I guess I wasn't being pedantic enough. SARS-CoV-2 causing COVID-19 lung infections doesn't seem to be headline-worthy, let alone "silent".

It's "silent" because people weren't getting diagnosed properly before.

Why would you check for pneumonia in a guy that comes in presenting stab wounds and reports no difficulty breathing?

Only now because with increased testing and experience are doctors realizing that many people have a pneumonia that doesn't present like pneumonia.
