Ringworm in Humans: Symptoms, Causes, Diagnosis, Prevention and Treatment


  • Ringworm can present in a variety of ways, depending on the location of the infection. Common symptoms include:
  • Itchy, red, scaly patches on the skin
  • Ring-shaped rash
  • Small, raised bumps on the skin
  • Crusty or blistery lesions
  • Scalp itching and hair loss
  • Brittle or thickened nails


Ringworm is caused by a group of fungi called dermatophytes, which thrive in warm, moist environments. The infection is spread through direct contact with an infected person or animal, or by coming into contact with contaminated surfaces or objects. Risk factors for ringworm include:

  • Being in close contact with infected individuals or animals
  • Having a weakened immune system
  • Participating in activities that involve skin-to-skin contact, such as sports
  • Having a history of skin conditions, such as eczema or athlete’s foot


Risk factors

  • Living in warm and humid areas
  • Excessive sweating
  • Wearing tight and non-breathable clothes
  • Having a close contact with an infected person or animal
  • Having a compromised immune system
  • Having a skin condition such as eczema or atopic dermatitis



Ringworm is typically diagnosed by a physical examination of the affected area. Your doctor may also take a skin scraping or nail clipping to be examined under a microscope. In some cases, a fungal culture may also be taken to confirm the diagnosis.



Ringworm can be treated with over-the-counter or prescription anti-fungal medications. Topical creams and ointments are often used for skin infections, while oral anti-fungal medications may be prescribed for more severe or widespread infections. In some cases, a combination of topical and oral medications may be used. It is also important to keep the affected area clean and dry, and to avoid sharing personal items such as towels or combs.



The best way to prevent ringworm is to practice good hygiene, such as keeping the skin clean and dry, and avoiding close contact with infected individuals or animals. Wearing breathable clothing and avoiding tight-fitting clothing can also help reduce the risk of infection. It is also important to avoid sharing personal items, such as towels or combs, with others.


Ringworm is a common fungal infection that can be treated with anti-fungal medications. It is important to take steps to prevent the spread of the infection, and to seek treatment as soon as symptoms appear. If you suspect that you or a loved one has ringworm, it is important to consult with a healthcare provider for proper diagnosis and treatment.
