Pattern analysis of hospital traffic and internet search terms suggest coronavirus outbreak began in China before winter

The video discusses a study by Harvard University researchers suggesting that the coronavirus may have affected Wuhan months before the outbreak was officially acknowledged. The study, which is not yet peer-reviewed, analyzed satellite images of hospital parking lots in Wuhan and found a significant increase in the number of parked vehicles in late 2019 compared to the previous year. This increase is considered a proxy for respiratory patient intake. Additionally, the study noted a rise in internet searches for symptoms like cough and diarrhea in China during the same period.
