Malaria surveillance : 1963 annual summary
  • Description:
    During the calendar year 1963 there was a significant increase in reported cases of malaria in the United States* A total of 148 confirmed and presumptive cases of malaria with onsets of illness during 1963 were reported to Malaria Surveillance. This represents a 67% increase over the previous 7 year average since active case investigation was established (Table I). This increase is believed to be due partially to improved methods of reporting, but probably represents a real increase in the number of cases of malaria seen in this country.

    There was a two-fold increase in the number of civilian cases of malaria in 1963 as compared to the previous year (90 vs. 44). Fewer military cases of malaria were reported this year as compared to last year (58 vs. 75). Thirty-five cases of malaria occurring in merchant seamen were reported in 1963. Twelve of these cases represent a single outbreak of imported malaria which occurred aboard a merchant vessel calling at U.S, ports. A description of this epidemic appears in Section V.
