The info stuff not the raw data can be old. The data is current, depending only on when govts update the numbers. US, Germany, UK, Spain update throuhhout the day. France and Italy once a day.
I’m talking about the “sublink” within it. For example, this:
https://www.worldometers.info/coronavirus/coronavirus-age-sex-demographics/
That sublink shows that it was last updated on February 29th.; And it has been stuck there ever since.
