The number of malaria cases reported in the United States in 1968 was slightly less than the 1967 total (2,610 in 1968 vs. 2,855 in 1967). Vietnam returnees continued to account for over 90 percent of the cases. P. vivax accounted for 81 percent of the infections and falciparum 13 percent. Twelve cases were acquired in the United States. Five of these, all due to P. vivax were introduced cases, and seven, 3 due to P. falciparum, 3 due to P. malariae, and 1 due to J?. vivax, were induced cases. Four of the introduced cases occurred in civilians and were epidemiologically related. There were 6 malaria fatalities, all £. falciparum infections. Two of these cases occurred in seamen, 2 in Vietnam returnees, 1 in an American tourist, and 1 in the recipient of a blood transfusion.
