A present COVID-19 has high transmission rates worldwide, including in small Brazilian cities such as Iju\u00ed. Located in the northwest part of the state of Rio Grande do Sul (RS) and with a population of 83,475, Iju\u00ed was selected as the site of a population-based survey involving 2,222 subjects, from April to June 2020. Subjects were tested for the presence of antibodies against coronavirus (SARS-CoV-2) and answered questions regarding social distance adherence (SDA), daily preventive routines (DPR), comorbidities, and sociodemographic characteristics. In parallel, the local government registered the official COVID-19 cases in Iju\u00ed, as well as the mobile social distancing index (MSDI). In this study, we demonstrate that there was a decrease in the levels of SDA, DPR and MSDI before the beginning of COVID-19 community transmission in Iju\u00ed. Furthermore, we provide predictions for the number of COVID-19 cases, hospitalizations, and deaths in the city. We conclude that insufficient social distancing, as evidenced by different methods, may be related to the rapid increase of COVID-19 cases in Iju\u00ed. Our study predicts an approaching outbreak of COVID-19 in Iju\u00ed through community spread, which could be avoided or attenuated with increased levels of social distancing among the population.<\/jats:p>","DOI":"10.1371\/journal.pone.0246520","type":"journal-article","created":{"date-parts":[[2021,2,17]],"date-time":"2021-02-17T13:35:28Z","timestamp":1613568928000},"page":"e0246520","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":13,"title":["Insufficient social distancing may contribute to COVID-19 outbreak: The case of Iju\u00ed city in Brazil"],"prefix":"10.1371","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1242-5423","authenticated-orcid":true,"given":"Thiago Gomes","family":"Heck","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3740-7560","authenticated-orcid":true,"given":"Rafael Z.","family":"Frantz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5578-4656","authenticated-orcid":true,"given":"Matias Nunes","family":"Frizzo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos Henrique Ramires","family":"Fran\u00e7ois","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0300-1511","authenticated-orcid":true,"given":"Mirna Stela","family":"Ludwig","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9598-4193","authenticated-orcid":true,"given":"Marilia Arndt","family":"Mesenburg","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5339-0039","authenticated-orcid":true,"given":"Giovano Pereira","family":"Buratti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8253-1723","authenticated-orcid":true,"given":"L\u00edgia Beatriz Bento","family":"Franz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1441-9294","authenticated-orcid":true,"given":"Evelise Moraes","family":"Berlezi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2021,2,17]]},"reference":[{"key":"pone.0246520.ref001","article-title":"Clinical course and risk factors for mortality of adult inpatients with COVID-19 in Wuhan, China: a retrospective cohort study","author":"F Zhou","year":"2020","journal-title":"Lancet"},{"key":"pone.0246520.ref002","article-title":"A new coronavirus associated with human respiratory disease in China","author":"F Wu","year":"2020","journal-title":"Nature"},{"key":"pone.0246520.ref003","article-title":"The epidemiological characteristics of an outbreak of 2019 novel coronavirus diseases (COVID-19) in China","year":"2020","journal-title":"Zhonghua Liu Xing Bing Xue Za Zhi"},{"key":"pone.0246520.ref004","unstructured":"World Health Organization (WHO).
