Human immunodeficiency virus (HIV), a blood-borne viral disease, weakens the immune system and causes opportunistic infections or cancers, which can eventually lead to Acquired Immune Deficiency Syndrome (AIDS). Generally antiretroviral therapy (ART) in HIV infected patients reduces morbidity and mortality, but also increases the risk of liver disease in patients coinfected with Hepatitis B virus (HBV) or Hepatitis C virus (HCV), previously known as the leading cause of death from HIV infection. In this study, HIV positive-sera were investigated seroprevalence of HBV and HCV which were requested for HIV test from 2020 to 2021. Of the total 232 samples, there are 184 cases (79.1%) in hospital, 33 cases (14.2%) in public health center, 6 cases (2.6%) in correctional institution and 2 cases (0.9%) in the military manpower administration. Hepatitis B virus surface antigen (HBsAg) was detected in 13 cases (5.6%) and hepatitis C virus antibody (anti-HCV) in 16 cases (6.9%) and also both in 4 cases (1.7%) of 232 samples. The results of HBsAg and hepatitis B virus core antibody (anti-HBc) for 107 samples were anti-HBc positive in 36 cases (35.6%) and HBsAg positive in 4 cases (1.7%). The results confirmed that coinfection with HBV and HCV was more common in HIV infected people than in the general population in Korea. These findings from this study were provided as fundamental data for HIV infection prevention and ART therapy selection.

This study was aimed to investigate factors that affected the status of wearing personal protective equipment (PPE) for handling poultry carcasses with potential exposure to virulent avian infectious agents. A large outbreak of high pathogenic avian influenza (HPAI) occurred in South Korea in 2014. Many public officers participated for euthanizing and handling livestock carcass. However, several safety issueswith using PPE were revealed. Therefore, a questionnaire survey was conducted for 340 people who participated euthanasia and carcass disposal in the place where HPAI mainly occurred in 2014. It was found that 31.8% of the respondents had ever taken off their protective equipment during operations because of its inconvenience. The most inconvenient PPE was goggles (54.6%), followed by mask (20.2%), latex gloves (11.6%), shoe covers (5.9%) and protective clothing (5.3%). The main complaints about this individual PPE was unclear sight, damp emitted toward eye, sweating, tearing easilyand sweating, respectively. Considering such problems of PPE, new possible directions for improvement of gloves and goggles were suggested. With newly developed rubber coating fabric gloves and conventionally using latex and fabric gloves, H3N2 influenza virus transmission experiment was conducted. Rubber coating fabric gloves showed similar efficiency for blocking virus transmission with latex laboratory gloves and were not easily torn by sharp claws of chicken. In addition, air flow control safety eyewear was suggested to minimize moisture formation. The air flow control system efficiently suppressed moisture formation inside the goggles. Therefore our study will provide more specific directions about new PPE development for safety protection of actual wearers.

Objectives: We analyzed water in waterscape facilities to investigate contamination levels of water-borne pathogens and four test items (pH, turbidity, residual chlorine, and Escherichia coli) at facilities including play fountains, splash parks, and artificial streams from June to October in Suwon City and in the whole of Gyeonggido. Methods: A total of 62 waterscape facility samples were collected from 36 sites and tested for pathogenic Escherichia coli and water-borne viruses that cause hand-foot-and-mouth disease, eye disease, and acute enteritis. Results: None of the water-borne pathogens were detected in waterscape facility samples collected from across Gyeonggi-do that were for pre-inspection for facility management. However, the results of samples from Suwon collected in hot weather and during the school vacation period showed five total inconsistencies in turbidity (four cases) and Escherichia coli (one case). Three out of the four inconsistent samples in turbidity were from the same facility which operated a sand filtration system due to its locational factors close to mountains. Conclusion: We suggest that the waterscape facilities in Gyeonggi-do are managed properly in the respect of microbial contamination and water quality.
