Страны по разному ведут статистику и иногда единовременно выкидывают ранее неучтенные накопленные данные. Статистические сайты тоже по разному на это реагируют. В целом, от перемены мест слагаемых сумма не меняется.
On April 2, France reported 884 additional deaths that have occurred in nursing homes over the past days and weeks. The French Government did not include these deaths in their official count, as their count only takes into consideration deaths of hospitalized patients. Following international standards of correct inclusion, our statistics will include these deaths, and will add them to the April 2, 2020 count following the attribution criteria of date of report. If and when the French government determines and communicates the correct distribution of these additional deaths over time, we will adjust the historical data accordingly.
A similar issue took place on February 12, when China reported an additional 13,332 new cases in a single day due to a change in how cases were diagnosed and reported in Hubei.
