While the notified crude incidence rates(per 100,000 persons, CIR) of new tuberculosis between 2016 and 2017 decreased in nationwide and 16 provinces, except Jeju Province, Korea. The aim of this study was to compare CIRs of Jeju Province and nationwide by calendar years and age groups in order to interpret the increasing trend of CIR in Jeju Province. The data source was the Integrated Diseases and Health Control System of the Korea Centers for Disease Control and Prevention. The selection criteria were the notified new cases as tuberculosis, who had the address as Jeju Province at diagnosis, between 2011 and 2018. The 95% confidence interval of CIR was estimated based on Poisson distribution. There was not statistically significant difference of CIRs between Nationwide and Jeju Province of 2011 and 2018, except 2016. Especially the CIR of group aged over 65 years in Jeju Province, 2016 was significantly lower compared to Nationwide CIR. But, the CIR of group aged 30~50 between 2017 and 2018 showed significantly higher compared to Nationwide CIR. Based on the results, the fact of increasing CIR from 2016 to 2017 in Jeju Province might be interpreted as an introduction of new tuberculosis screening project rather than real increased CIRs.

Objectives: Jeju Province in Korea reported 627 coronavirus disease 2019 (COVID-19) cases between January 20, 2020, and March 31, 2021. This study analyzed the sources of infection among confirmed cases in Jeju Province, a self-governed island. Methods: The sources of infection were broadly categorized as follows: (1) infections from overseas (confirmed patients who reported travel overseas or contact with overseas travelers); (2) infections from outside Jeju Province (confirmed patients who had visited other provinces or had contact with individuals who had traveled to other provinces in Korea); and (3) unknown sources of infection (confirmed patients who were infected following contact with an infected person whose source of infection was unknown). The chi-square test was used to analyze the differences in the distributions of related variables for each source of infection. Results: Of the 627 confirmed cases, 38 (6.1%) were infections from overseas sources, 199 (31.7%) were from outside of Jeju Province, and 390 (62.2%) were from unknown sources. Jeju Province had no cases with an unknown source of infection during the first and second waves of the nationwide outbreak. Conclusions: Infections from overseas sources could be blocked from spreading to local communities in Jeju Province by conducting screening at the airport, along with the preemptive suspension of visa-free entry. In addition, considering the scale of the nationwide outbreak, measures must be established to delay outbreaks from unknown sources of infection caused by sources outside Jeju Province.

Purpose: Classical swine fever (CSF) reemerged on CSF-free Jeju Island where vaccination is not practiced by the unintentional injection of a live attenuated vaccine (modified live attenuated vaccines-low-virulence Miyagi [MLV-LOM]) in 2014. Since the Jeju provincial authority is considering adopting a voluntary immunization policy using a CSF-E2 subunit vaccine to combat LOM-derived CSF endemic, this study aimed to evaluate in Jeju herds. Materials and Methods: Two vaccination trials using the Bayovac CSF-E2 vaccine licensed for use in South Korea assessed the safety and humoral immunity of the CSF-E2 vaccine in breeding (trial 1) and nursery animals (trial 2) under farm application conditions. Results: Neither local nor systemic (including reproductive) adverse effects were objectively observed in pregnant sows and young piglets following a respective vaccination regime at pregnancy or weaning, respectively. Trial 1 showed that sows immunized with the CSF-E2 vaccine possessed high and consistent E2-specific and neutralizing antibody levels. The CSF-E2 vaccine-immunized pregnant sows subsequently conferred appropriate and steady passive immunity to their offspring. In trial 2, a double immunization scheme of the CSF-E2 vaccine in piglets at 40 and 60 days of age could elicit a consistent and long-lasting adequate antibody response. Additionally, the two trials detected no E^rns-specific antibody responses, indicating that CSF-E2 vaccine can differentiate infected from vaccinated animals (DIVA). Conclusion: Our trial data collectively provide invaluable information on applying the CSF-E2 subunit vaccine to circumvent the possible drawbacks associated with the MLV-LOM concerning the safety, efficacy, and DIVA, in the LOM-endemic field farms and contribute to advanced CSF eradication on Jeju Island.

Jeju Province has unique geographical and climatologic characteristics compared with other areas in Korea. Thus it needs to evaluate the status of nationwide notifiable infectious diseases(NND) continuously. The aim was to conduct a descriptive study for NNDs in Jeju Province, 2001~2019. The source of data was on the Infectious Disease Statistics System operated by Centers for Diseases Control & Prevention in Korea between 1 September 2001 and 31 August 2019. When calculating the proportion of the sum of years showing a higher incidence in Jeju province than nationwide divided by the sum of comparing years, the NDD with the proportion of the sum of years over 75% in 2001~2019 included varicella and syphilis. The results support significant evidence to plan strategies and distribute community resources for the control and prevention of NND in Jeju Province, Korea.
