My dd caught it at ten months, then gave it to her brothers. It was terrible, and every time my dd would touch her face she would spread it to her hands and then everywhere, it was crazy. I have a friend who lived in a community and she said at one point every kid and every adult had it, they all spent weeks trying every single remedy and treatment they could find in the end the went and got one little tube of cream from the GP (as I did too in the end) and within a couple of days everyone’s impetigo had gone1 Same with us. It spreads terrribly and is just one of those horridly contagious things. I’d be more worried about having the impetigo for so long and picking at the scabs and causing skin damage that way to be honest. The GP cream is actually very quick, brief, leaves no scarring and you litterally use such a tiny bit for only a short amount of time. I would never normally suggest going to the Gp for anything - except impetigo!!!!
