Purpose: This study was a within subject repeated pretest-posttest design done to compare the effect of disinfection and the degree of MRSA(Methicillin- resistant staphylococcus aureus) isolation from hand disinfectant in ICU nurses. Method: Out of the total internal medicine/surgery ICU nurses at a university hospital in Seoul, 29 female nurses who were participating in direct patient care were participants in this study. After collection of samples, Staphylococcus aureus and MRSA were isolated from the palms, nails and nasal cavities of the nurses according to disinfectants (soap and beta-scrub). Results: The effect of disinfection was greater in the beta-scrub group than in the soap group, and the effect of disinfection on palms was higher in the beta-scrub group than in the soap group. As for the degree of MRSA isolation, there was more isolation in palms in the soap group than in the beta-scrub group but there was no difference in the degree of MRSA isolation from the hand disinfectant in nails and nasal cavities. Conclusion: Beta-scrub showed a superior prolonged effect against transient bacteria compared with soap. Further, to reduce MRSA infection, we recommend interventions focused on these aspects.

An equine herpesvirus-4 (EHV-4) was isolated in nasal swabs collected in a horse showing respiratory clinical signs. Equine dermis cells inoculated with the sample were observed with characteristic viral cytopathic effects after 3 days of postinoculation and the infected cells exhibited bright intracelluar fluorescence by indirect immunofluorescence assay. At the nucleotide level, the partial glycoprotein B gene of the Korean EHV-4 isolate (K001) had 99.9% identity to 1942 strain (GenBank No. M26171). To author's knowledge, the report describes the first isolation and partial characterization of EHV-4 in Korea. The virus can be used for further study of EHV-4.

Purpose: The 2015 Middle East Respiratory Syndrome (MERS) outbreak and the recent COVID-19 pandemic have highlighted the lack of negative pressure isolation rooms and the fragility of the healthcare system. The need for healthcare facility transformation for respiratory infectious diseases has become more prominent due to COVID-19, and the purpose of this study is to provide a foundation for the rapid, economical, and safe construction of negative pressure isolation wards. Methods: This study analyzes the current status of hospitals that have been converted to negative pressure isolation rooms, and provides architectural plans and examples to provide a reference for bedroom change. Research data of this study have been obtained by analyzing the drawings of negative pressure isolation wards of nationally designated inpatient treatment beds and urgent isolation beds. In addition, the relevant literature of urgent isolation beds has been analyzed to derive bedroom change type. Result: In this study, a total of 21 isolation bed conversion methods have been presented. Implications: In order to change efficiently from a general ward to an isolation ward, it is necessary to consider the actual hospital's infectious disease transmission patterns and facility conditions.

Purpose: In this study influenza A (H1N1) infection control performance and stress in nurses were surveyed, to identify factors influencing stress for the nurses, and to provide basic materials for promoting infectious disease control by nurses. Method: The participants were 447 nurses who had worked at isolation clinics and/or isolation rooms in hub hospitals in the Honam region during the period of the outbreak of 2009 pandemic influenza A (H1N1) virus. Data were collected in February 2010 using self-report questionnaires. Results: The performance of participants from clinics was high for 'helping patients wearing masks', but low for 'maintaining distance over 1 meter among waiting patients'. The performance of participants from hospital rooms was high for 'putting a surgical mask on a patient going out of the room', but low for 'keeping patients' family out of the room'. The participants' stress was higher in those younger and less experienced nurses, those working at a hospital with 500-999 beds, those working at both isolation clinics and rooms, and those working at a clinic longer. Conclusion: In order to lower nurses' stress from working at isolation clinics/rooms for infectious diseases, we may need to deploy experienced nurses and limit their working days to five or less.

The purpose of this study is to compare and analyze the air infections in middle and small hospitals with the facilities of large national hospitals that have air-borne infection isolation (AII) wards through actual condition investigation and airflow analysis simulation (CFD) and to provide basic data for prevention. The method and scope of the study are as follows. First, through literature review, data related to prevention of infection spread in domestic medical institutions were investigated. Second, we conducted a survey on the status of isolation facilities to prevent the spread of infectious diseases in large hospitals and small and medium - sized clinics in Korea. Third, airflow analysis simulation (CFD) was carried out using the isolation ward of the nationally designated inpatient ward and the data of the plane and facility system of the small clinic. As a result of the study, it is found that regulations applicable to small and medium-sized clinics are insufficient. In addition, the simulation results show that the infectious disease virus is likely to spread to other patients in the hospital.

Purpose: The purpose of the study was to understand how patients experience everyday life in an isolation unit for hematopoietic stem cell transplantation (HSCT). Method: The data were collected from 25 patients with HSCT at the isolation unit from January to March in 2008 in one general hospital in Korea. The data were collected by participant observations and ethnographic interviews and were analyzed using ethnographic method. Results: Four themes regarding environmental area emerged: 'barrier pulling up the drawbridge', 'very strange world', 'small and restricted space tied by IV and other treatment lines', and 'loud noise in a silent space.' Three themes regarding patients emerged: 'facing fear and anxiety', 'continuation of loneliness and lethargy', and 'compromising with a very long, dull, and boring time'. These themes describe how patients with HSCT suffer from continuous physical and psychosocial problems in a confined space, while endeavoring to control these problems and to search for hope for a new life. Conclusion: The results of the study provide an in-depth understanding of the experience and culture of patients in an isolation unit for HSCT. They would be used in developing practical programs to decrease patient's culture shock including fear and anxiety at isolation unit for HSCT.

A total of 3,879 cases of feces and rectal swab from patient was collected in H. hospital from January 1974 to December 1986 in Seoul. Among the materials, the number of cases of Shigella spp. isolated were 197 strains of 139 patients. Infectous pattern and antibiotic sensitivity of Shigella spp. were as follows; The range of percentage of an identified Shigella spp. among total feces and rectal swabs was $1.5{\sim}12.5%$ yearly. The isolation ratios of Shigella spp. per each patient 1.35 for male and 1.19 for female. The isolation ratio of male to female was 1.28:1 in whole group. The isolated Shigella species was 81.0% in S. flexneri, 1.1% in S. boydii and 17% in S. sonnei. The highest number of Shigella spp. was found in August and September according to monthly isolation, on the other hand the lowest number of Shigella spp. was obserbed in March. The seasonal isolation rate of Shigella spp. was 31.7% in Fall, 27.3% in Summer, 21.6% in Winter and 19.3% in Spring. The age specific frequency of Shigellosis was 46.8% in $0{\sim}9$ year group, 8.6% in $10{\sim}19$, 7.2% in $40{\sim}49$ and 6.5% in $50{\sim}59$. The antibiotics showing over 80% susceptibility against Shigella spp. were gentamicin, kanamycin, amikacin, tobramycin, cefoperazone, cefoxitin, cefamandole nafate, cefotaxine and sisomycin.

Purpose: During the COVID-19 pandemic, there have been many cases of converting regular hospital wards into temporary negative pressure isolation wards. The purpose of this study is to evaluate the minimum airflow differences that satisfies the pressure difference criteria(-2.5 Pa) according to airtightness of switching type wards, in preparation for utilization of aging regular wards as negative pressure isolation wards. Methods: Visual inspection and field measurements were conducted using blower door to evaluate airtightness of 5 hospital wards. CONTAM simulation was used to assess the airflow differences when pressure difference between the corridor and wards met the criteria at various levels of airtightness. Results: The ACH₅₀ of evaluated wards ranged from 19.3 to 50.1 h^-1 with an average of 37.0 h^-1, indicating more than four times leakier than other building types. The minimum airflow differences increased as the airtightness of the wards decreased and the size of the wards increased. Implications: When operating rapidly converted negative pressure isolation wards, understanding airtightness is crucial for determining the minimum airflow differences to maintain the pressure differences. The analysis of this study suggests that improving the airtightness of aging rooms is essential and the minimum airflow differences should be suggested considering both the airtightness and size of rooms.
