Fourteen African swine fever (ASF) outbreaks occurred in the pig farms in the northwestern region of South Korea, near the border with North Korea, from September 16, 2019 to October 9, 2019. Active and passive surveillance on the ASF-infected farms indicated that the infection was limited only to pigsties where the infected pigs were detected on the farm for the first time before further transmission to other pigsties and farms. This early detection could be one of the pivotal factors for the prompt eradication of ASF in domestic pig farms within 1 month in the northwestern region of South Korea.

Background:
Since 2003, the H5 highly pathogenic avian influenza (HPAI) subtype has caused massive economic losses in the poultry industry in South Korea. The role of inland water bodies in avian influenza (AI) outbreaks has not been investigated. Identifying water bodies that facilitate risk pathways leading to the incursion of the HPAI virus (HPAIV) into poultry farms is essential for implementing specific precautionary measures to prevent viral transmission.
Objectives:
This matched case-control study (1:4) examined whether inland waters were associated with a higher risk of AI outbreaks in the neighboring poultry farms.
Methods:
Rivers, irrigation canals, lakes, and ponds were considered inland water bodies.The cases and controls were chosen based on the matching criteria. The nearest possible farms located within a radius of 3 km of the case farms were chosen as the control farms.The poultry farms were selected randomly, and two HPAI epidemics (H5N8 [2014–2016] and H5N6 [2016–2017]) were studied. Conditional logistic regression analysis was applied.
Results:
Statistical analysis revealed that inland waters near poultry farms were significant risk factors for AI outbreaks. The study speculated that freely wandering wild waterfowl and small animals contaminate areas surrounding poultry farms.
Conclusions
Pet birds and animals raised alongside poultry birds on farm premises may wander easily to nearby waters, potentially increasing the risk of AI infection in poultry farms. Mechanical transmission of the AI virus occurs when poultry farm workers or visitors come into contact with infected water bodies or their surroundings. To prevent AI outbreaks in the future, poultry farms should adopt strict precautions to avoid contact with nearby water bodies and their surroundings.

Objective:
In this study, we compared differences based on the gender of Korean emergency physicians to provide basic data for future emergency medicine development plans.
Methods:
We used data from the emergency physician survey (2020) conducted by the Korean Society of Emergency Medicine. A total of 1,303 emergency physicians responded to the survey. We adjusted demographic data relating to age, position, and work duration as an emergency physician, which could affect the differences based on gender. After propensity score matching, we compared working hours, work burden, income, motives for applying for emergency medicine, and future plans of the emergency physicians by sex.
Results:
The total working hours per month and night shifts per month were higher in men compared to the women. The women felt more pressure in the following areas: number of emergency patients, relationships with administrative agencies, insufficient emergency medical technician manpower, patients’ compliance, and relationships with other emergency physicians. Monthly income was higher in men. Women placed a higher value on ‘Acquiring a range of knowledge’ and ‘Degree of interest in working in the emergency room’ than men as motivation for applying for positions in emergency medicine. Regarding future plans, women placed less value on income and more on having enough free time and avoiding burnout. The retirement age was about 3 years lower for women than for men.
Conclusion
This study revealed gender differences in working hours, income, motivation for applying for emergency medicine, work burden, and future plans. It is expected that these differences are caused by physical limitations and socio-cultural backgrounds. It is recommended that more detailed investigations be carried out through qualitative research. These results could help in gender considerations while hiring emergency physicians.
