- Abstract: The primary objective of this study was to collect evidence that individuals who use hot spring facilities and public baths have a low risk of being infected with COVID-19. The secondary objective was to comprehensively summarize the research issues that remain to be explored in the field of balneology considering results of previous research. Literature databases used were CINHAL, Cochrane Library (Clinical Answer, Cochrane Protocol, Cochrane Review, Editorials, Special Collections, Trials), Ichushi Web (in Japanese), MEDLINE, and Web of Science Core Collection. For each database, we selected results from the time it was opened through July 26, 2021. When intervention studies and experimental were searched, the following modified PICOS was used the following: P (Participant: no restrictions on the presence or absence of illness), I (Intervention: normal breathing or intentional sneezing, coughing, conversation), C (Comparison: no restrictions), O (Outcome: markers that simulate the flow of indoor air, the dynamics of droplets, and droplets in bathrooms and dressing rooms), and S (Study design: including intervention studies and experiments without a control group). For observational studies, PECOS included: P (participants: unlimited with or without disease), E (Exposure: public bathing facility), C (comparison: unrestricted), and S (study design: cross-sectional study, cohort study, and case-control study). For the primary objective, no studies met the eligibility criteria, and at the time of this study there was no evidence that the use of hot spring facilities or public baths presented a low risk of being infected with COVID-19. Regarding the secondary objective, there were 15 relevant studies. In the context of a society that is strongly influenced by COVID-19, our literature review identified four research issues: “A. Use of hot spring facilities and public baths has a low risk of COVID-19 infection”, “B. The quality of hot springs and the room temperature and water temperature of public baths make SARS-CoV-2 inactivate/attenuate”, “C. Hot spring facilities, public baths, bathing habits at home lead to prevention of COVID-19 and alleviation of symptoms”, “D. Bathing for survivors of COVID-19 is effective for various rehabilitation of patients”. Suitable research approaches for each issue would be required in order to grasp each evidence.
