A new analysis, led by UArizona Department of Ecology and Evolutionary Biology head and BIO5 associate director Dr. Michael Worobey, indicates that the first COVID-19 outbreak began around February 13th, weeks later than the previously assumed timeline of the outbreak beginning in mid-January. The study provides reason for optimism: It suggests that if COVID-19 cases can be brought down to very low numbers, it’s possible to use techniques such as contact tracing to keep an outbreak under control.
