“…However, examples of misinformation spread through sources other than social media have also been reported, such as the fake news about the shortage of toilet paper due to the COVID-19 pandemic since most toilet papers are made in China. This news spread in Japan in February and March 2020 [ 10 ]. When asked where they received this information, nearly 60% of the participants stated that television (TV) was the most common source [ 11 ].…”

Background The COVID-19 pandemic has caused not only a disease epidemic but also an infodemic. Due to the increased use of the internet and social media, along with the development of communication technology, information has spread faster and farther during the COVID-19 infodemic. Moreover, the increased choice of information sources has made it more difficult to make sound decisions regarding information. Although social media is the most common source of misinformation, other forms of media can also spread misinformation. However, the media sources used by people with high health literacy and COVID-19 knowledge to obtain information are unclear. Furthermore, the association between the use of multiple information sources and health literacy or COVID-19 knowledge is ill-defined. Objective This study aims to examine the following 3 aspects regarding the COVID-19 infodemic: (1) the relationship between health literacy, COVID-19 knowledge, and the number of information sources used; (2) the impact of media use on health literacy; and (3) the impact of media use on COVID-19 knowledge. Methods An online cross-sectional study was conducted in November 2021. Participants were 477 individuals aged 20-69 years. After obtaining consent to participate in the study, participants were asked about sociodemographic indicators, sources of health-related information, health literacy, and COVID-19 knowledge. Sources of health-related information were categorized into 4 types: mass media, digital media, social media, and face-to-face communication. The Spearman rank correlation test was conducted to determine the relationship between health literacy, the number of correct answers to COVID-19 knowledge, and the number of information sources used. Multiple regression analysis was conducted with health literacy and the number of correct answers as dependent variables, the 4 media types as independent variables, and age and sex as adjustment variables. Results Mass media was the most frequently used source of information, followed by digital media, face-to-face communication, and social media. Social media use was significantly higher among individuals aged 20-29 years than among other age groups. Significant positive correlations were found between health literacy, the number of positive responses to COVID-19 knowledge, and the number of information sources used. Multiple linear regression analysis showed that health literacy is associated with access to information from digital media and face-to-face communication. Additionally, COVID-19 knowledge was associated with access to information from mass media, digital media, and face-to-face communication. Conclusions Health literacy and COVID-19 knowledge could be improved using diverse information sources, especially by providing opportunities to use digital media and face-to-face communication. Furthermore, it may be important to improve health literacy and provide accurate knowledge about COVID-19 to young adults.

“…Populations pre-experienced in viral epidemics adopted preventive measures with good risks and bene ts, which is defended, such as social distancing, washing hands, wearing masks, and gargling/rinsing with antiseptic solutions. [18][19][20][21] Since saliva was an important source of virus transmission during the pandemic, protective measures, such as the use of antiseptic gargles were adopted and recommended by several countries and organizations against SARS-CoV-2. 5,10,[21][22][23] Some studies have shown that the use of a mouthwash containing APD can reduce the viral load of SARS-CoV-2, acting as a therapeutic aid in reducing the severity and risk of COVID-19 transmission.…”

Purpose: In this community trial, the objective was to evaluate the incidence of coronavirus disease-2019 (COVID-19) cases in two similar communities in three distinct phases: phase 1 (before the intervention), 2 (during the intervention), and 3 (after the intervention).Methods: The test community received the oral antiseptic intervention (experimental), while the control community did not. The official information agency provided the number of confirmed COVID-19 cases. Data were analyzed according to the three phases per epidemiological week (epi) using the R Core Team (2021) program. The relative risk and 95% confidence intervals between the cumulative incidence values of the test and control communities were calculated for each period. In the test community, a total of 995 residents, over 10 years of age, received two bottles containing 600 ml of mouthwash with antiviral phthalocyanine derivative (APD). The participants were asked to gargle/rinse with of 5 mL of the mouthwash with ADP 3 to 5 times a day, for 1 min, until the end of the bottles. Results: In phases 1 and 3, disease risk between the two communities did not differ significantly (p> 0.05), while in phase 2, disease risk was 54% lower in the test community than in the control community. Conclusion: The use of the APD mouthwash protocol seems to reduce the COVID-19 incidence at the population level, and further studies are needed to confirm its protective effect in different contexts.

“…Some companies provide their business-transaction data to researchers. Especially after the onset of COVID-19, economists collaborated with banks, mobile carriers, and financial technology companies to analyze behaviors during the pandemic (Kaneda, Kubota, and Tanaka 2021; Konishi et al 2021; Kubota, Onishi, and Toyama 2021); however, to our knowledge, few political scientists have used these data. An annotated list of online data resources for Japanese politics work is available in the online appendix, and we encourage researchers to investigate whether analogs exist in their areas or countries of interest.…”

How can scholars conduct field research when there is limited access to the field? This article first identifies how limited and uncertain field access can affect field research and then provides recommendations to address these challenges. We focus on conducting field research in Japan because of our substantive expertise, but we believe that the problems and solutions outlined in this article are applicable to a broad range of countries. Our hope is that this article contributes to the developing literature on conducting research during times of emergency and to the larger literature on best practices for field research.
