Does anyone know if you are more likely to get scabies because your young or old? Because I do not have scabies yet I am living with and enfant and my grandma who have had it for a month, I have treated the both of them and I am still to be infected. Do you think it is because of their ages and my body can fight against scabies?

Yes indeed! People younger and older or with medical conditions will always be more suceptable to scabies because of their immune system like said above. You can do things like implement vitamins and have a better diet to help you combat scabies from the inside out. I think scabies like when you eat starches and sugares they become more active or your body is more allergic. I noticed once I cleaned up my diet the itching kinda subsided alot.
