is a contagious disease, if a person in the family having scabies if proper care is not taken can spread to whole family.
common sites are inter digital spaces of hands and foot,inner site of thighs,armpits and on the back.
what you have to do is keep your under garments clean and separate,
Have individual towel everybody,
Take bath with Neko soap,
keep the parts mainly inter digital spaces dry,
Apply Ascabiol lotion all over body at night and take bath in the morning.Simply apply smoothly and not rubbing.
Before applying brush the affected parts with towel so that minute eruptions will open so that lotion can penetrate inside the parts.
For itching you can take anti histamines
I think this will satisfy your query,for more detail you feel free to ask.
Ok and bye.
