Global analysis of daily new COVID-19 cases reveals many static-phase countries including the United States potentially with unstoppable epidemic

Figure 1 Daily new cases in typical downward, upward, and static-phase countries over time. A-D: Daily new cases in typical downward (panel A), upward (panel B), and static-phase countries (panels C and D). Other countries of each type are shown in Figure S1, S2, and S4, respectively. Data (as of April 19, 2020) were collected from Worldometer[1]. For each country, the starting date was set when the cumulative confirmed cases reached 1% of the current cumulative ones as of April 19, 2020. Dotted windows in panels C and D show the period (over 14 d) with invariable daily new cases. Results of other countries in these categories are shown in Figures S1, S2, and S4.
