Still unclear if there is a respiratory component and if the epidemic has been halted.
Food for thought
Research of reported signs, not including respiratory, could be several uncommon diseases caused at point source vs. communicable:
Vibreo vulnificus (if seafood is in diet)
Novel disease potential:
Zoonotic disease transmission to human (perhaps by ingestion of diseased meat) - African Swine Fever - the disease in pigs is similar in signs/symptoms (except a pig can't tell you it has a headache )
