Question: where do the mites come from that cause scabies

title: Scabies
text: Scabies is caused by infection with the female mite Sarcoptes scabiei var . hominis . The mites burrow into the skin to live and deposit eggs . The symptoms of scabies are due to an allergic reaction to the mites . Often , only between 10 and 15 mites are involved in an infection . Scabies is most often spread during a relatively long period of direct skin contact with an infected person ( at least 10 minutes ) such as that which may occur during sex . Spread of disease may occur even if the person has not developed symptoms yet . Crowded living conditions , such as those found in child - care facilities , group homes , and prisons , increase the risk of spread . Areas with a lack of access to water also have higher rates of disease . Crusted scabies is a more severe form of the disease . It typically only occurs in those with a poor immune system and people may have millions of mites , making them much more contagious . In these cases , spread of infection may occur during brief contact or by contaminated objects . The mite is very small and usually not directly visible . Diagnosis is based on the signs and symptoms .
