it always was, as I've been saying throughout this thread.
exponential growth.
in a week, numbers raising in the "hundreds per day" will become thousands and then tens of thousands.
That really hasn't happened in China though. With China the numbers could be of course bs but Wuhan region has seen huge decline in cases from the first outbreak. Also in South Korea we have not seen any exponential growth after the outbreak started and more like steady around 200 a day (and they test far more people than any other country at the moment)
