You probably won’t notice anything to begin with, but then soon the rest of your family will complain of itching, especially around the hands and fingers and around the waist and elbows. Any rashes that develop will always be bilateral, that is in the same places on both sides of the body. So for instance there will be a rash on both knees or elbows not just on one.
Men and boys develop nodules on their scrotum and penis, these are absolutely indicative of scabies as no other disease has nodules in these places, they are also extremely itchy.
