At the time, it was believed COVID-19 variants were driving the number of cases. However, researchers discovered it was human behavior that played a bigger role.
Researchers found the variants spread faster in states and countries where officials were slower to order lockdowns or enforce mask mandates.
The study was published in the journal “Science Translational Medicine.”
