Here, for the first time, the association between Korean meteorological factors and air pollutants and the COVID\u201019 infection was investigated. Data of air pollutants, meteorological factors, and daily COVID\u201019 confirmed cases of seven metropolitan cities and nine provinces were obtained from 3 February 2020 to 5 May 2020 during the first wave of pandemic across Korea. We applied the generalized additive model to investigate the temporal relationship. There was a significantly nonlinear association between daily temperature and COVID\u201019 confirmed cases. Each 1\u00b0C increase in temperature was associated with 9% (lag 0\u201014; OR\u2009=\u20091.09; 95% CI\u2009=\u20091.03\u20101.15) increase of COVID\u201019 confirmed cases when the temperature was below 8\u00b0C. A 0.01\u2009ppm increase in NO<jats:sub>2<\/jats:sub> (lag 0\u20107, lag 0.14, and lag 0\u201021) was significantly associated with increases of COVID\u201019 confirmed cases, with ORs (95% CIs) of 1.13 (1.02\u20101.25), 1.19 (1.09\u20101.30), and 1.30 (1.19\u20101.41), respectively. A 0.1\u2009ppm increase in CO (lag 0\u201021) was associated with the increase in COVID\u201019 confirmed cases (OR\u2009=\u20091.10, 95% CI\u2009=\u20091.04\u20101.16). There was a positive association between per 0.001\u2009ppm of SO<jats:sub>2<\/jats:sub> concentration (lag 0, lag 0\u20107, and lag 0\u201014) and COVID\u201019 confirmed cases, with ORs (95% CIs) of 1.13 (1.04\u20101.22), 1.20 (1.11\u20101.31), and 1.15 (1.07\u20101.25), respectively. There were significantly temporal associations between temperature, NO<jats:sub>2<\/jats:sub>, CO, and SO<jats:sub>2<\/jats:sub> concentrations and daily COVID\u201019 confirmed cases in Korea.<\/jats:p>","DOI":"10.1002\/jmv.26325","type":"journal-article","created":{"date-parts":[[2020,7,21]],"date-time":"2020-07-21T11:11:30Z","timestamp":1595329890000},"page":"878-885","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":52,"title":["Ambient air pollution, meteorology, and COVID\u201019 infection in Korea"],"prefix":"10.1002","volume":"93","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6653-3406","authenticated-orcid":false,"given":"Tung","family":"Hoang","sequence":"first","affiliation":[{"name":"Department of Cancer Biomedical Science National Cancer Center Graduate School of Cancer Science and Policy  Goyang Korea"},{"name":"Institute of Research and Development Duy Tan University  Danang Vietnam"},{"name":"Faculty of Pharmacy Duy Tan University  Danang Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4712-257X","authenticated-orcid":false,"given":"Tho Thi Anh","family":"Tran","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology and Hepatology Nghe An Oncology Hospital  Nghe An Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,7,27]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(20)30185-9"},{"key":"e_1_2_9_3_1","unstructured":"World Health Organization.Coronavirus disease (COVID\u20102019) Situation Reports.2020.https:\/\/www.who.int\/emergencies\/diseases\/novel-coronavirus-2019\/situation-reports.
