Scabies is a common skin problem caused by mites, which look like small ticks. These mites burrow into the skin and cause an itchy rash with small red bumps and blisters. Sometimes, the skin can also become infected, although there are no long-term effects of scabies.
Scabies is highly contagious and is spread by close contact. If untreated, it can last indefinitely. Scabies is not caused by poor hygiene.
