I have developed a COVID-19 tracker, namely $1, that shows data maintained by Google and offers accessibility support.

The existing trackers present a lot of information. On contrary to that, virusquery.com displays significantly less data thus making its consumption easier while letting the user to control how much data they wish to see.

By default, the case counts for the last few days are shown and only for your country which is detected automatically. So when on the data page, you only need to activate the Run Query button in order to get data. If the country was detected incorrectly or you'd like to select a different country (or countries) then your selection will be saved so this will need to be done once.

The tracker leaves font size selection and zooming to the browsers driven by user choices while focusing on rendering sensibly under zooming and providing accessibility instructions for screen readers. If you use JAWS then consider switching its Web Verbosity from Medium to High for the first time. Feedback is welcome.
