The woman in the photo is HIV positive while the husband and the children are negative to the deadly virus.
It's real. HIV negative man can impregnate a HIV positive lady without getting infected.
All they need is to place the man on drug and the lady should continue taking her anti-viral drug to reduce the viral load so that there won't be any chance of contamination.
During pregnancy the lady should continue going for checkup and she should continue taking her drug so that the baby can't contact the viral infection.
"Window period" when an HIV patients blood is screened during that window period it will show a false negative result which is Negative. Unless an Eliza method is used to screen that blood which most federal and state hospital doesn’t have.
