Duration and Info about Ringworm Contagion: Essential Facts to Understand
Ringworm, a common fungal infection that causes red, itchy, and ring-shaped lesions on the skin, can be a persistent problem for both pets and humans. Despite the start of treatment, both parties can remain contagious for weeks, necessitating isolation and rigorous cleaning practices until full resolution is confirmed by a veterinarian or doctor.
In the case of pets, particularly cats and dogs, aggressive antifungal treatment can help reduce contagiousness, but they may remain contagious for about three weeks. However, quarantine is typically advised for three to six weeks until the infection is fully resolved and the animal is no longer shedding infectious spores. For dogs, isolation and thorough cleaning of the environment are crucial as ringworm spores can persist in the home for long periods, even over a year if not properly disinfected. Treatment usually involves topical antifungal creams or shampoos, plus oral antifungals for several weeks to fully clear the infection.
For humans, ringworm remains contagious at least until effective treatment has begun and lesions are healing. Generally, people remain contagious for several days to a few weeks after starting treatment. It is essential to continue hygiene measures and follow treatment duration advised by healthcare providers to prevent spreading to others. Proper handwashing, avoiding contact with infected pets or people, and cleaning contaminated surfaces reduce the risk of transmission.
Preventing ringworm involves wearing looser fitting shoes, changing underwear and socks daily, keeping the skin clean and dry, avoiding walking barefoot in showers, showering immediately after playing contact sports, washing hands after playing with a pet, seeking veterinary treatment for an infected pet, and preventing the infection from spreading by disinfecting objects that have come into contact with an infected person or animal.
Clothes, bedding, and towels should be washed in hot, soapy water. An ultraviolet shoe sanitizer or ozone cabinet can be used to disinfect shoes. People should avoid sharing personal items such as bedding, towels, clothing, accessories, hairbrushes, and makeup.
Ringworm is the same fungus that causes athlete's foot and jock itch. It spreads through direct contact with infected skin or fungal spores. Ringworm is contagious for as long as the fungi spores that cause it remain alive. After touching or treating the ringworm lesion, hands should be washed thoroughly. People with ringworm should avoid scratching or touching the ringworm lesion and avoid walking barefoot in the home.
Ringworm on areas with little to no hair may resolve in two to four weeks with treatment, while severe or hairy areas may take longer. Ringworm on the scalp requires prescription medicine such as oral antifungals and medicated shampoo. Fungal spores can live for 12 to 20 months. After touching the pet, hands should be washed with soap and water. People with athlete's foot should avoid leaving worn socks lying around.
In conclusion, while ringworm can be treated effectively, it is crucial to maintain a high level of hygiene and follow the advice of healthcare providers to prevent the spread of this contagious fungal infection.
