[Malaria. Analysis of 149 cases (1981-1987)].

: The epidemiological features of the 149 cases of malaria reported to the Institut Municipal de la Salut in Barcelona from 1981 to 1987 are reported. The yearly evolution of the number of cases showed a tendency to increase predominating in the summer months. The incidence rate for 1977 was 1.99/100,000. The districts with the highest rate of involvement were districts I (Ciutat Vella), owing to the immigration, and V (Sarria-Sant Gervasi), probably owing to overseas visitors. There was a remarkable predominance of males (63.8%), patients aged 20-40 years, and cases of African origin (81.81%); 50.42% of these came from Equatorial Guinea. The most commonly isolated plasmodium was P. falciparum (52.53%), with a progressive increase throughout the years. Only 13.43% of patients had followed a correct chemoprophylaxis. Malaria is still the most important protozoan infection in the world. In the present study its possible reintroduction in Spain is discussed. The malarial endemic used to be very important in this country, and its eradication was not achieved until 1964.
