This popped up last night. The story is actually old
Container ship EVER LUCENT will be arriving Los Angeles in a few hours. She departed Ningbo, China on 21 January. Still no mention on any maritime sites about vessels from China being turned away or quarantined at any port along the coast from Vancouver, Canada to Balboa, Panama.
For planefags: Four USN tracks off San Diego, all appear to be small boys, no CVN or amphib showing so far.
