Background: The Field Epidemiology Training Program Frontline, initiated by the Korea Disease Control and Prevention Agency in 2019, aims to enhance the competencies of infectious disease practitioners across 17 regions in South Korea. With the September 2024 amendment to the Infectious Disease Prevention Act mandating infectious disease prevention and crisis response training for government employees who are associated with infectious diseases responses, there is an urgent need to assess and optimize the effectiveness and cost-efficiency of such competency-based education programs amidst constraints of budget and manpower. Methods: This study examined the educational needs and priorities of public health competencies among infectious disease practitioners. The competency framework for Infectious Disease Response Practitioners (IDRP) in South Korea was used to evaluate the validity, importance, and performance level of competencies for infectious disease response personnel. For the training needs analysis, differences in performance by group were analyzed, and an importance performance analysis (IPA) was conducted using the Borich Needs Assessment based on the IPA matrix to derive training priorities. Results: The analysis revealed a significant gap between perceived importance and selfreported performance levels in most competencies, especially epidemiologic methods.Competencies related to safety and ethics, fieldwork, and crisis management have high importance and performance ratings, indicating a need for ongoing training. Of the 27 competencies, the IPA identified specific training needs and priorities, suggesting eight competencies for focused intervention to strengthen the capacity of IDRPs. Conclusion The IDRP competency framework in South Korea plays a pivotal role in establishing a standardized, competency-based approach to training IDRP. The identified gaps and training priorities highlight the need for continued curriculum development and the integration of real-world, field-based scenarios into training programs.

Purpose: This study aimed to investigate the optimal withdrawal time (WT) for initial surveillance colonoscopy after curative resection for colorectal cancer (CRC) by comparing anterior/low anterior resection (AR/LAR) and right hemicolectomy (RHC) groups. Methods: This retrospective study analyzed 1,212 patients who underwent initial surveillance colonoscopy after CRC resection between 2015 and 2022. The patients were divided into the AR/LAR (n = 846) and RHC (n = 366) groups. The optimal WT was determined using receiver operating characteristic curve analysis and validated using logistic regression models. The adenoma and advanced neoplasia detection rates (ADR/ANDR) were evaluated based on the optimal WT. Results: The optimal WT was 7 and 6 minutes in the AR/LAR and RHC groups, respectively. In multivariate analysis, WT ≥7 and ≥6 minutes in the AR/LAR (odds ratio [OR], 2.38; 95% confidence interval [CI], 1.75–3.24; P < 0.001) and RHC (OR, 2.64;95% CI, 1.59–4.39; P = 0.001) groups, respectively, were significant factors for adenoma detection. In the AR/LAR group, ADR was 41.5% for WT ≥7 minutes compared to 21.9% for WT <7 minutes (P < 0.001). In the RHC group, ADR for WT ≥6 minutes was 33.9% compared to 15.8% for WT <6 minutes (P < 0.001). The ANDR also significantly improved with longer WTs in both groups. Conclusion This study suggests that a minimum WT of 7 and 6 minutes for AR/LAR and RHC patients, respectively, during the initial surveillance colonoscopy after CRC resection is optimal for maintaining a satisfactory ADR and ANDR. These findings highlight the importance of tailoring colonoscopic procedures according to the type of surgical resection.

The Korean Society of Infectious Diseases has been regularly developing guidelines for adult immunization since 2007. In 2023, the guidelines for the following seven vaccines were revised: influenza, herpes zoster, pneumococcal, tetanus-diphtheria-pertussis (Tdap), human papillomavirus (HPV), meningococcal, and rabies vaccines. For the influenza vaccine, a recommendation for enhanced vaccines for the elderly was added. For the herpes zoster vaccine, a recommendation for the recombinant zoster vaccine was added. For the pneumococcal vaccine, the current status of the 15-valent pneumococcal conjugate vaccine and 20-valent PCV was described. For the Tdap vaccine, the possibility of using Tdap instead of tetanus-diphtheria vaccine was described. For the HPV vaccine, the expansion of the eligible age for vaccination was described. For the meningococcal vaccine, a recommendation for the meningococcal B vaccine was added. For the rabies vaccine, the number of pre-exposure prophylaxis doses was changed. This manuscript documents the summary and rationale of the revisions for the seven vaccines. For the vaccines not mentioned in this manuscript, the recommendations in the 3rd edition of the Vaccinations for Adults textbook shall remain in effect.

Background: A healthcare system’s collapse due to a pandemic, such as the coronavirus disease 2019 (COVID-19), can expose healthcare workers (HCWs) to various mental health problems. This study aimed to investigate the impact of the COVID-19 pandemic on the depression and anxiety of HCWs. Methods: A nationwide questionnaire-based survey was conducted on HCWs who worked in healthcare facilities and public health centers in Korea in December 2020. Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) were used to measure depression and anxiety. To investigate factors associated with depression and anxiety, stepwise multiple logistic regression analysis was performed. Results: A total of 1,425 participating HCWs were included. The mean depression score (PHQ-9) of HCWs before and after COVID-19 increased from 2.37 to 5.39, and the mean anxiety score (GAD-7) increased from 1.41 to 3.41. The proportion of HCWs with moderate to severe depression (PHQ-9 ≥ 10) increased from 3.8% before COVID-19 to 19.5% after COVID-19, whereas that of HCWs with moderate to severe anxiety (GAD-7 ≥ 10) increased from 2.0% to 10.1%. In our study, insomnia, chronic fatigue symptoms and physical symptoms after COVID-19, anxiety score (GAD-7) after COVID-19, living alone, and exhaustion were positively correlated with depression. Furthermore, post-traumatic stress symptoms, stress score (Global Assessment of Recent Stress), depression score (PHQ-9) after COVID-19, and exhaustion were positively correlated with anxiety. Conclusion In Korea, during the COVID-19 pandemic, HCWs commonly suffered from mental health problems, including depression and anxiety. Regularly checking the physical and mental health problems of HCWs during the COVID-19 pandemic is crucial, and social support and strategy are needed to reduce the heavy workload and psychological distress of HCWs.

Canine distemper virus (CDV), canine adenovirus type 2 (CAV-2), canine parvovirus (CPV), and canine parainfluenza virus 5 (CPIV-5) are the major viral pathogens in dogs. Despite the availability of vaccines for dogs against these four viral pathogens, investigations of antibodies against these pathogens have rarely been reported in South Korea. In this study, we investigated the recent incidence of viral diseases in dogs and conducted sero-surveillance for CDV, CAV-2, CPV, and CPIV-5 in Korean dogs. The most frequently diagnosed canine viral disease in Korean dog samples from 2000 to 2022 was CPV infection, which accounted for 48.7% (464/953) of the cases. A total of 400 dog serum samples collected between 2019 and 2022 were screened for the presence of virus-neutralizing antibodies against CDV, CAV-2, CPV, and CPIV-5. The overall seropositivity rates for CDV, CAV-2, CPV, and CPIV-5 were 83.8%, 77.8%, 99.3%, and 82.0%, respectively. The protection rate against CPV was the highest (98.3%) and that against CAV-2 was the lowest (44.8%) in dog sera. Male and female dogs showed no significant differences in seropositivity rates. CDV and CPIV-5 seropositivity increased with age in dogs, and the highest incidence and seropositivity rates of CPV indicated that Korean dogs have been continuously exposed to wild CPV, and that CPV is a pathogen that urgently requires attention among canine viral diseases.

Objective: This study evaluated the clinical usefulness of mean platelet volume (MPV) for predicting functional outcomes in subarachnoid hemorrhage (SAH) patients. Methods: This is a retrospective analysis of patients who were diagnosed with SAH in the emergency room. Based on their modified Rankin Scale (mRS) score, patients were divided into two groups: 0-2 (good outcome) and 3-6 (poor outcome). Univariable and multivariable analyses were performed to investigate whether MPV, along with other multiple factors, was associated with poor prognosis. Receiver operating characteristic (ROC) curve analysis was performed to determine the value of MPV as a predicting factor of neurological prognosis. Compared to other factors, Hunt Hess grade (HHG) and modified Fisher grade (mFG) considerably influenced the outcomes in both groups (Model 1; model including all factors). Hence, a new model (Model 2) was constructed, comprising multiple factors excluding these two factors. Results: A total of 143 patients were included in this study. Although MPV was different between the two groups, it was not a significant factor in Model 1 in the multivariable analysis. In Model 2, MPV (odds ration [OR], 1.71; 95% confidence interval [CI], 1.05-2.8), age (OR, 1.06; 95% CI, 1.03-1.1), and surgical treatment (OR, 0.37; 95% CI, 0.15-0.87) were significant factors related to poor outcomes. Area under the curve (AUC) of Model 1 was 0.93, 0.85 in HHG; 0.78 in Model 2, 0.65 in mFG, and 0.62 in MPV. Conclusion Although MPV differed significantly between the good and poor outcome groups, it is insufficient to predict poor outcomes in SAH patients as an independent biomarker.
