Avoiding skin to skin contact with someone who has scabies is the main way to prevent getting it.
This can be difficult, however, since someone can have scabies for 1 to 2 months before showing symptoms.
Also avoiding contact with clothing, bedding, towels, etc. used by someone who has scabies can help prevent its transmission.
You can clean these items by washing and drying them using the hot settings. Or you can store them in a closed plastic bag for about a week.
If you are concerned you have scabies and need help to identify a scabies rash, it’s best to consult with a medical professional to get a proper medical diagnosis and to determine any appropriate treatment.
