Despite the development of modern medical sciences, the outbreak and spread of infections continue to threaten populations, and the spread of infections among populations is caused by social contacts. There have only been a few studies on social contacts in the Republic of Korea (hereafter Korea). This study identified the types of social contacts in other countries through a systemic literature review and this helped provide basic data for Korea. Twelve studies were finally selected and then published from 2000 to December 2017. The most common study method was a retrospective contact diary (7cases, 58.3%), and random sampling (9cases, 75%). The number of contacts was 4.9-17.7/day, there were more frequent contacts during the weekdays than on weekends, and the most contacted people were those people that met daily. Physical contact was frequent at home. The highest frequency of contacts was between people 5-19 years old. In case of an epidemic, the spread of infection by this age group could be a concern. Assortative mixing was high in the 5-20 years old group, suggesting that this age group may be more likely to spread infection by contact within the same age group. Therefore, a national-wide survey on social contacts will be needed to predict the spread of infections, and to develop infection prevention based on a domestic basis in Korea.

Purpose: The purpose of this study is to investigate secondary infections within the households of newly diagnosed tuberculosis patients. Methods: We collected data on household infections of tuberculosis patients by retrospective review of medical records and telephone surveys. Results: Out of 321 newly diagnosed tuberculosis cases, a total of 253 patients who received telephone surveys were enrolled in this study. Less than 50% of the patients had household contacts screened for tuberculosis infection, and most of the patients were not aware of the necessity of testing. Out of 562 household contacts, there were 8 cases of secondary tuberculosis (1.4%, 8/562) in 7 households. There were 15 cases of latent infection (2.7%, 15/562) in 13 households. Out of 110 child and adolescent household contacts, there were no cases of secondary tuberculosis, and there were 8 cases of latent infection (7.3%) in 7 households, which was 20.5% among child and adolescent contacts screened for tuberculosis infection. In 3 of the cases (13.0%) that had secondary tuberculosis or latent infection in their households, the source of infection was extrapulmonary tuberculosis. There was no correlation between the frequency of household infections and the presence of pulmonary cavities, sputum AFB smear results, and microbiologically confirmed results. Conclusions: For effective investigation of tuberculosis contacts, it is necessary to raise general awareness on the necessity of investigating household contacts, and there should also be a continued assessment on tuberculosis contact investigation since government-supported programs.

HIV는 주로 성접촉을 통해 전염된다는 사실을 대부분 알고 있지만 막상 가족 중 한 사람이 HIV에 감염되었다고 했을 때 어떻게 해야 하는지 당황하는 경우가 많다. 일상적인 접촉으로는 전염되지 않는다는 피상적인 정보는 알고 있지만 국을 같이 떠먹고 세탁물을 함께 넣고 빨아도 되는지, 감염된 가족의 식기는 항상 소독을 해두어야 하는지 모든 것이 궁금할 것이다.

Since COVID-19 (Severe acute respiratory syndrome coronavirus type 2, SARS-Cov-2) was first discovered at the end of 2019, it has spread rapidly around the world. This study introduces an agent-based simulation model representing COVID-19 spread in South Korea to investigate the effect of detect level (contact tracing) on the virus spread. To develop the model, related data are aggregated and probability distributions are inferred based on the data. The entire process of infection, quarantine, recovery, and death is schematically described and the interaction of people is modeled based on the traffic data. A composite logistic functions are utilized to represent the compliance of people to the government move control such as social distancing. To demonstrate to effect of detect level on the virus spread, detect level is changed from 0% to 100%. The results indicate active contact tracing inhibits the virus spread and the inhibitory effect increases geometrically as the detect level increases.

Purpose: In order to prevent tuberculosis transmission early, it is important to diagnose and treat tuberculosis infection by investigating people who have contact with patients with active tuberculosis. Methods: From July 2014 to June 2017, the intrafamilial childhood contacts of the patients who were diagnosed with active tuberculosis at Chungnam National University Hospital were investigated for the presence of tuberculosis infection. We also retrospectively analyzed the treatment status of children treated with latent tuberculosis infection (LTBI) during the same period. Results: Among the 269 children who had intrafamilial contact with active tuberculosis patient, 20 (7.4%) did not receive any screening. At the first screening, one (0.4%) was diagnosed with pulmonary tuberculosis, seven (2.8%) had a previous history of tuberculosis infection, and 42 patients (16.9%) were diagnosed with LTBI. At the second screening, 29 patients (11.6%) were diagnosed with LTBI, and 61 patients did not finish the investigation. Only 188 (69.9%) out of 269 patients completed the investigation. Ninety patients received treatment for LTBI and 83 patients (92.2%) completed the treatment, of which 18 patients had side effects such as rash, fatigue, and gastrointestinal symptoms. However, there were no serious side effects requiring treatment discontinuation. Conclusions: The completion rate of childhood tuberculosis contact investigation was low, but the completion rate of LTBI treatment was high in children without serious side effects. In order to prevent and manage the spread of tuberculosis, active private-public partnership efforts and education of the patient and guardian are needed.

질병관리본부 발표자료에 따르면 우리나라의 2004년 3월 현재, 에이즈 감염인은 2,679명에 이른다. 이중 남자가 2,406명으로 $89.8\%$를 차지하고 있으며, 여자는 273명으로 $10.2\%$를 차지하고 있다. 통계에서 보듯이, 남성 감염인수는 여성 감염인수의 8.8배나 많고 감염인 연령의 $62.2\%$는 $20\~30$대에 분포되어 있다. 감염경로의 $97.7\%$는 성접촉으로 인한 감염이다. 그러나 감염이 확인되지 않은 실제 감염인 수는 보편적으로 확인된 숫자의$5\~10$배까지 추정되고 있으며, 아직까지 검사를 받아보지 않은 감염예상자가 상당히 많을 것으로 추측된다.

혈액등 체액이 접촉되는 성 활동과 수혈등 혈액 오염으로 감염되므로 이를 피하여야 한다. 감염가능성이 있는 대상자와의 성생활을 피해야 하며 부득이한 경우 콘돔의 사용이 요구된다.
