IN a recent paper ( Bol. Of. San. Panamericana, 21, 233 ; 1942 ) Dr. Hugo J. D'Amato, secretary of the National Department of Hygiene at Buenos Aires, states that during 1940, and especially from January until April, there was a decided increase in the number of cases of malaria in North Argentina, where the disease is endemic, with the exception of those areas protected by the public health services, thus proving the efficiency of the methods applied. More than 170,000 patients were examined by the services of the National Department of Health and more than 20,000 in the provincial and municipal institutions ; this is an increase of 5 percent on the figures of the previous year. P. falciparum accounted for 33 percent of the infections as compared with 12 percent for the previous year. In 1940, 11,200 more patients were treated than in 1939 and more dispensaries were opened. About 1,600 kgm. of quinine are distributed every year, health education is carried out intensively, nearly 350,000 pesos are set aside yearly for preventive work, and private donations add 50,000. In 1940, 30,250 houses were visited, in 8,210 of which mosquitoes were found, chiefly Anopheles pseudopunctipennis and also a few A. arsimaculatus, A. cegyritarsis, A. perizi and A. albitarsis. Drainage, filling in, and other sanitary procedures were carried out on a large scale. More than 200,000 litres of petroleum and 70,000 kilos of Paris green were used.
