* A case was defined as symptomatic or asymptomatic illness that occurs in the United States or one of its territories in a person who has laboratory-confirmed malaria parasitemia (microscopy or polymerase chain reaction), regardless of whether the person had previous attacks of malaria while in other countries. A subsequent attack of malaria occurring in a person is counted as an additional case if the demonstrated Plasmodium species differs from the initially identified species or if it is indicated as a relapsing infection demonstrating the same Plasmodium species as identified previously. If a subsequent attack of malaria occurs as a result of a drug-resistance failure then the case is not counted as an additional case.
† The number of cases reported for 2013 is different from that published in “Malaria Surveillance — United States, 2013.” This is because of delayed reporting of cases with symptom onset in late 2013 but counted as 2014 cases according to NNDSS definitions. This analysis reclassified all cases according to date of symptom onset.
