Several studies have suggested the possibility of airborne transmission of infectious diseases such as tuberculosis, pandemic influenza. because the number of patients increases explosively, if infectious disease had a high basic reproduction number, pharmaceutical interventions such as vaccination, chemoprophylaxis in the early stage of epidemic. Thus, non-pharmaceutical interventions such as mask-wearing, installing air cleaners, school closure are important to control and prevent the infectious diseases. However, the current technology on the mask, air cleaning, ventilation, and etc., seems to be not originated from the understanding of infection via airborne transmission. It is important to estimate the aerodynamic behavior of saliva droplets by coughing or speaking in order to understand the phenomena of airborne infection. In addition, the prediction of transmission of infectious diseases through the air is critical to prevent or minimize the damage of infection. In this review, we reviewed the recent studies on the airborne infection by focusing on the aerodynamic characteristics of saliva droplets and modeling of airborne transmission.

Viral, bacterial and fungal infections can be transmitted via allografts such as bone, skin, cornea and cardiovascular tissues. Allogenic bone grafts have possibility of transmission of hepatitis C, human immunodeficiency virus (HIV-1), human T-Cell leukaemia virus (HTLV), tuberculosis and other bacterias. The tissue bank should have a policy for obtaining information from the patient's medical report as to whether the donor had risk factors for infectious diseases. Over the past several years, improvements in donor screening criteria, such as excluding potential donor with "high risk" for HIV-1 and hepatitis infection, and donor blood testing result in the reduction of transmission of these diseases. During tissue processing, many allografts are exposed to antibiotics, disinfectants and terminal sterilization such as irradiation, which further reduce or remove the risk of transmitting diseases. Because the effectiveness of some tissue grafts such as, fresh frozen osteochondral grafts, depends on cellular viability, not all can be subjected to sterilization and processing steps and, therefore, the risk of transmission of infectious disease remains. This article is review of the transmission of considering infectious disease in allogenic bone transplantation and the processing steps of reducing the risk. The risk of viral transmission in allografts can be reduced in several standards. The most important are donor-screening tests and the removal of blood and soft tissues by processing steps under the aseptic environment. In conclusion, final sterilizations including the irradiation, can be establish the safety of allografts.

Implantation of allografts has increased widely with not only the availability of many allogenic bone but also allogenic soft tissues. The aim of tissue banking is to provide surgeons with safe tissues compatible with their intended clinical application. The incidence of tissue transplant-transmitted infection is unknown and can only be inferred from prospective studies. The possibility of donor-to-recipient disease transmission through soft tissue transplantation can be considered by reviewing the risk associated with other transplanted hard tissues. Viral, bacterial, and fungal infections have been transmitted via transplantation of soft tissue allografts such as skin, cornea, dura, pericardium. fascia lata, and heart valves. Corneas have transmitted rabies, Creutzfeldt-Jakob disease (CJD), hepatitis B (HBV), cytomegalovirus (CMV), herpes simplex virus (HSV), bacteria, and fungi. Heart valves have been implicated in transmitting tuberculosis, hepatitis B. HIV-1 and CMV. CJD has been transmitted by dura and pericardium transplants. Skin has transmitted CMV, bacteria, and fungi. Cadaveric skin, pericardium, dura, and fascia lata have been used in dental patients with intra-oral soft tissue injuries and GBR. This study is review of the considering transmission of infectious disease in allogenic soft tissues and guidelines of reducing the risk. Prior to use, many tissues are exposed to antibiotics, disinfectants, and sterilants, which further reduce or remove the risk of transmitted disease. Because some soft tissue grafts cannot be subjected to sterilization steps, the risk of infectious disease transmission remains and thorough donor screening and testing is especially important.

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.

As the main aim of infectious disease epidemiology is to prevent a pathogen transmission, traditional epidemiological studies have focused on the evaluation of individual-level risk factors. But group-level factors as well as individual-level are important in understanding and controlling transmission of infectious diseases, especially sex-transmitted infectious diseases. Multi-level analysis (MLA) is known as a powerful analytical tool for investigating both levels simultaneously. While new cases of HIV/AIDS in Korea are increasing annually, it is urgently needed to establish research system for MLA led by Korea Centers for Disease Control & Prevention.

본 연구는 재난주관방송사인 KBS의 코로나19 관련 보도의 '유형 및 형식', '전문성', '감염병 관련 사안'이 어떻게 나타나는지 '발각', '확산', '회복'이라는 세 시기를 중심으로 살펴보았다. 총 473개의 언론보도를 분석한 결과, 세 시기 모두 감염병 사실을 있는 그대로 알리는 '스트레이트 보도'와 '정보전달 프레임'이 높게 나타났으며 위험 상황을 전달함에 있어서도 '감정적 전달'보다는 '사실전달' 프레임의 비중이 높았다. 하지만 2기에서 감염병 원인을 특정 개인이나 집단에 귀인시키는 '도덕적 평가 프레임'의 비중이 상대적으로 높게 나타났으며, 여전히 전문기자보다 비전문 기자의 비율이 압도적으로 높은 것으로 드러났다. 한편 감염병 관련 사안은 '감염 관리'에 대한 내용이 가장 많았고, '대처'에 관한 정보는 상대적으로 적었다. 본 연구는 위 결과를 바탕으로 향후 감염병 보도를 함에 있어 '보도의 심층성 및 전문성 고양', '특정 주체에게 도덕적 책임을 귀인시키는 보도 행태의 지양', 그리고 '다양한 감염병 관련 정보의 종합적 제시'라는 함의를 제언하였다.

The most important characteristics of coronavirus disease 2019 (COVID-19) transmission that makes it difficult to control are 1) asymptomatic and presymptomatic transmission, 2) low incidence or lack of dominant systemic symptoms such as fever, 3) airborne transmission that may need a high infectious dose, and 4) super-spread events (SSEs). Patients with COVID-19 have high viral loads at symptom onset or even a few days prior to symptom onset, and most patients with COVID-19 have only mild respiratory symptoms or merely pauci-/null-symptoms. These characteristics of the virus enable it to easily spread to the community because most patients are unaware of their potential infectivity, and symptom-based control measures cannot prevent this type of transmission. Furthermore, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is also capable of airborne transmission in conditions such as aerosol-generating procedures, under-ventilated indoor spaces, and over-crowded areas. In this context, universal mask-wearing is important to prevent both outward and inward transmission until an adequate degree of herd immunity is achieved through vaccination. Lastly, the SSEs of SARS-CoV-2 transmission emphasize the importance of reducing contacts by limiting social gatherings. The above-mentioned transmission characteristics of SARS-CoV-2 have culminated in the failure of long-lasting quarantine measures, and indicate that only highly effective vaccines can keep the communities safe from this deadly, multifaceted virus.

H3N8 equine influenza virus (EIV) causes respiratory diseases in the horse population, and it has been demonstrated that EIV can transmit into dogs owing to its availability on receptors of canine respiratory epithelial cells. Recently, we isolated H3N8 EIV from an EIV-vaccinated horse that showed symptoms of respiratory disease, and which has a partially truncated nonstructural gene (NS). However, it is not clear that the NS-truncated EIV has an ability to cross the host species barrier from horses to dogs as well. Here, we experimentally infected the NS-truncated H3N8 EIV into dogs, and monitored their clinical signs and viral load in respiratory organs to determine the virus's transmissibility.
