The digital response is an excellent infection prevention and control measure to minimize person-to-person contact when a respiratory infectious disease is rapidly spreading. However, few studies have explored the reasons for the development and utilization of these technologies. Here, we analyze documents by the Korean government, existing research, and news articles to provide a qualitative review of the digital response, and new concepts explored by Korea during coronavirus disease 2019, to apply them for the next infectious disease outbreak.

Effect of environmental factors and host on the growth and outbreak of various ginseng diseases was reviewed Environmental lectors included hydrogen ion concentration, moisture content, temperature, nutrition, and microbiol populations. Age of the ginseng plants in relation to several ginseng disease occurrence was also included in order to formulate the effective control measure for ginseng diseases. Damping-off caused by Rhizoctonia, Pythium, and Phytophthora, greymold by Botrytis, sclerotinia by Scleretinia, and phytophthora blight caused by Phytophthora were usually prevalent during the early growing season of ginseng when temperature is below 20$^{\circ}C$, while anthrac se caused by Colletotrichum, alternaria blight by Alternaria, and bacterial soft rot by Erwinia were so during the latter growing season when temperature is above 25$^{\circ}C$. However, the root rot incited by Fnarium and Cylindrocarpon caused severe damages throughout the growing season. Growth range of the temperature for a pathogen was highly related to the corresponding disease outbreak. Hydrogen ion concentration was highly related to the outbreak of sclerotinia, root rot, and red rot. Most severe outbreak of those diseases where the soil acidity was pH 4.7, pH 6.5- 7.5, and pH6.0-6.5, respectively. Nitrogen content in the soil was also related to outbreak of root rot and red rot. More red rot occurred where NH,-nitrogen is above 30 ppm and more root rot obtained when excessive nitrogen fertilizer applied. Yellow necrosis apparently was related to magnesium especially its ratio with potassium or calcium content in a soil. Fusarium Population showed significant .relations to missing rate of ginseng Plants in a Implanting ginseng field, while that of total bacteria showed similar relations in all ginseng field, However, in six year old ginseng fields, the more the Streptomyces population was, the less the Fusarium obtained. Consequently, less missing rate observed in a field where Streptomyces population was high. Damping-off, root rot, Rhytophthor a blight were mose severe on the nursery and on 2-3 years old ginseng plants, whereas sclerotinia, and grey cod, alteraria blight, anthracnose were severe on 4-6 years old ginseng plants. Root rot caused by Fusarium and Erwinia, however, was also severe regardless of the age of the plants when the roots were injured. Therefore, for the effective control of ginseng root rot most careful control of the disease during the early year should be rendered.

구제역은 전염성이 높고 치명적 결과를 유발하는 우제류 전염병이며, 2010/2011년도에 국내에서 발생한 구제역 (2010/2011 구제역)은 사회 및 경제적으로 국가에 재난 수준의 손실을 끼쳤다. 따라서 국가적 차원에서 구제역의 예방과, 발병 시 피해를 줄이려는 많은 노력을 하고 있다. 이러한 노력의 하나로 구제역의 전염 현상을 확률적으로 모형화하고 이해하려는 노력이 필요하다. 영국에서 발생한 2001년 구제역은 그 규모와 피해가 막대하여, 영국에서는 다양한 확률적 모형으로 구제역 전파 현상에 대한 이해를 통하여 미래의 발생에 대비하려는 연구가 이루어져 왔다. 그러나 2010/2011 구제역에 대하여는 확률적 모형을 활용한 연구가 미미한 편이다. 따라서 본 연구에서는 2010/2011 구제역에 대하여 시간-공간 확률 SIR 확률모형을 가정하고 시간과 공간에 따르는 전파 현상에 대하여 고찰한다. 농림수산검역검사본부에서 발표한 구제역 감염데이터와 통계청의 전국농가센서스 자료의 일부인 전체 우제류 농가의 데이터가 본 연구의 분석에 필요한 정도로 상세하지 않으므로 추정 및 보정작업을 통하여 데이터를 보완하였다. 감염데이터를 이용하여 커널함수를 추정하고, 전국 우제류 농장데이터를 이용하여 시뮬레이션을 통하여 모형의 모수를 추정하였다.

An outbreak of Staphylococcus aureus infections occurred in a university with an enrollment of 80 students in the city of Daejon, Republic of Korea. All nine S. aureus isolates from patients (n = 7), staff members (n = 1), and the fried chicken served as the lunch (n = 1) harbored the enterotoxin A gene and showed an identical antibioticresistant profile, PFGE banding pattern (STAS16.001), and sequence type, ST 6. These results suggested that the outbreak was associated with eating the fried chicken that had been handled by an infected staff member. This case report demonstrated a practical approach to identifying the source and transmission of an infection.

Objective: The outbreak of Middle East Respiratory Syndrome (MERS) started in South Korea in May 2015 and the end of crisis was declared in December 2015 by Korea Centers of Disease Control and Prevention (KCDC). However, Zika virus emerged in less than 2 months following MERS and showed higher mortality than other countries. This study is to assess the current prevention system of overseas infectious diseases, based on MERS and Zika virus outbreak and to suggest effective response system for the future. Methods: We conducted two surveys on medical specialists working at tertiary general hospitals regarding the effectiveness of responding system by KCDC against MERS and Zika virus and education in individual medical institutions using 5-Likert points. Response system was examined in three different periods as initial period, spreading period, and post disease period. Results: Although medical specialists received the notifications in initial period, no practical prevention was proven to be placed in responding stage by medical facilities (averagely 3.5/5 points in total and sub-analyses). During spreading period, there were several academic seminars conducted, which were evaluated as helpful. In post disease period, all answered that there were changes on patient treatment in all medical facilities, with mainly report system and the treatment regulations in case of suspicious patients for infection. Only 49% respondents answered positive on the possibility of initial responses. For questionnaire items regarding Zika virus, all answered that there were notifications prior to the first outbreak of the infected patient. Eighty% of respondents were aware of 'the Guideline system for traveling to dangerous areas', and answered that the system was moderately effective (averagely 3.8/5 points in total). For the effectiveness of prevention measures for foreign novel disease by KCDC, the average point was 3.0 in both of total and sub-analyses. Conclusion: There is not enough response system to prevent infectious disease in medical institutional and governmental levels in Korea. It would warrant the modification of overall medical system to improve preventive measures for initial spread of such diseases.

Pullorum disease caused by Salmonella pullorum, has been considered as one of the most important diseases in both clinically and economically in poultry industry since it had been firstly reported in 1925 in Korea. This disease is still problem in the industry in this country even though several attempts have been made to eradicate the disease. As one of the trials to solve the problem, we investigated the pattern of the outbreak of the disease, isolated the causative agent, S pullorum and tested biochemical properties, antimicrobial susceptibility and plasmid profiles of the isolates. Outbreak of the disease based on the species was the highest in layer followed by in Korean native chick, and broiler. Daily mean mortality in vertical transmission (0.90%) was higher than that in horizontal (0.14%). There was no seasonal difference in the outbreak. Also, biochemical properties and antimicrobial susceptibility pattern of the isolates were same. However four different plasmid profiles of the isolates were observed. These results suggested that S pullorum isolates were different in the genotype while they were same in phenotypes.

Pathogenic microbial foodborne disease outbreaks (PMFBDOs) have increased in many countries, the boom in food service establishment is not matched by effective food safety and control. In this study, we investigated the current state and the epidemic aspects of FBDOs in Korea and Japan. In Korea, the average prevalence rate of foodborne disease (FBD) was 15.0 per 100,000 population and cases per outbreak of FBD was 57.0. During the same period in Japan, the prevalence rate showed an average of 24.9, and the cases per outbreak were 16. When both prevalence rate and cases per outbreak were compared, the prevalence rate in Japan was much higher than that in Korea (p<0.01). However, average cases per outbreak of FBD in Japan were much lower than those in Korea (p<0.01). In Korea, outbreaks of FBDs were more common in spring (p<0.01), while in Japan, more frequent in summer and winter (p<0.01). Outbreaks of FBD occurred largely through restaurant and school foods (32.0% and 27.5%) in Korea. In Japan, the proportion of the outbreak cases in the restaurant and home were 23.7% and 12.1%, and cases of unknown causes of FBDs were 48.2%, respectively. Bacteria were the major causes of infection in both countries. The prevalence of PMFBDOs by Salmonella spp. Vibrio parahemolyticus and Staphylococcus aureus were much higher in Korea, while those by Camphylobacter spp. and SRSV were more common in Japan. The causes by virus were more frequent in Japan (13.7%) than in Korea (7.7%). The prevalence of FBDs in Korea and Japan showed characteristic differences, especially in the PMFBDOs due to such factors as geography, climate, culture, diet and food management.

About 4,500 mass burial sites of carcasses from the 2010/2011 outbreak of Foot-and-Mouth (FMD) disease in Korea show very slow stabilization speed, although more than 3 years have passed. Therefore, a plan is being considered to boost the speed of stabilization or removal. This is a study on the social value of the removal plan for 4,500 mass burial sites from the 2010/2011 outbreak of FMD in Korea. This valuation is based on the survey of 1,000 people living all over Korea. Korean people have a willingness to pay 101.2 billion Korean Won (about US $100 million). This value is a large amount, but it is small compared to the cost of a FMD outbreak. The cost for the Korean government from 5 outbreaks since 2000 ranged from 28.8 billion Won to 3.2 trillion Won. These were the costs only paid by the Korean government. One estimate reported that there would be a total damage of 1.4 trillion Won, if FMD outbreak occurs in Jeju Islands, a small part of Korea. If burial sites have very slow stabilization speed and some hazardous contents, the social damage will exceed the removal cost.

The recent Middle East respiratory syndrome coronavirus (MERS-CoV) outbreak has originated from a failure in the national quarantine system in the Republic of Korea as most basic role of protecting the safety and lives of its citizens. Furthermore, a number of the Korean healthcare system's weaknesses seem to have been completely exposed. The MERS-CoV outbreak can be considered a typical public health crisis in that the public was not only greatly terrorized by the actual fear of the disease, but also experienced a great impact to their daily lives, all in a short period of time. Preparedness for and an appropriate response to a public health crisis require comprehensive systematic public healthcare measures to address risks comprehensively with an all-hazards approach. Consequently, discussion regarding establishment of post-MERS-CoV improvement measures must focus on the total reform of the national quarantine system and strengthening of the public health infrastructure. In addition, the Korea Centers for Disease Control and Prevention must implement specific strategies of action including taking on the role of "control tower" in a public health emergency, training of Field Epidemic Intelligence Service officers, establishment of collaborative governance between central and local governments for infection prevention and control, strengthening the roles and capabilities of community-based public hospitals, and development of nationwide crisis communication methods.

Foot and mouth disease (FMD) is a highly contagions disease of cloven-hoofed animals and occurs in many non-European countries, in particular in huge parts of Asia including Turkey, in most countries of Africa and in parts of South America. The extreme contagiousness of the disease requires comprehensive to control an outbreak, causing high economic losses. The outbreak of FMD, which affects livestock including cattle, swine,sheep,goats,deer and other animals as a highly communicable disease that affects. The agency issued a statement noting that FMD disease does not spread to humans. The disease and meat from infected animals are news reports that more than 3.400.000 livestock have been ordered slaughtered so far across the country.
