Objectives This study evaluated the effectiveness of rapid diagnostic testing (RDT) for the early detection of imported dengue cases at Gimhae International Airport in the Republic of Korea, and analyzed patient characteristics and response processes following positive results.
Methods From 2022 to 2024, 334 individuals underwent RDT at the airport. Testing was performed for travelers presenting with dengue-like symptoms or recent mosquito bites. Two dengue RDT kits (NS1 and immunoglobulin G/M) were used, and confirmatory tests—including real-time reverse transcription polymerase chain reaction and enzyme-linked immunosorbent assays—were performed for RDT-positive cases. Time intervals between sample collection and diagnostic confirmation were compared by institution type and day of the week.
Results Of the 334 cases tested, 12 yielded positive RDT results, and 3 were confirmed as dengue. No confirmed cases were identified among asymptomatic travelers or those with travel durations shorter than 5 days. All 3 confirmed cases showed moderate or higher RDT intensity. The confirmatory results were negative for all 7 marginally positive cases. The average turnaround time for diagnostic confirmation was 4.00 days in hospitals versus 2.71 days in public health centers. Samples collected on weekdays produced faster results (2.33 days) than those collected across weekends (5.00 days). One individual with a strong RDT-positive result declined confirmatory testing.
Conclusion RDT is a valuable tool for detecting dengue at ports of entry. However, timely confirmatory diagnosis requires improved inter-agency coordination and logistical systems, particularly for weekend operations. These findings offer practical insights for strengthening quarantine-based infectious disease control.
<p>The cataclysmic COVID-19 pandemic erupted silently causing colossal impact worldwide, the repercussions of which indicated a lackadaisical vigilance in preparation for such a pandemic. This review assessed the measures taken by nations to contain this pandemic. A literature review was conducted using Medline, Google Scholar, Science Direct, Scopus, and WHO website. There were 8 nations (selected from the GHS index list) appraised for containment strategies. This was achieved by using mortality rate (per million) as the primary endpoint. The nations which were proactive, initiated scientific strategies earlier with rigor, appeared to have succeeded in containing the pandemic, although it is still too early to arbitrate a verdict. The so called “pandemic war” mandates international, interdisciplinary, and interdepartmental collaboration. Furthermore, building trust and confidence between the government and the public, having transparent communication, information sharing, use of advanced research-technology, and plentiful resources are required in the fight against COVID-19.</p>

<p>South Korea is operating a flexible quarantine management system which is based on the results of epidemiological investigations of patients arriving from overseas with coronavirus disease-19 (COVID-19), and closely monitoring COVID-19 outbreaks. South Korea has designated countries with a localized, high prevalence of infection as “quarantine inspection required areas” and has reinforced quarantine measures by applying special immigration procedures for people entering South Korea. Furthermore, South Korea also provides information on international travel history of entrants (who are South Korean citizens and foreign nationals) to all medical institutions, through the smart quarantine information system. On March 11<sup>th</sup> 2020, the World Health Organization characterized COVID-19 as a pandemic. Inevitably, the number of patients from overseas with COVID-19 (based on 10,000 people entering South Korea), increased to 10 cases in the second week of March, 37 cases in the third week, and 67.7 cases in the fourth week. However, after enforcing quarantine strengthening measures, and with a decrease in the number of people entering the country, the number of cases decreased to 52.0 in the first week of April.</p>

<p>It was supposed to analyze status and affecting factors in water and food-borne communicable disease by screening entrants with diarrhea symptom at the point of entry in Korea</p></sec>
<sec>
<title>Methods</title>
<p>Symptomatic travelers with water and food-borne communicable diseases who entered Korea were diagnosed by a health declaration and detection of causative agents in water and food using laboratory tests. Among those entered in 2017, the affecting factors in the incidence of communicable diseases among those who had diarrhea at the entry into Korea, were analyzed, with frequency and chi-square test.</p></sec>
<sec>
<title>Results</title>
<p>The number of travel entrants with gastrointestinal communicable diseases increased by 40.19% from 2013 to 2017. The percentage of causative agents of water and food-borne communicable diseases was the highest at 69.2% from July to September. The rate of detection of causative agents of communicable disease pathogens in travelers from Southeast Asia entering Korea was 70.2%, which was higher than people arriving from East Asia and Central Asia (57.5%; <italic>p</italic> < 0.001).</p></sec>

<title>Conclusion</title>
<p>The positive ratio of causative agents of water and food-borne communicable diseases was high among travelers that had entered Korea from July to September, with a high number among entrants from Southeast Asia. Based on the positive detection of causative agents, the entry period and countries visited were statistically significant affecting factors (<italic>p</italic> < 0.001).</p></sec>
