NOTE: As of April 13, 2024, the Coronavirus Tracker is no longer being updated due to the unfeasibility of providing statistically valid global totals, as the majority of countries have now stopped reporting. However, historical data remain accessible. Worldometer delivered the most accurate and timely global statistics to users and institutions around the world at a time when this was extremely challenging. We thank everyone who participated in this extraordinary collaborative effort.
COVID-19 Coronavirus / California Sources

We we are preparing a proper page, bur for now listing them all here as there is no room on the table.
