If you look online there are many sites reporting Covid-19 statistics. The websites I’ve listed below are the ones I most often use to cover statistics from the world down to our local Santa Cruz County, Arizona.
Why does data differ between websites? Websites rely upon publicly available data from multiple sources that do not always agree. More frequent updates of a map often result in higher case numbers than may be available from other sources that are updated less frequently. Weekends and holidays can affect recording and reporting frequency.
