Scabies is a parasitic infestation of the skin caused by the mite Sarcoptes scabiei. The infestation goes through several stages, but there is no specific last stage of scabies. Instead, the infestation can last for several weeks or even months if left untreated.
The stages of scabies infestation are as follows:
- Initial stage: The mite burrows into the skin and lays eggs.
- Early stage: The eggs hatch and the larvae move to the surface of the skin.
- Mid-stage: The larvae mature into adult mites and continue to burrow into the skin.
- Late stage: The infestation spreads and can cause intense itching, skin rash, and secondary infections.
Treatment for scabies typically involves the use of topical medications, such as permethrin or ivermectin, which kill the mites and their eggs. It is important to seek treatment promptly to prevent the infestation from progressing to more severe stages.
