Update: Cold Injuries, Active and Reserve Components, U.S. Armed Forces, July 2017–June 2022.

From July 2021 through June 2022, a total of 482 members of the active (n=435) and reserve (n=47) components had at least 1 cold injury. The crude overall incidence rate of cold injury for all active component service members in 2021-2022 (33.1 per 100,000 person-years [p-yrs]) was slightly lower than the rate for the 2020-2021 cold season (35.5 per 100,000 p-yrs). In 2021-2022, frostbite was the most common type of cold injury among active component service members in all 4 services. Among active component members during the 2017-2022 cold seasons, overall rates of cold injuries were generally highest among male service members, non-Hispanic Black service members, the youngest (less than 20 years old), and those who were enlisted. The number of cold injuries associated with overseas deployments during the 2021-2022 cold season (n=13) was similar to the two previous cold seasons (10 in 2019-2020 and 11 in 2020-2021). Frostbite accounted for more than half (n=9) of the cold injuries identified in service members deployed outside of the U.S. during the 2021-2022 cold season.
