An ecological study was conducted using two publicly available datasets: surveillance on infectious diseases collected by the Japanese government and COVID-19 community mobility reports presented by Google. The COVID-19 community mobility reports demonstrated percentage reductions in the movement of people over time in groceries and pharmacies, parks, and transit stations. We compared the weekly trends in the number of patients with droplet-transmissible PIDs identified in 2020 with those identified in the previous years (2015\u20132019) and assessed the correlations between the numbers of patients and percentage decreases in human mobility during 2020. Despite experiencing their peak seasons, dramatic reductions were found in the numbers of patients with pharyngoconjunctival fever (PCF) and group A streptococcal (GAS) pharyngitis after the tenth week of 2020. Beyond the 20th week, no seasonal peaks were observed in the number of patients with all PIDs identified in 2020. Significant correlations were found between the percentage decreases in human mobility in transit stations and the number of patients with hand-foot-and-mouth disease (Pearson correlation coefficient [95% confidence interval]: 0.65 [0.44\u20130.79]), PCF (0.47 [0.21\u20130.67]), respiratory syncytial virus infection (0.45 [0.19\u20130.66]), and GAS pharyngitis (0.34 [0.06\u20130.58]). The highest correlations were found in places underlying potential human-to-human contacts among adults. These findings suggest that reductions in human mobility for adults might contribute to decreases in the number of children with droplet-transmissible PIDs by the potential prevention of adult-to-child transmission.<\/jats:p>","DOI":"10.3390\/ijerph19116941","type":"journal-article","created":{"date-parts":[[2022,6,6]],"date-time":"2022-06-06T10:08:24Z","timestamp":1654510104000},"page":"6941","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Human Mobility and Droplet-Transmissible Pediatric Infectious Diseases during the COVID-19 Pandemic"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2660-530X","authenticated-orcid":false,"given":"Ryusuke","family":"Ae","sequence":"first","affiliation":[{"name":"Division of Public Health, Center for Community Medicine, Jichi Medical University, Yakushiji 3311-1, Shimotsuke 329-0498, Tochigi, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8625-0195","authenticated-orcid":false,"given":"Yoshihide","family":"Shibata","sequence":"additional","affiliation":[{"name":"Division of Public Health, Center for Community Medicine, Jichi Medical University, Yakushiji 3311-1, Shimotsuke 329-0498, Tochigi, Japan"},{"name":"Department of Electrical and Computer Engineering, National Institute of Technology, Gifu College, 2236-2 Kamimakuwa, Motosu 501-0495, Gifu, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshiki","family":"Furuno","sequence":"additional","affiliation":[{"name":"Advanced Course for Interdisciplinary Technology Development, National Institute of Technology, Gifu College, 2236-2 Kamimakuwa, Motosu 501-0495, Gifu, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teppei","family":"Sasahara","sequence":"additional","affiliation":[{"name":"Division of Public Health, Center for Community Medicine, Jichi Medical University, Yakushiji 3311-1, Shimotsuke 329-0498, Tochigi, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6654-1481","authenticated-orcid":false,"given":"Yosikazu","family":"Nakamura","sequence":"additional","affiliation":[{"name":"Division of Public Health, Center for Community Medicine, Jichi Medical University, Yakushiji 3311-1, Shimotsuke 329-0498, Tochigi, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8990-5265","authenticated-orcid":false,"given":"Hiromichi","family":"Hamada","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Tokyo Women\u2019s Medical University Yachiyo Medical Center, 477-96 Owada-Shinden, Yachiyo 276-0046, Chiba, Japan"},{"name":"Department of Pediatrics, Graduate School of Medicine, Chiba University, 1-8-1 Inohana, Chuo-ku, Chiba-shi 260-8670, Chiba, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e221","DOI":"10.1097\/INF.0000000000002811","article-title":"Facing SARS-CoV-2 pandemic at a COVID-19 regional children\u2019s hospital in Italy","volume":"39","author":"Campana","year":"2020","journal-title":"Pediatr.
