Malaria infection remains a potential health threat to U.S. service members located in or near endemic areas due to duty assignments, participation in contingency operations, or personal travel. In 2024, a total of 30 active and reserve component service members were diagnosed with or reported to have malaria, a 23.1% decrease from the 39 cases identified in 2023. Over half of U.S. service member malaria cases in 2024 were caused by Plasmodium falciparum (56.7%, n=17), followed by unspecified types of malaria (33.3%, n=10) and P. vivax (10.0%, n=3). Malaria cases were diagnosed or reported from 18 different medical facilities in the U.S., Germany, Africa, Japan, Middle East, and South Korea. Of the 27 cases with a known location of diagnosis, 11 (40.7%) were reported or diagnosed outside the U.S. This report documents a total of 30 malaria cases in 2024, a 23.1% decrease from 39 cases in 2023, mainly due to declines in Africa and other or unspecified locations. As in 2023, Plasmodium falciparum continues to constitute over half of new malaria cases (n=17, 56.7%) among active and reserve component U.S. service members.
由于任务分配、参与应急行动或个人旅行，疟疾感染对身处流行地区或其附近的美国军人来说，仍然是一个潜在的健康威胁。2024年，共有30名现役和预备役军人被诊断出患有疟疾或报告感染疟疾，比2023年确诊的39例减少了23.1%。2024年，超过一半的美国军人疟疾病例是由恶性疟原虫引起的（56.7%，n = 17），其次是未指明类型的疟疾（33.3%，n = 10）和间日疟原虫（10.0%，n = 3）。疟疾病例是在美国、德国、非洲、日本、中东和韩国的18个不同医疗设施中被诊断或报告的。在已知诊断地点的27例病例中，有11例（40.7%）是在美国境外被报告或诊断的。本报告记录了2024年总共30例疟疾病例，比2023年的39例减少了23.1%，主要原因是非洲以及其他或未指明地点的病例数下降。与2023年一样，恶性疟原虫在现役和预备役美国军人新感染的疟疾病例中继续占半数以上（n = 17，56.7%）。
