- Studies were conducted by University of Toronto’s Dalla Lana School of Public Health and MIT Sloan School of Management.
- The University of Toronto looked at a total of more than 375,600 confirmed COVID-19 cases.
- Their results showed little or no association between latitude or temperature with a rise in COVID-19 cases and a weak association between humidity and fewer cases.
- Hazhir Rahmandad, an associate professor of system dynamics at MIT Sloan School of Management, analyzed more than 3,700 locations between December 2019 and April 2020.
- They found only a slightly lower transmission risk, about a 1.7 percent reduction per 1 degree Fahrenheit, once temperatures rose above 77 degrees F.
