ABSTRACT
Background@#This study aimed to identify the incidence rate of post-coronavirus disease-2019 (COVID-19) conditions in the Republic of Korea (ROK) Army and to investigate the trend of the incidence rate according to changes in dominant variants. @*Methods@#We used the results of a 19-item, self-completed survey of those who had recovered from COVID-19 in the ROK Army between March 24, 2020, and April 30, 2022. We used both descriptive and multiple logistic regression analyses to identify factors associated with the incidence rate of post-COVID-19 conditions. @*Results@#Among the total of 48,623 COVID-19 episodes in the ROK Army, the overall incidence rate of post-COVID-19 conditions was 32.9%. Based on the survey, the incidence of cough was the highest at 15.4%, followed by fatigue (15.1%) and sputum (13.8%). The delta variant had the highest incidence rate of post-COVID-19 conditions at 50.7%, whereas the omicron variant had the lowest at 19.7%. Concerning the type of post-COVID-19 condition, the neuropsychiatric symptoms had the highest incidence at 27.4% when the delta variant was dominant, and the respiratory symptoms were highest at 37.3% when the omicron variant was dominant. In the case of smell and taste symptoms, the incidence rate was high at 21.1% only when the delta variant was predominant. @*Conclusion@#The overall incidence rate of post-COVID-19 conditions in the ROK Army was 32.9%. When the delta variant was dominant, the overall incidence as well as the proportion of neuropsychiatric symptoms were high. However, as the omicron variant became dominant, the overall incidence decreased, but the proportion of respiratory symptoms increased.
ABSTRACT
This study was conducted to clarify the prevalence of common skin diseases and their associated factors among military personnel in Korea. Four dermatologists visited adjacent military units and examined soldiers. A structured questionnaire that included questions about known skin diseases, demographic information, and questions for the Perceived Stress Index was completed for each participant. The soldiers that had been diagnosed with a skin disease answered one additional questionnaire (Skindex-29) which assess the influence of an individual's skin disease on daily life. Of 1,321 soldiers examined, 798 (60.4%) had one or more skin diseases. The three most common skin problems were acne (35.6%), tinea pedis (15.2%) and atopic dermatitis (5.1%). The diseases closely related to the period of military service were acne, tinea pedis, viral warts and corns. The diseases related to the amount of stress were atopic dermatitis, seborrheic dermatitis, and acne. The most troublesome skin diseases were atopic dermatitis, tinea cruris, and seborrheic dermatitis. These results demonstrated that the prevalence of skin disease among military personnel in Korea is very high, and that some of the skin disorders may have a significant influence on their daily lives.
