Top 7 Parasitic Skin Diseases In The World [Infographic]

Skin diseases caused by parasites are one of the worst things that can occur to anyone. Here, we list down the Top 7 Human Parasitic Skin Diseases in the World, visualized in an infographic.

Top 7 Parasitic Skin Diseases in the World

Here is the text version of the infographic above:

  • Scabies – a contagious skin infection caused by the mite Sarcoptes scabiei. The scabies mite burrows a tunnel of up to 4 mm into the superficial layer of the epidermis, where eggs are laid. The eggs hatch and reach the stage of nymph and subsequently become an adult male or female mite. Female mites live up to 6 weeks and lay up to 50 eggs.
  • Lice – Lice are tiny insects that live on humans and feed on blood. When a large number of lice live and multiply on a person, it is called an infestation. Head, pubic, body Lice are the most common kinds of lice that live in humans. Lice spread easily from one person to another through close contact or through shared clothing or personal items (such as hats or hairbrushes). A louse cannot jump or fly.
  • Cutaneous larva migrans – This dermatosis results from the accidental penetration of the human skin by parasitic larvae from domestic canine, bovine and feline hosts. A close contact with human skin allows the infective larvae to burrow into the epidermis and cause clinical disease.
  • Leishmaniasis – Leishmania parasites are protozoan organisms transmitted to humans and other vertebrates by the bite of female sandflies of the genera Phlebotomus or Lutzomya. Most Leishmania spp. can cause skin or mucocutaneous disease, but a few of them affect internal organs as well. It is estimated that 12 million individuals are infected by Leishmania in 88 countries occur every year (WHO 2006).
  • Tungiasis – Tungiasis is a localized skin disease commonly affecting one foot and caused by the burrowing flea Tunga penetrans. This is also known as chigoe infestation, jigger, sandflea, chigoe and puce chique. Tungiasis causes skin inflammation, severe pain, itching, and a lesion at the site of infection that is characterized by a black dot at the center of a swollen red lesion.
  • Myiasis – Several dipteran species in larval stages (maggots) are capable of colonizing the human skin. The infestation mechanism involves direct deposition of eggs, contamination by soil or dirty clothes, other insects acting as vectors, or else actual penetration of larvae into the skin.
  • Ticks – Ticks are cosmopolitan ectoparasites capable of transmitting severe viral, rickettsial, bacterial and parasitic diseases. The transmission of infectious agents takes place at the time of taking a blood meal from a human host that becomes infested accidentally.
