摘要

In October 2016, we received reports of five deaths among prisoners with leg swelling of unknown etiology in southwestern Ethiopia. A descriptive cross-sectional study was conducted to investigate the outbreak. A suspected case was defined as a prisoner with leg swelling of unknown etiology noted between May 15, 2016 and November 29, 2016. A total of 118 suspected cases were identified with unilateral or bilateral leg swelling without an identifiable cause from a total of 2,790 prisoners. Eight of the suspected cases were thoroughly examined, and seven of these suspected cases had clinical findings consistent with scurvy. Three of the clinical cases had undetectable vitamin C levels in the serum. The attack rate for the prison was 4.2 (118/2,790), and 11 deaths were identified, making the case fatality rate 9.3 (11/118). Clinical cases of scurvy had symptoms of fatigue, myalgia, arthralgia, and signs of follicular hyperkeratosis, petechiae, peripheral edema, and oral lesions. All clinical cases had severe anemia with hemoglobin , 6.0 g/dL. The diet provided by the prison excluded fruits and vegetables. Scurvy was determined to be the cause of the outbreak, and vitamin C supplementation was promptly initiated. All symptomatic prisoners improved, and no further cases were identified in a 4-week follow-up period of active surveillance.
