Abstract

The introduction and rapid spread of chikungunya virus (CHIKV) into the Western Hemisphere after December 2013 pose a potentially significant risk to Department of Defense (DoD) personnel, operations, and the military healthcare system. This report describes the DoD experience with CHIKV between January 2014 and February 2015 using case reports in the Defense Medical Surveillance System's (DMSS) Reportable Medical Events database and the Navy and Marine Corps Public Health Center's laboratory test results database. Case finding identified 157 confirmed cases; of these, 118 (75.2%) were either active or reserve component service members and 39 (24.8%) were other beneficiaries. Exposure locations were known for 117 (74.5%) of all cases, and of these, 113 (96.6%) reported likely exposures in the Western Hemisphere; 85 (75.2%) of those cases occurred in Puerto Rico. Although historical data on CHIKV in DoD populations are scant, introduction of CHIKV into the Western Hemisphere with ongoing transmission appears to have resulted in a significant increase in the number of cases among DoD healthcare beneficiary populations.
