抄録 | The novel coronavirus disease (COVID-19) pandemic that began in 2019 is yet to end, as of the summer of 2022. During the pandemic, community-acquired infections spread easily to healthcare-associated facilities, resulting in COVID-19 clusters among high-risk individuals that have been difficult to contain. Our regional base hospital also experienced a nosocomial cluster of COVID-19 in October 2020 that took 30 days to contain and affected 9 hospital staff and 14 patients. Six patients died due to COVID-19, and six died due to COVID-19-related complications. Two patients were discharged alive. Patient characteristics included ① advanced age (79.0±8.1 years), ② dementia (64.3%), ③ low Prognostic Nutrition Index (31.1 ±7.9), ④ zinc deficiency (50.2±13.1μg/dL), ⑤ vitamin C deficiency (1.6±1.9μg/mL), ⑥ elevated urea nitrogen-to-creatinine ratio (27.4±23.5), ⑦ anticancer and immunosuppressive drug use (78.6%), and ⑧ malignancy (75.6%). This cluster had a very high mortality rate, but the viral spread was contained in a short period. Algorithmizing the cluster response was crucial to controlling this cluster. We report on our actual cluster response algorithm, as well as our strategy and response procedure during the pandemic. |

抄録 | Coronavirus disease 2019 has spread worldwide and has yet to be contained. The Japanese government has taken measures against the occurrence of clusters. However, there has little evaluation of the occurrence of the clusters and their changes. Therefore, we investigated the occurrence of the clusters in medical institutions and elderly care facilities in Okayama Prefecture. We compared the characteristics of the clusters that occurred in each of the wave between October 21, 2020, and September 30, 2021, by using the data published that interval. As a case study, we also evaluated the characteristics of positive patients at a medical institution over where a cluster occurred in case the fourth wave. The overall number of cluster outbreaks decreased with the spread of vaccination. In the fourth wave, there was a period in which the vaccination of staff members at medical institutions became widespread, while patients or facility users were unvaccinated, resulting in a longer convergence period and an increase in the number of positive cases among patients relative to the number of staff members. The impact of the spread of vaccination and the duration of immunity acquired after vaccination on the occurrence of clusters should be closely monitored in the future. |

抄録 | Japan experienced four major epidemic periods (i.e., the 3rd-6th waves) of COVID-19 from January 2020 to March 2022. A different strain predominated in each period: the wild-type strain, an Alpha variant, a Delta variant, and an Omicron variant were predominant in waves 3, 4, 5, and 6, respectively. In this study, we conducted a descriptive analysis to investigate the differences in symptoms and severity during each epidemic period. We analyzed a total of 31,037 patients with COVID-19 who were reported to the Okayama City Public Health Center between February 1, 2020 and March 31, 2022. We described and compared the proportion of symptoms, the number and proportion of severe COVID-19 cases, and the number and proportion of deaths for each epidemic period. We also compared the proportion of severe COVID-19 cases depending on the number of vaccinations for the 5th and 6th waves. Differences in symptoms and severity were observed in each epidemic period. In the 5th and 6th waves, the results suggested that vaccination had a preventive effect against severe COVID-19. |

抄録 | This paper presents the results of a series of surveys conducted from July 2021 to March 2023 to investigate the post-vaccination adverse reactions to the mRNA-1273 (Moderna) vaccine among faculty, staff, and students at Okayama University. These studies complement the official surveys conducted by the Ministry of Health, Labour and Welfare (MHLW) and provide a more representative picture of adverse reactions in the general population including large numbers of healthy young people. Pain, swelling, redness at the injection site, fever, headache, and malaise were the main adverse reactions reported. The proportion of adverse reactions was generally higher after the second vaccination and decreased with each additional vaccination. No statistically significant differences in the adverse reactions were found for males and females and those with/without a history of allergy, but a lower proportion of fever was observed in older participants and those with underlying medical conditions. We also evaluated the association between adverse reactions and antibody titers after the third vaccination and found no significant differences in antibody levels one month after vaccination. This series of studies highlights the importance of conducting surveys in diverse populations to provide a more representative picture of post-vaccination adverse reactions during a pandemic. |

抄録 | Arts festivals have become increasingly popular in various parts of Japan in recent years. The purpose of this study was to investigate the relationships between arts festival activities participation at the Setouchi Triennale and the health of residents in the town of Naoshima. This was a cross-sectional study. Questionnaires were distributed to all residents of Naoshima who were 20 years old or older (n=2,588). We analyzed responses from 708 people. The associations between arts festival activities participation and health (measured by self-rated health) were analyzed using logistic regression analysis as the primary outcome. Kessler’s psychological distress scale scores were also analyzed in the same manner as the primary outcome. The participating group had an adjusted odds ratio of 1.86 (95% confidence interval: 1.03-3.33) for higher self-rated health compared with those who did not participate. Kessler’s psychological distress scale results showed that the participating group had an adjusted odds ratio of 3.23 (95% confidence interval: 1.19-8.81) for lower psychological distress compared with those who did not participate. In conclusion, arts festival activities participation was associated with higher self-rated health and lower psychological distress. However, caution must be taken in regard to generalizability and causality when interpreting these results. |
