Scabies is an easily spread skin disease caused by a very small type of mite.
Scabies is found among people of all groups and ages around the world.
Outbreaks of scabies are more common in nursing homes, nursing facilities, college dorms, and child care centers.
The mites that cause scabies burrow into the skin and lay their eggs. This forms a burrow that looks like a pencil mark. Eggs hatch in 21 days. The itchy rash is an allergic response to the mite.
Pets and animals cannot spread human scabies. It is also not very likely for scabies to be spread by:
Mites may be more widespread on a baby's skin, causing pimples over the trunk, or small blisters over the palms and soles.
The doctor will examine your skin for signs of scabies. The doctor will look at scrapings taken from a burrow to look for the mites. A skin biopsy can also be done.
MEDICINES FROM YOUR HEALTH CARE PROVIDER
The whole family or sexual partners of infected people should be treated, even if they do not have symptoms.
Creams prescribed by your health care provider are needed to treat scabies.
Apply the medicine all over your body. Creams may be used as a one-time treatment tor they may be repeated in 1 week.
For hard to treat cases, your health care provider may also prescribe a pill known as Ivermectin.
Itching may continue for 2 weeks or more after treatment begins. It will disappear if you follow your health care provider's treatment plan.
Most cases of scabies can be cured without any long-term problems. A severe case with a lot of scaling or crusting may be a sign that the person has a disease such as HIV.
Intense scratching can cause a secondary skin infection, such as impetigo.
