The figure above shows the recent growth in the number of confirmed COVID-19 cases for several states, using data through Saturday, March 28.
Dashed lines show exponential growth curves, labeled by doubling time in days. The growth in New York has moderated to a 4-day doubling time; its earlier rapid growth with 1.4-day doubling may have been an effect of rapid expansion in testing, rather than actual spread of the disease.
California has a 3.4-day doubling time, which is slower growth than Colorado with a 3-day doubling time. Recent growth in New Mexico has apparently been variable, but may indicate a doubling time of about 3.5 days.
Data are from several sources: from state reports (for New Mexico and Colorado), from https://ncov2019.live/data, from the Johns Hopkins U. GitHub repository https://github.com/CSSEGISandData/COVID-19, and from https://github.com/COVID19Tracking/covid-tracking-data.
