Most bugs that burrow in to the human skin are quite small and they can do so without the host noticing. They usually cause rashes, paleness, itchiness, redness and even swelling of the skin. One of those bugs has to be jiggers. Jiggers burrow in to human skin and cause so much irritation.
Apart from jiggers, we have ticks which burrow in to the skin to suck blood from a human host. If not noticed early, they can sink their head as deep as they can to reach blood vessels. They usually grow bigger as they continue feeding on your blood.
Other than bugs, there are other parasites that burrow in to human skin. Itch mites burrow in to the skin and lay eggs under the top layer of your skin. They cause a condition called scabies. Scabies is not only highly contagious, it can be easily transmitted through sharing clothes, sexual intercourse and even by holding hands! These mites are microscopic parasites that cannot be seen by the naked human eye.
Hookworms are other parasites that live in grass and mostly penetrate the skin through legs. When barefoot, the parasite hooks itself to the skin then penetrates to the vascular system. They are common with animals and can also be transferred through eating uncooked meat.
Skin parasites are not only irritating; they can cause you so much embarrassment. Since these bugs and parasites tend to be very small in size, one should check their skin regularly and especially if they have an itchy sensation.
Bugs and parasites that burrow in to human skin can cause health related problems if they are not done away with as soon as possible. All bugs are not usually caused by dirt; some of them are picked from pets and the environment.
