"Do we send her home to a house that hasn't been disinfected - because disinfecting teams aren't functioning."
In the sentence above, does "a house" mean any house or her house? I find it confusing because the sentence used "home", which is an adverb and implies "her house". But, at the same time, it used the indefinite article "a" before "house", which implies the "house" is not a particular house but any house that has not been disinfected. If the "house" were her house, I though using "the house, has not been disinfected" would be more appropriate because we know what particular house the sentence refers to.
Is my reasoning wrong?
