Bassett"],"abstract":"Multiple studies have suggested the spread of COVID-19 is affected by factors such as climate, BCG vaccinations, pollution and blood type. We perform a joint study of these factors using the death growth rates of 40 regions worldwide with both machine learning and Bayesian methods. We find weak, non-significant (< 3$\\sigma$) evidence for temperature and relative humidity as factors in the spread of COVID-19 but little or no evidence for BCG vaccination prevalence or $\\text{PM}_{2.5}$ pollution. The only variable detected at a statistically significant level (>3$\\sigma$) is the rate of positive COVID-19 tests, with higher positive rates correlating with higher daily growth of deaths.","url_abs":"https://arxiv.org/abs/2007.05542v1","url_pdf":"https://arxiv.org/pdf/2007.05542v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"climate-bcg-effects-on-covid-19-death-growth","repo_url":"https://github.com/chrisfinlay/covid19","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
