If someone understands this crude metric as "If you catch it and you show symptoms and you test positive, your likelihood of dieing is roughly (deaths divided by confirmed cases)" then that seems reasonable to me.
"Try to avoid catching it." is reasonable advice, as is "Be aware that you could catch it and be asymptomatic while still being infectious." to discourage people from visiting their grandparents this month.
I don't feel like I'm being misinformed if I divide deaths by confirmed cases, I feel like I'm getting a rough worst-case estimate.
Current fatality rate is less than 1% of confirmed cases.
Currently experts are giving us data and people are giving us sources.
[1] Countries like Iran literally have mass graves at this point and here you are claiming this is overblown by social media.
You really need to stop.
Please stop dividing deaths by confirmed cases and reporting that as mortality rate.
The number of confirmed cases is much, much larger than actual cases, in particular in outbreak zones where testing is very limited.
