what should He do? A mother of twins (boys) tested HIV +ve, the Husband -ve

After a joyful celebration of two bouncing baby boys, which was not diagnosed. A mother of twins suddenly discovered her babies were costantly falling sick which was traced to the babies testing positive to HIV virus, the mother was also tested and the result showed she was also positive leading to the twins becoming infected with the virus. Further test was done showing the husband and the father of twins (2boys) tested negative.
Currently the Husband is not aware of the fact that his wife and children (twins) have tested positive to HIV.

Should she tell the Husband?
If the Husband knows what should he do?

All die na die on this one oooo

But with the kids falling ill, there is no way the father would not know, Thus its better she tells now.

Even though, a lot of things can happen after, fights, misplaced trust, questions, or even separation but well, this is life...life goes on

Na lose lose for the mother sha,
She talk true,na die.
She lie and d pikins die,she die again.
Wetin she dey find about is the real question.

Nice one Niyi

See this man oooh (Husband) boasting he's not anyway infected with the virus.
