebrovascular disorder, convulsions, intracranial bleeding, and others.

Prevention

Prognosis is good, but the disease lasts a long time. Current clinical recommendations for disease prevention include pertussis vaccination. The vaccine is given to children three times in the first year of life, at the age of 3 months, 4.5 months and 6 months, and then revaccination is done at 18 months. Then the pertussis component is no longer introduced.
