Ji Yun Noh 교수의 연구실은 감염병 역학, 특히 인플루엔자 및 코로나19와 같은 급성 전염성 질환의 유행 패턴과 예방 전략을 중심으로 연구를 진행하고 있습니다. 사회적 거리두기, 마스크 착용 등 비약리적 간접 조치가 인플루엔자 유행에 미치는 영향을 분석하고, 병원 내 감염 예방 체계 및 혈액 투석 환자 등 취약군의 백신 반응성에 대한 연구도 수행하고 있습니다. 특히 혈청역학적 조사와 병원 기반 감시 체계를 통해 감염병의 실제 유통률과 집단면역 수준을 파악하는 데 초점을 맞추고 있습니다.

Social distancing has been adopted as one of basic protective measures against coronavirus disease 2019 (COVID-19). During 2019-2020 season, influenza epidemic period was exceptionally short and epidemic peak was low in comparison with previous seasons in Korea. Influenza epidemic pattern was bimodal in 2016-2017 and 2018-2019 seasons, however, influenza viruses have rarely been circulating in spring, 2020 in Korea. Although multiple factors could affect the size of influenza epidemic, extensive
Since it first emerged in December 2019, coronavirus disease 2019 (COVID-19) has spread rapidly worldwide. During the pandemic of an emerging infectious disease, it is very important to prevent nosocomial outbreaks and operate hospitals safely to maintain their functions. In this article, we present the strategies for safe hospital operations based on the experiences of the Republic of Korea early in the COVID-19 pandemic. Each hospital should maintain multiple layers of defenses to prevent even
Serosurveillance studies reveal the actual disease burden and herd immunity level in the population. In Seoul, Korea, a cross-sectional investigation showed 0.07% anti-severe acute respiratory syndrome coronavirus-2 antibody seropositivity among 1,500 outpatients of the university hospitals. Low seroprevalence reflects well-implemented social distancing. Serosurveillance should be repeated as the pandemic progresses.
The MF59-adjuvanted influenza vaccine showed better immunogenicity than the non-adjuvanted influenza vaccine in CKD patients undergoing HD.
This study is valuable as the first extensive laboratory surveillance of the epidemiology of respiratory viruses in ILI patients through a teaching hospital-based influenza surveillance system in South Korea.
In conclusion, most (>85%) patients carry NAb until 6 months after diagnosis of SARS-CoV-2 infection, providing insights for establishing vaccination strategies against COVID-19.
