She lost her virginity in childhood due to an accident – should she conceal that from her husband?

There is a Muslim woman who had an accident when she was small, and lost her virginity as a result. She has got married but the marriage has not been consummated yet. In another case, a woman had the same accident and now religiously-committed brothers want to propose marriage to her. They are both confused as to what is better in their case. Should the one who is married tell her husband before he consummates the marriage or should she keep quiet about it? Should the one who is not married yet conceal this matter lest the news spread and people think badly of her? It happened when she was small and not yet accountable. Or is this regarded as deceiving and cheating? Should she tell the one who proposes to her or not, for the sake of getting married?.
