France

France does not report new data for cases every day. Instead it publishes periodic updates that are “back-distributed” across the database, meaning any new figures are applied to their respective previous days. The daily cases totals reported on the Coronavirus Resource Center are derived by subtracting the previous day's cumulative case count from the current day's cumulative case count. Until we modify the data to reflect France's back distribution, the count may appear as a spike in the data. Additional information about France's data can be found here: https://github.com/CSSEGISandData/COVID-19/issues/2459

Reduced counts in U.S. cases and deaths are the result of states and territories not reporting the information for some or all of the weekend. Those states and territories are: Alaska, Colorado, Connecticut, District of Columbia, Florida, Georgia, Guam, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Massachusetts, Michigan, Minnesota, Mississippi, Montana, Nebraska, Nevada, New Hampshire, New Mexico, North Carolina, Northern Mariana Islands, Oklahoma, Rhode Island, South Carolina, South Dakota, Tennessee, Utah, U.S. Virgin Islands, Virginia, Washington, West Virginia, Wisconsin, and Wyoming. Typically, these states' Monday updates include the weekend totals.
