Gbs + and water broke on husband??

Husband and I were having sex and my water broke on him. I’m gbs + and it got in a cut of his. He has had a rash that is painful for a week now (since I went into labour). It’s a lot better now, but he was told to go to the ER by nurses, telling him it was a major health concern which he refuses to. Since his rash has gotten better and supposedly less painful, is he okay? Or could he be infected even if it seems to be going away??
