CSSE seems to be the most up-to-date aggregate source, though their Github repo is lagging half a day behind the map at here: https://gisanddata.maps.arcgis.com/apps/opsdashboard/index.h....
Diversity of sources and information is good anyway, barring some caveats. There is more than just raw numbers at play; you need a variety of sources to see impacts on daily life, how people are preparing, etc. I follow CBC (Canada), some fellow humans on twitter, and especially appreciate the stuff this guy puts out; https://twitter.com/balajis
He's not a random guy; https://twitter.com/balajis/status/1228752554022068226 but he's also not my only source.
[Edit: I also didn't get my suspicion of China's numbers from him or anyone in particular; I follow China a lot and it's my own conclusion. In January I personally saw packed hospitals and dozens of dead bodies in twitter videos, and it's not exactly easy or safe to get those videos out.]
Maybe I've just been following the topic a lot more than other people. I can understand not having time for it. I have a respiratory condition, and live with an elderly person, so I actually worked my last day as a barista today in order to eliminate public contact. Where I am the virus probably won't come for a couple to a dozen weeks, if ever, but it's still a precaution I can afford to take so I did (I can consult from home).
Also I love tinfoil hats, thank you <3 (Sorry for the long thread, kinda hoping we get collapsed)
