If it is about scabies infection, it starts with the arrival of the scabies mites, Sarcoptes scabiei. As soon as the mite comes into contact with a suitable host, it attach to the host with its teeth. Actually, these mites possess special scissor-like apparatus on the front legs, which they use to enter your skin. From that particular point, the mites continue to burrow under the skin. Later, they lay eggs and feed on blood from the host. With the passage of time, when the eggs hatch, the larvae continue to spread out under the skin. Generally, eggs hatch in 3 - 10 days, and then grow into bigger mites.
What causes scabies?
As stated earlier, it is the itch mite or Sarcoptes scabiei, which are tiny anthropoids living in the burrows (formed by them) under the skin of humans and animals. These mites are equally parasitic to wild animals and domesticated ones. It is worth noticing that different species of itch mites may be inclined to inhabit certain areas, but these tend to produce the similar disturbing symptoms.
It Infests Humans and Animals!
If a human or animal becomes infested with scabies, this skin condition is referred to mange. Well, scabies cause severe itching. People tend to scratch their skin and when done in excess it can cause serious damage. Now at this particular point, things become fairly easy for the bacterial and fungal infections to set in. And here it is where the story starts for complicate recovery.
In humans, these infestations start in the wrists and hands. So, no matter where you live in the world, if you wish to stay away from scabies, it is best to avoid skin-to-skin contact with the infested person. Moreover, it is vital to know that scabies mites can survive off their host too. Hence, these can be found easily on the towel, attires, bedding, chair or the shoes used by scabies infested person. Now when a healthy person comes into contact any infected stuff, i.e. anything used by the diseased, there are good chances of spreading mites.
