After the skin becomes infected and ulcerates due to insect bites, comprehensive treatment measures should be taken:
1. **Cleaning and disinfection**: Clean the bite area with soap and water or warm water to remove dirt, then disinfect the site locally with povidone-iodine to prevent worsening of the infection.
2. **Topical medications**: Under a doctor's guidance, apply antibiotic ointments such as erythromycin ointment or mupirocin ointment to control the infection. If itching is severe, antihistamine creams such as hydrocortisone butyrate cream may be used to relieve symptoms.
3. **Oral medications**: If the infection is severe or accompanied by systemic allergic symptoms, oral antibiotics such as cephalosporins and antiallergic drugs such as loratadine should be taken as prescribed.
4. **Daily care**: Keep the affected area clean and dry, and avoid scratching or contaminating the wound to prevent worsening of symptoms.
5. **Seek medical advice**: If symptoms persist or worsen, seek timely medical consultation and follow the doctor's instructions for further treatment.
Specific treatment should be based on individual conditions and medical advice.
