While scabies are a common skin condition, lice are a more serious problem.
You can have scabies but not lice. In these cases, the rash is triggered by something like a scabies-infested pillow case or clothing.
In addition, lice spread more easily than scabies. They can live up to a month without feeding, so they spread quickly.
Both scabies and lice are transmitted through close contact, so it’s important to be careful about how you share clothing or towels.
Symptoms of scabies and lice
Both lice and scabies have similar symptoms. They can be confused for one another, especially if there are no symptoms.
If you have lice, you’ll notice an itchy rash on your scalp, back, or both. It’s usually found in a small area on the scalp. Your scalp may also be itchy and red.
If you have scabies, your symptoms will differ.
You’ll notice red, itchy rashes around your hairline, face, and neck. The rash may be larger if you have more than one person in your home with lice.
You may also notice a small, itchy spot on your clothing, especially around your waist or under your armpits.
Scabies and lice are both transmitted by close contact, so it’s important to avoid sharing clothing or towels.
