I have attached some pictures, kindly check them. My brother who is 19, keeps getting these rashes, some of which look like ringworm and others are kind of small, in groups. They are near the armpits and near the area behind/sides of the knees which is similar to that of an armpit. We can't risk going outside due to covid and the nearest dermatologist is pretty far away. Please help. He bathes two times daily so I do not know if this is due to poor hygiene, or if these are just ringworms but the smaller ones do not look like ringworm. Help please. Thanks in advance.
