While it is impossible to know whether the news reports are true, it is reported that every FA left the plane, and with their baggage, before the PAX. This suggests the strange confluence of (a) FAs are too sick to continue the flight and divergence is required; (b) upon landing all FAs are so sick as to need to get off the plane before the PAX; but (c) well enough to take their bags.
Again, may be the news reports are inaccurate, but this situation seems a bit fishy. [I know, bad pun.]
