RT Journal A1 Berman SJ T1 TReatment of malaria JF JAMA JO JAMA YR 1969 FD July 14 VO 209 IS 2 SP 269 OP 269 DO 10.1001/jama.1969.03160150055021 UL http://dx.doi.org/10.1001/jama.1969.03160150055021 AB To the Editor:—  Dr. Swisher's observations on the length of illness and the incidence of anemia in patients treated with chloroquine-pyrimethamine-sulfisoxazole (CPS) (208:695, 1969) are not surprising as patients transferred from the Naval Support Activity Hospital (where most of the CPS treatment program has been initiated) to the Sixth Convalescent Center are generally selected because of an expected lengthy convalescent period. From July through October 1968, approximately 950 cases of Plasmodium falciparum malaria were treated at NSA Hospital of which 95% received CPS. The patients seen by Dr. Swisher represent only 18% of this population. His comparison between forms of therapy may be invalid as the populations are potentially dissimilar.
