Red and swollen genitals in infants may be caused by folliculitis, requiring localized application of ichthammol ointment and intravenous administration of a large amount of antibiotics for treatment. It is important to avoid spicy, alcohol, and other irritating foods in daily life and to enhance nutrition.

A one-year and eleven-month-old baby began to have a fever in the evening of November 5th, with a temperature of 38.8 degrees measured before bedtime, and received fever-reducing medication. On the evening of the 6th, redness appeared in the lower part of the child’s genitals, and the child cried out in pain. On the morning of the 7th, the temperature was normal, but a urine routine test showed normal results, while a blood routine test indicated a bacterial infection. The doctor pointed out that pharyngitis was the main cause, but the reason for the genital swelling was unclear.
