What does ringworm look like in cats and humans? - briefly
Ringworm appears as circular patches of hair loss on cats, often with scaling or crusting. In humans, it manifests as red, raised, scaly patches that may blister or ooze, usually forming ring-shaped patterns.

Ringworm, also known as dermatophytosis, is a fungal infection that affects both cats and humans. While it can manifest differently in each species, there are several common characteristics that help identify this condition.
In cats, ringworm typically appears as circular or irregular patches of hair loss on the head, ears, legs, or tail. The skin underneath these patches may appear red, scaly, or crusty. In some cases, the affected areas may be itchy, causing the cat to scratch excessively. Additionally, cats with ringworm might exhibit behavioral changes such as increased irritability or restlessness due to discomfort. It's important to note that not all cats will show symptoms, making diagnosis more challenging in some instances.
In humans, ringworm presents as a red, raised, scaly patch on the skin with sharp edges. The lesion often has a distinctive ring-like appearance, giving the infection its name. Human ringworm can occur anywhere on the body but is most commonly found on the scalp, face, neck, or arms. Itching is a common symptom, and the affected area may become inflamed or painful if not treated promptly. In severe cases, the infection can spread to the nails, causing them to thicken, discolor, or even crumble.
Diagnosing ringworm in both cats and humans involves examining skin scrapings or hair samples under a microscope to detect the presence of fungal spores. In some instances, a Wood's lamp (which emits ultraviolet light) may be used to illuminate infected areas, as many types of ringworm fluoresce under this light. However, this method is not foolproof and should be combined with other diagnostic tools for accurate results.
Treatment for ringworm varies depending on the species affected. In cats, antifungal medications such as itraconazole or terbinafine are commonly prescribed, along with topical creams or shampoos to help manage symptoms and prevent spread. Quarantine measures are also essential to contain the infection and protect other pets in the household. For humans, over-the-counter antifungal creams like clotrimazole or terbinafine can be effective for mild cases. More severe infections may require oral antifungal medications prescribed by a healthcare provider.
Preventing the spread of ringworm involves maintaining good hygiene practices, such as regular handwashing and avoiding contact with infected animals or surfaces. In multi-pet households, it's crucial to isolate infected cats and regularly clean and disinfect shared spaces to minimize the risk of transmission. Early diagnosis and treatment are key to controlling ringworm outbreaks and preventing further complications.
