RESUMO
A complex differentiated system of influenza control, based on scientific principles, was introduced into practice during 1976-1980 in Severodvinsk. The main component of this system was the mass prophylactic immunization of the population of the city, including children and elderly persons, with live and inactivated vaccines manufactured in the USSR. At the period of influenza epidemics remantadin was used for the urgent prophylaxis and treatment of influenza. As a result, influenza morbidity in Severodvinsk was reduced 1.5-2 times in comparison with that in the neighboring control cities. The cases of pneumonia and bronchitis, the most severe postinfluenza complications, decreased in number 1.8 and 1.4 times, respectively. The proportion of influenza A in the structure of acute respiratory diseases decreased by one-half. These results demonstrate the effectiveness of the prophylactic and therapeutic measures carried out in the city.
