RESUMO
A study was carried out on the influenza epidemic which broke out in the 21 804-inhabitant health area of the Cristóbal Larra Polyclinic of City of Havana Province on February 29, 1988. It was found that medical consultations for acute respiratory tract infections totalled 2046 during the 30-day epidemic; 1860 of these (90.9%) were first consultations, representing about 9% of the area population. The epidemic peak was reached 22 days after the outbreak. Higher consultation rates were of patients under 5 years, and the highest consultation coefficients were registered on Mondays. The application of the Rvachov-Baroyan model for local epidemic prognosis was not effective in the health area under study.

The present work presents the study of morbidity due to acute respiratory infections (ARI) in areas of the town of Lisa in Ciudad Habana, and Isla Juventud (Cuba), to characterize different aspects of morbidity measured by health care attendance and to measure true morbidity. About 90% of consultations for ARI were first-time consultations, while their ratio to further consultations was 5.3. True morbidity rates (TMR), obtained trough active research, ranged from 110.4 to 163.4 cases per 1000 inhabitants, considerably higher than morbidity rates measured by primary care consultations (MRPCC) in the same time period. The true morbidity index (TMI), as measured by the ratio of the two previous rates, ranged from 5 to 15. A high proportion (47.6%) of cases reported no medical care attendance. These results provide approximate estimates of true morbidity in the study area, and allow the establishment of a new control program, also improving epidemiologic surveillance within primary care activities.
