There are several processes and techniques of assessing the medical importance of a disease in a given country. However, such studies are sometimes very difficult to make because reliable statistics are not available. This is exactly the case of Brazil, where the evaluation of the measles problem can only be made in selected parts of the country by the utilization of mortality data.
Two areas were chosen for this study: the Municipality of São Paulo (population as of July 1, 1960: 3,888,710) and the State
MEASLES 1930 1940 1960 1930 1940 of Guanabara (population as of July 1, 1960: 3,288,296), representing together about 11% of the total population of the country. They include the 2 largest Brazilian urban centers, the cities of São Paulo and Rio de Janeiro, which have more than 50% of all practicing medical doctors of Brazil.
