Hey all 
Recently, I collaborated with one member from the Angular community in Greece and we built a COVID19 web application with Cesium and Angular.
You can check it out in this video that we created NG-COVID: A COVID19 tracking web app built with Angular - YouTube or you can preview the real experience in https://ng-covid19.netlify.app/
The application is currently in version 1 but we are planning to add more Cesium based features in the next versions, so stay tuned 
Any feedback that you have will be greatly appreciated
