Is "worded" correctly used?

I had to look that up as it's not a word/term I've ever used in that sense.

According to online MW Dictionary, it means: protected, guarded, shielded, sheltered, covered, screened, sheltered, secured... you get the drift... so, if those apply to the Singaporean, then it's correct.

I doubt that any native English speaker would say that. One might say:

"One Singaporean is still recovering at Samitivej Srinakarin Hospital."

That sounds correct in Singlish but British English speakers might say, "One Singaporean is still in Samitivej Srinakarin Hospital", unless you want to use the term 'hospitalised'.

Do you think you can stop asking that question about 'warded' now Miss Elaine Koh (and a shout out to your predecessor Miss Tan Guatlay)?
