People who tested negative, but showed
symptoms — fever, vomiting, sore throat and
diarrhea — were
observed and discharged after 21 days if they were free
of symptoms, while being kept apart from people who tested positive for the disease.
In addition lush growth
of Brassicacea and Poacea species (Poa bulbosa, Eremophyrum triticeum, Leymus ramosus, Elytrigia repens) providing high protein forage, can cause the
observed symptoms of foamy fermentation,
diarrhea and bloating.
