I can't quite figure out how many on the ship are infected...
BNO seem to be keeping an up to date / up to the hour running tally, updated as soon as reports come in and referenced:

OTOH, despite that I'd give BNO a miss overall - their twitter feed especially seems to be full of unreferenced gossip and rumour.
The tally of "serious" cases should be taken with a grain of salt. Within China, it depends where as Hubei reports those cases when clinically diagnosed - other regions there has to be a positive test.
Outside China, only some countries are reporting how the patients are doing, so the total (currently 19 / 684 cases) listed as "serious" will be incomplete.
