In the early stages, human ringworm may resemble mosquito bites.

In general, during the early stages of ringworm infection in humans, skin lesions resembling mosquito bites may be caused by factors such as fungal carriage on pet cats, low immunity, fleas, allergies, or cat ringworm (dermatophytosis). Detailed explanations are as follows:

1. Fungal carriage on pet cats

If a cat carries fungi, direct contact with the animal may lead to fungal infection of the skin, triggering ringworm and causing red rashes similar to mosquito bites. Patients can apply antifungal creams such as terbinafine hydrochloride cream or miconazole nitrate cream under medical guidance. Additionally, maintaining local hygiene and avoiding scratching the affected area is important.

2. Low immunity

Prolonged malnutrition may weaken the immune system, making individuals more susceptible to fungal infections and increasing the risk of developing ringworm, which may present as mosquito bite-like rashes. Patients are advised to engage in moderate physical exercise to boost their immune resistance, aiding recovery. When necessary, oral antifungal medications such as itraconazole capsules or fluconazole capsules may be taken as directed by a physician.

3. Fleas

Red bumps resembling mosquito bites after owning a cat may result from flea bites. Flea bites often look similar to mosquito bites. It is essential to bathe the cat and administer flea treatment, followed by applying antibacterial and anti-inflammatory ointments to the affected areas on the human body. Medications such as calamine lotion or cetirizine hydrochloride tablets may be used under medical supervision.

4. Allergy

The rash may be due to an allergic reaction to cat hair, resulting in lesions that resemble mosquito bites. Antihistamines such as loratadine tablets or chlorpheniramine maleate tablets should be taken as prescribed. Symptoms usually resolve gradually with proper treatment. In such cases, it is recommended to avoid keeping cats and minimize direct contact with them.

5. Cat ringworm (Dermatophytosis)

Cat ringworm is a zoonotic disease. If a person has weakened immunity and comes into contact with a cat carrying dermatophytes, they may develop ringworm. The pathogenic fungi can cause red rashes at the site of infection, accompanied by symptoms such as itching and swelling. Topical antifungal medications such as ketoconazole cream or miconazole nitrate cream can be applied under a doctor’s guidance.

If patients experience discomfort, they should seek prompt medical attention for accurate diagnosis and timely treatment to prevent disease progression.
