We were exploring some of the potential underlying medical causes of unexplained rashes in our last post. Here are 15 more conditions that can cause a rash:

  1. Juvenile rheumatoid arthritis can cause symptoms such as unexplained pain, fever and rash in children. If your child has persistent fevers and skin problems accompanied with swelling or abnormal pain, have him or her checked out soon.
  2. Hookworm infection can cause visible symptoms as well as internal ones. The rash that often accompanies a hookworm infection is a long, spindly line rash that may also have some spots appearing with it.
  3. Sexually transmitted disease – Many different types of STDs can cause different types of rashes and other skin issues such as warts, boils or welts. Some STDs like gonorrhea often cause rashes.
  4. Kawasaki disease causes the blood vessels to become enflamed which can lead to a bright red tongue, a rash on the body (sometimes around the genital area) as well as red lips and swelling of the lymph nodes.
  5. Addison’s disease can cause darkening of the skin and a rash-like appearance.
  6. Mononucleosis can cause a spotty, bright red rash all over the body or on select parts of it.
  7. Measles is a highly infectious virus that can cause a high fever, cough and rash all over the body as well as inside the mouth.
  8. Phenylketonuria is an inherited disorder caused by a build up of amino acids in the blood. It can cause a light red patchy rash, especially on the face. It can also cause such serious symptoms as seizures and delayed mental development if it isn’t treated in a timely manner.
  9. Eczema (dermatitis) causes patches of skin to become inflamed, itchy, dry, red and cracked. This can appear rash-like.
  10. Heat rash is a result of the sweat ducts become blocked and don’t allow the sweat to reach the skin’s surface, causing inflammation. It causes small red bumps to form on the skin which may progress to blisters if the heat rash is severe.
  11. Rubella, also known as the German measles, is a virus that causes a fine red rash to form over the body accompanied by fever and other problematic symptoms.
  12. Scabies is an infestation of tiny mites called sarcoptes scabiei that burrow into the outer layers of the skin, causing skin inflammation and an intensely itchy hive-like rash.
  13. Psoriasis is an autoimmune skin condition that starts as patches of red bumps which often morph into scaly red skin plaques. These plaques often happen on the elbows, knees, back or trunk but can happen anywhere on the body including the face or genitals.
  14. Rosacea is a common skin condition that causes inflammatory red facial flushing and acne-like bumps.
  15. Rocky Mountain spotted fever is a condition caused by a tickborne bacteria that can potentially be fatal to humans. It can cause such symptoms as severe headache, fever, vomiting and a red rash that can span the body.
