This can be of great help given the critical, if not dramatic need for complementary monitoring approaches that work on a population level and inform public health decisions in real time. This study of Google search patterns, which was motivated by the fears of individuals in the face of a pandemic, can be useful in anticipating the development of the pandemic.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2196\/23518","type":"journal-article","created":{"date-parts":[[2020,10,26]],"date-time":"2020-10-26T22:23:06Z","timestamp":1603750986000},"page":"e23518","source":"Crossref","is-referenced-by-count":46,"title":["COVID-19 Symptom-Related Google Searches and Local COVID-19 Incidence in Spain: Correlational Study"],"prefix":"10.2196","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8283-4062","authenticated-orcid":false,"given":"Alberto Jimenez","family":"Jimenez","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5241-9725","authenticated-orcid":false,"given":"Rosa M","family":"Estevez-Reboredo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3753-4511","authenticated-orcid":false,"given":"Miguel A","family":"Santed","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8776-4489","authenticated-orcid":false,"given":"Victoria","family":"Ramos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2020,12,18]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(20)30421-9"},{"key":"ref2","unstructured":"Coronavirus disease 2019 (COVID-19) Situation Report \u2013 94World Health Organization202004232020-09-06https:\/\/www.who.int\/docs\/default-source\/coronaviruse\/situation-reports\/20200423-sitrep-94-covid-19.pdf"},{"key":"ref3","unstructured":"Coronavirus disease (COVID-19) pandemicWorld Health Organization Europe2020-09-06https:\/\/www.euro.who.int\/en\/health-topics\/health-emergencies\/coronavirus-covid-19"},{"key":"ref4","doi-asserted-by":"crossref","unstructured":"WHO Coronavirus Disease (COVID-19) DashboardWorld Health Organization2020-06-10https:\/\/covid19.who.int\/","DOI":"10.46945\/bpj.10.1.03.01"},{"key":"ref5","unstructured":"ChuBQureshiSPredicting the COVID-19 Pandemic in Canada and the USIdeas202005052020-07-30https:\/\/ideas.repec.org\/p\/car\/carecp\/20-05.html"},{"key":"ref6","unstructured":"ImaiNDorigattiICoriADonnellyCRileySFergusonNMReport 2: Estimating the potential total number of novel Coronavirus (2019-nCoV) cases in Wuhan City, ChinaImperial College London COVID-19 Response Team202001222020-09-12https:\/\/www.imperial.ac.uk\/media\/imperial-college\/medicine\/sph\/ide\/gida-fellowships\/Imperial-College-COVID19-update-epidemic-size-22-01-2020.pdf"},{"key":"ref7","unstructured":"reichlab\/covid19-forecast-hub: Projections of COVID-19, in standardized formatGitHub2020-09-12https:\/\/github.com\/reichlab\/covid19-forecast-hub"},{"key":"ref8","first-page":"244","volume":"2006","author":"Eysenbach, G","year":"2006","journal-title":"AMIA Annu Symp Proc"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1038\/nature07634"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0003955"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.2196\/13439"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.2807\/1560-7917.ES.2020.25.10.2000199"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijid.2020.03.021"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijid.2020.04.033"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.2139\/ssrn.3585532"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.14218\/ERHM.2020.00023"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.2196\/19702"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1101\/2020.05.01.20087858"},{"key":"ref19","unstructured":"FAQ about Google Trends dataTrends Help2020-09-06https:\/\/support.google.com\/trends\/answer\/4365533?hl=en"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.2196\/10919"},{"key":"ref21","unstructured":"cansancio -sociedad -
