What should be done if a child scratches a mosquito bite until it breaks the skin?
My son has an allergic constitution and was bitten by insects. After being bitten, the area becomes increasingly swollen, and after scratching, it oozes pus. I would like to know what to do if a child scratches a mosquito bite until it breaks open.

First, perform local disinfection if a child's skin is broken due to scratching after a mosquito bite. Use a cotton swab dipped in water to gently clean away any blood, then apply iodophor and alcohol to achieve local disinfection. Secondly, apply lincomycin lidocaine gel in a timely manner. Lincomycin lidocaine gel has effects of relieving itching and pain and preventing infection; however, it is contraindicated for infants under one month old. Lidocaine is an anesthetic that provides significant pain and itch relief, while lincomycin is an antibiotic that can effectively prevent secondary bacterial infections in children.
