We developed and studied the feasibility of using a mobile App to collect daily data on COVID-19 symptoms and people\u2019s movements.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec002\">\n<jats:title>Methods<\/jats:title>\n<jats:p>We used an open source software \u201cKoBo Toolbox\u201d to develop the App and installed it on low cost smart mobile phones. We named this App \u201c<jats:italic>Wetaase<\/jats:italic>\u201d (\u201c<jats:italic>protect yourself<\/jats:italic>\u201d). The App was tested on 30 selected households from 3 densely populated areas of Kampala, Uganda, and followed them for 3 months. One trained member per household captured the data in the App for each enrolled member and uploaded it to a virtual server on a daily basis. The App is embedded with an algorithm that flags participants who report fever and any other COVID-19 related symptom.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>A total of 101 participants were enrolled; 61% female; median age 23 (interquartile range (IQR): 17\u201336) years. Usage of the App was 78% (95% confidence interval (CI): 77.0%\u201378.8%). It increased from 40% on day 1 to a peak of 81% on day 45 and then declined to 59% on day 90. Usage of the App did not significantly vary by site, sex or age. Only 57\/6617 (0.86%) records included a report of at least one of the 17 listed COVID-19 related symptoms. The most reported symptom was flu\/runny nose (21%) followed by sneezing (15%), with the rest ranging between 2% and 7%. Reports on movements away from home were 45% with 74% going to markets or shops. The participants liked the \u201c<jats:italic>Wetaase<\/jats:italic>\u201d App and recommended it for use as an alert system for COVID-19.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusion<\/jats:title>\n<jats:p>Usage of the \u201c<jats:italic>Wetaase<\/jats:italic>\u201d App was high (78%) and it was similar across the three study sites, sex and age groups. Reporting of symptoms related to COVID-19 was low. Movements were mainly to markets and shops. Users reported that the App was easy to use and recommended its scale up. We recommend that this App be assessed at a large scale for feasibility, usability and acceptability as an additional tool for increasing alerts on COVID-19 in Uganda and similar settings.<\/jats:p>\n<\/jats:sec>","DOI":"10.1371\/journal.pone.0260269","type":"journal-article","created":{"date-parts":[[2021,11,19]],"date-time":"2021-11-19T18:26:19Z","timestamp":1637346379000},"page":"e0260269","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":7,"title":["Feasibility of using a mobile App to monitor and report COVID-19 related symptoms and people\u2019s movements in Uganda"],"prefix":"10.1371","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9423-2472","authenticated-orcid":true,"given":"Levicatus","family":"Mugenyi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rebecca Namugabwe","family":"Nsubuga","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Irene","family":"Wanyana","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Winters","family":"Muttamba","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nazarius Mbona","family":"Tumwesigye","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9761-6095","authenticated-orcid":true,"given":"Saul Hannington","family":"Nsubuga","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2021,11,19]]},"reference":[{"key":"pone.0260269.ref001","article-title":"The epidemiology and pathogenesis of coronavirus disease (COVID-19) outbreak","author":"HA Rothan","year":"2020","journal-title":"Journal of Autoimmunity"},{"key":"pone.0260269.ref002","unstructured":"WHO.
