Yesterday, the United States surpassed China, becoming the world leader in COVID-19 infections. It’s not hard to understand why. Social distancing remains very uneven.

It uses data from anonymized mobile devices to trace the movement of Spring Break partiers who congregated at one single Ft.

It’s a quick case study showing how an infectious disease can spread through a country that wants to remain mobile come hell, pandemic, or high water.
