I have some info about scabies which i want to share with all of us that Scabies is actually caused by Sarcoptes scabiei, which is a tiny mite with eight legs. You will not be able to detect the mite without the aid of a microscope.
The mites are generally attracted by the heat and smell generated by the human body. As soon as they gets into the skin they burrow all the way to the bottom of the skin’s surface. The next thing they do is to create tunnels, which serve as their habitat. The female mites will then lay eggs inside the skin and before long a whole colony of mites spreads all across the skin. Careful observation of the skin can actually reveal the tiny tunnels created by the mites. It takes a few weeks for the incubation period, and it is only after this that the symptoms of scabies appear on the body.
