[The epidemiology of whooping cough].
Due to a low acceptance of active immunisation against Bordetella pertussis, whooping cough continues to be a frequent childhood disease in parts of Germany. The age distribution in the lower Rhine area showed a peak incidence at 4.3 years of age, whereas 11% of all cases were observed in infants, and 6% were observed in adults. A significant sex difference was not found in children suffering from pertussis; in adult patients, however, women were more often affected. Whooping cough occurred during the whole year, its peak incidence was found during early winter. In children, paroxysmal coughing fits, vomiting and whooping were the primary symptoms of disease; adults and infants, however, developed these symptoms only in reduced frequency. About 25% of all cases showed an atypical course, and could only be diagnosed by laboratory tests. While leukocyte count and ESR did not have diagnostic significance, a combination of microbiological and serological tests showed a high diagnostic sensitivity and specificity. In contrast to the former GDR and to most European neighbours, the former Federal Republic overrated the side effects of active vaccination as compared to the various risks of natural infection. This resulted in a decline of vaccine acceptance to less than 10% in several areas of the former FRG. It is anticipated that the altered recommendation in favour of vaccination, and especially the future application of acellular vaccines with less side effects, will result in the elimination of whooping cough in all areas of Germany.
