The Mite:


The mite that spreads the scabies is the first major cause of scabies being infested in any individual. The female mite burrows deep inside the skin of the humans and after a certain number of days starts dropping larvae which then multiply and becomes extremely difficult to get the infection away. These larvae multiply that causes extreme rashes as the immune system responds accordingly which can also cause inflammation. The adult form of the larvae is able to mate and further proceeds with eating the human host while resting inside the skin. A pregnant female mite may travel through close human contact with another person, where she can then start the whole infectious process all over again


Crowded Conditions:


Scabies outbreak is mostly seen in the kids, more than adults. Also, they are mostly to be found in places that are crowded. Areas like daily health care, nurseries are major spots where you might find the mite causing the infestation. This is because they are not well kept or they aren’t cleaned on a regular basis.



Close Contact:


Any close contact with those individuals can lead to an infestation of scabies.

Skin contacts are the major source, even sexual partners can face the condition, and therefore a major cause of suffering from scabies.
