With the widespread and increasing number of cases of Coronavirus Disease (2019) globally, countries have been taking preventive measures against this pandemic. However, there is no universal agreement across cultures on whether wearing face masks are an effective physical intervention against disease transmission. We investigated the relationship between mask wearing and COVID-19 among close contacts of COVID-19 patients in the Hiroshima Prefecture, Japan. In the Hiroshima Prefecture, a COVID-19 form adapted from the reporting form, “Japanese Surveillance in Post-Extreme Emergencies and Disasters”, was developed to collect data from COVID-19 patients’ close contacts under active epidemiological surveillance at Public Health Centers. The relative risk of COVID-19 for mask users versus non-mask users was calculated. A total of 820 interviewees were included in the analysis and 53.3% of them responded that they wore masks. Non-mask users were infected at a rate of 16.4%, while mask users were infected at a rate of 7.1%. Those who wore masks were infected at a rate of 0.4 times that of those who did not wear masks. (RR = 0.4, 95%CI = 0.3–0.6; Adjusted RR = 0.6, 95%CI = 0.3–0.9). These findings implied that COVID-19 could be avoided to a certain degree by wearing a mask.

Interactive communication and the ability to consider feedback are critical for linking health professionals and the community. Goto and colleagues developed and conducted health literacy training workshops for public health nurses after the 2011 nuclear accident in Fukushima to improve their communication skills. The present study aimed to examine the association between past workshop attendance and nurses’ attitudes toward feedback from community residents. We conducted a questionnaire survey with 723 public health nurses in Fukushima and analyzed differences in feedback acceptance, work environment, basic characteristics, and health literacy levels between health literacy workshop attendees and non-attendees. Among 582 respondents, 19.4% were past attendees and showed a higher likelihood of accepting feedback from community residents (amount: adjusted odds ratio [aOR] = 1.87, 95% confidence interval [CI]: 1.21–2.88; specificity: aOR = 1.69, 95%CI: 1.09–2.61; satisfaction: aOR = 2.34, 95%CI: 1.50–3.65) than did non-attendees after adjusting for other variables. Furthermore, work engagement was associated with positive feedback acceptance (amount: aOR = 1.43, 95%CI: 1.03–1.98; specificity: aOR = 1.57, 95%CI: 1.12–2.20; satisfaction: aOR = 1.97, 95%CI: 1.38–2.81). We note the importance of creating a better work environment as well as a training system at the organizational level that encourages public health nurses to learn about health literacy and to improve their communication skills. This could improve professional/community relationships, increase the accessibility of health information for the public, and ultimately improve community health.

The “Creative Heath” project, a participatory school activity to foster community resilience, was implemented in Fukushima, Japan, and children’s experiences of the project were assessed both quantitatively and qualitatively. The project consists of three workshops: BODY, FOOD, and ACT, with activities to facilitate students’ scientific and creative thinking, working in teams, presenting, and expressing their opinions. The first two schools participated with 105 students aged 9–11 years old. Before and after each workshop, students were given questionnaires to rate their satisfaction with their own health (BODY), local foods (FOOD), and the community at large (ACT) on a five-level scale, with space to add free comments. Ratings for BODY and FOOD changed significantly, and the proportion of students who increased their rating of an evaluation indicator after each workshop was 25% for BODY, 28% for FOOD, and 25% for ACT. Text analysis of free comments showed that students in the “increased” group appreciated presenting, measuring, learning connections between nutrition and health, and working collaboratively with peers. Children perceived their health and the foods in their community more positively after participating. Moreover, the Creative Health project could be a way to enhance children’s creativity and autonomy as agents of change in the community.

Introduction: In the last ten years, Japan has experienced several large-scale earthquakes with devastating social and health impacts. Earthquakes directly and indirectly cause a variety of health problems. Further investigation is required to increase preparedness and preventive efforts. In response to the Hokkaido Eastern Iburi Earthquake on September 6, 2018, 32 Emergency Medical Teams (EMTs) employed the Japanese version of Surveillance in Post-Extreme Emergencies and Disasters (J-SPEED) as a national standard daily reporting template, gathering data on the number and type of health problems treated. Study Objective: The purpose of the study is to conduct a descriptive epidemiology study using the J-SPEED data to better understand the health problems during the earthquake disaster. Methods: Reported items in J-SPEED (Ver 1.0) form were analyzed by age, gender, and time to better understand the health issues that have arisen from the earthquake. Results: Most consultations (721; 97.6%) occurred between Day 1 and Day 13 of the 32-day EMT response. During the response period, disaster stress-related symptoms were the most common health event (15.2%), followed by wounds (14.5%) and skin diseases (7.0%). Conclusion: The most often reported health event during the response period was stress-associated illnesses related to disasters, followed by wounds and skin conditions. The health consequences of natural disasters depend on diverse local environment and population. As a result, this initial study was hard to generalize; however, it is expected that data accumulated using the J-SPEED system in the future will strengthen and extend the conclusions.

It is crucial to provide mental health care following a disaster because the victims tend to experience symptoms such as anxiety and insomnia during the acute phase. However, little research on mental health during the acute phase has been conducted, and reported only in terms of the temporal transition of the number of consultations and symptoms. Thus, the aim of the study was to examine how mental health care needs are accounted for in the overall picture of disaster relief and how they change over time. Using data from the Japanese version of Surveillance in Post-Extreme Emergencies and Disasters (J-SPEED), we assessed the mental health of injured and ill patients to whom Emergency Medical Teams (EMTs) were providing care during the acute period of a disaster. Approximately 10% of all medical consultations were for mental health issues, 83% of which took place within the first 2 weeks after the disaster. The findings showed that, from the start of the response period to the 19th response day, the daily proportion of mental health problems declined substantially, and then gradually increased. Such a V-shaped pattern might be helpful for identifying phase changes and supporting the development of EMT exit strategies.

Background: Rainfall-induced floods represented 70% of the disasters in Japan from 1985 to 2018 and caused various health problems. To improve preparedness and preventive measures, more information is needed on the health problems caused by heavy rain. However, it has proven challenging to collect health data surrounding disasters due to various inhibiting factors such as environmental hazards and logistical constraints. In response to the Kumamoto Heavy Rain 2020, Emergency Medical Teams (EMTs) used J-SPEED (Japan-Surveillance in Post Extreme Emergencies and Disasters) as a daily reporting tool, collecting patient data and sending it to an EMTCC (EMT Coordination Cell) during the response. We performed a descriptive epidemiological analysis using J-SPEED data to better understand the health problems arising from the Kumamoto Heavy Rain 2020 in Japan. Methods: During the Kumamoto Heavy Rain 2020 from July 5 to July 31, 2020, 79 EMTs used the J-SPEED form to submit daily reports to the EMTCC on the number and types of health problems they treated. We analyzed the 207 daily reports, categorizing the data by age, gender, and time period. Results: Among the 816 reported consultations, women accounted for 51% and men accounted for 49%. The majority of patients were elderly (62.1%), followed by adults (32.8%), and children (5%). The most common health issues included treatment interruption (12.4%), hypertension (12.0%), wounds (10.8%), minor trauma (9.6%), and disaster-related stress symptoms (7.4%). Consultations followed six phases during the disaster response, with the highest occurrence during the hyperacute and acute phases. Directly disaster-related events comprised 13.9% of consultations, indirectly related events comprised 52.0%, and unrelated events comprised 34.0%. As the response phases progressed, the proportions of directly and indirectly related events decreased while that of unrelated events increased. Conclusion: By harnessing data captured by J-SPEED, this research demonstrates the feasibility of collecting, quantifying, and analyzing data using a uniform format. Comparison of the present findings with those of two previous analyses of J-SPEED data from other disaster scenarios that varied in time, location, and/or disaster type showcases the potential to use analysis of past experiences to advancing knowledge on disaster medicine and disaster public health.
