tl;dr there ARE sites taking advantage of ppl researching COVID-19 online, but it is NOT the interactive online map from John Hopkins University

⚠️ do not download coronavirus interactive map software/app ⚠️

the John Hopkins University site will not ask you to download extra software to use their online map
