  Objectives: Climate change and the expansion of international exchanges have significant impacts on ecosystems and human society. Among these, an increase in mosquito habitats promotes the possibility of introducing infectious diseases and mosquitoes overseas. The surveillance of invasive mosquitoes is an essential intervention in the prevention of such factors.
  Methods: The Korea Disease Control and Prevention Agency selected 36 sites from 19 domestic airports and seaports for surveillance twice a month from April to October 2024 to prevent the introduction and spread of mosquito-borne diseases. BG-sentinel traps, light-emitting diode traps, and gravid traps were used for mosquito collection, and mosquitoes were identified and tested for the presence of flaviviruses (i.e., dengue, yellow fever, West Nile, Japanese encephalitis, and Zika virus).
  Results: The collection of 47,879 mosquitoes from 15 species included major species, such as Aedes albopictus, Aedes vexans, and Culex pipiens. Among these, Culex pipiens, the vector for West Nile fever, accounted for 52.4%, followed by Aedes vexans (17.5%) and Aedes albopictus, which transmits Dengue fever and Zika virus infection (7.3%). Non-native species, such as Aedes aegypti and Haemagogus spp., were not observed. Flaviviruses were not detected in the mosquitoes.
  Conclusions: The National Quarantine Stations and public health centers were notified of the surveillance results to ensure effective disinfection and mosquito control. The study findings can contribute significantly to the establishment of a comprehensive system to prevent the introduction of invasive mosquitoes and vector-borne diseases within quarantine areas through cooperation with relevant authorities.

  Objectives: Tuberculosis (TB) is a common infectious respiratory disease requiring long-term treatment, which increases the risk of treatment discontinuation. State institutional intervention is thus inevitable. We reviewed the background, history and current implementation status of hospitalization orders for patients with TB in the Republic of Korea.
  Methods: We analyzed historical legislation and regulations within The Tuberculosis Prevention Act, national TB control plans, and management guidelines. Additionally, we reviewed data on hospitalization orders from the Korea Tuberculosis Surveillance System (KTB-Surv) and collected by the Korea Tuberculosis Network (KTB-Net).
  Results: Hospitalization orders were issued for approximately 1% (0.7–1.4%) of annual TB cases from 2011 to 2023. Multidrug-resistant-TB was the dominant diagnosis associated with such orders in the early years (2012–2015) of the program. After 2016, following the full waiver of out-of-pocket medical expenses for TB treatment, the proportion of cases classified as “other diagnoses” (including severely vulnerable and elderly patients) increased significantly from 1.6% to 36.8%.
  Conclusions: The hospitalization order system plays a critical role in improving treatment compliance and prevent TB transmission within communities. It also provides active support for medical and living expenses during inpatient isolation. Strategic reforms are needed to ensure the system adapts to future challenges, including those precipitated by population aging and changing family structures.
