Перевод whooping cough (pertussis). a newborn baby has no immunity to this disease at all, and so he must be kept protected from children who have any kind of cough. whooping cough seems like an ordinary cough for the first few days, but gradually the bouts become more and more prolonged and the child coughs continuously. his face becomes red and he very often vomits. at the end of the bout of cough, when he tak es a deep breath, a croaky sound is heard which is called the whoop and which gives the disease its name. the disease is a prolonged one and the cough may last2—3months. it can lead to lung complications also. the child loses weight because of repeated vomiting. fortunately, it can be prevented by immunizing the child with triple antigen (dpt) injections. a child with whooping cough should be kept separate from other children for the first 3—4weeks, but it is very often difficult to do that because of shortage of space in the house. the disease is more severe in babies under 1 year of age, and every effort must be made to isolate them, at least.
