Chinese authorities are testing millions of people, imposing lockdowns and shutting down schools after multiple locally transmitted coronavirus cases were discovered in three cities across the country last week.

As temperatures drop, large-scale measures are being enacted in the cities of Tianjin, Shanghai and Manzhouli, despite the low number of new cases compared to the United States and other countries experiencing new waves of infections.
