How to Find Reliable Information About Coronavirus?

By looking at all sources and comparing the results based on who the source is. Since it is a medical subject check sources that are based on medical experts disease research organizations and doctors not politicians.

If you mean overall, number of cases/ deaths/ etc. I've been using these sites....

John Hopkins Covid-19 map/ tracker global and detailed. 

Live Science Coronovirus updates and Map

Guardian virus map US states and world map.

Bing Covid-19 case map/tracker.

All these are computer generated and reported, with graphics, data, info, updated continuously or every 3 hours/ 6 hours etc.

These are the most cited sources for the media and professionals.

They usually have up to date news updates and info too.

John Hopkins and Guardian seem best to me. (Guardian is a top UK global newspaper with US edition).

Skim Google News headlines five times a day.

I go to twitter. I an find the answer to everything right there.
