@tanguatlay,
That's not how I would put it. I would say 'hospitalized'.
ward
verb
past tense: warded; past participle: warded
1.
ARCHAIC
guard; protect.
"it was his duty to ward the king"
2.
SE ASIAN
admit to or care for in a hospital ward.
So, if you're in SE Asia, apparently you would use it that way.
