Overview

Impetigo
Impetigo is a common and highly contagious bacterial infection of the skin. It usually causes red sores or blisters that break open and form a characteristic yellowish or honey-colored crust. It is particularly common among young children and can spread easily through direct contact. Impetigo most often affects exposed areas such as the face, hands, and limbs. There are two common forms: nonbullous impetigo, which produces crusted sores, and bullous impetigo, which produces larger fluid-filled blisters. Scratching can spread the infection to nearby skin or to other people.
Anal Fistula
An anal fistula is an abnormal tunnel that develops between the inside of the anus or rectum and the skin near the anus. It often develops after an infection or abscess in an anal gland. Symptoms may include persistent drainage, pain, swelling, irritation, or recurrent abscesses around the anus.

Diagnosis

Impetigo
Impetigo is usually diagnosed by examining the characteristic sores and crusts. Laboratory testing is not always necessary, but a sample from an infected area may be cultured when the diagnosis is uncertain, treatment has failed, or antibiotic resistance is suspected. A clinician generally recognizes impetigo from the typical appearance of the lesions and their rapid spread. Bacterial culture can identify the organism when infection is recurrent, severe, atypical, or not responding to treatment. Examination can also distinguish impetigo from conditions such as herpes infections, dermatitis, or fungal disease.
Anal Fistula
An anal fistula is diagnosed through a medical history and examination of the anus and surrounding skin. The healthcare professional may look for an external opening, drainage, swelling, or tenderness. A digital rectal examination may help identify the tract. Imaging such as MRI or ultrasound may be used when the fistula is complex, recurrent, or difficult to identify during examination.

Prevention

Impetigo
Good hand and skin hygiene can reduce the spread of impetigo. Cuts, insect bites, and other skin injuries should be cleaned and covered. Avoiding close contact with infected lesions and not sharing towels, clothing, or personal items can help prevent transmission. Promptly cleaning minor skin injuries and treating underlying itchy skin conditions can reduce opportunities for bacterial infection. Hands should be washed regularly, especially after touching affected areas. During an active infection, personal towels, clothing, bedding, and other items should not be shared with others.
Anal Fistula
Preventing anal fistula mainly involves reducing the risk of anal abscesses and treating infections promptly. People with inflammatory bowel disease should follow appropriate medical treatment and monitoring. Persistent pain, swelling, drainage, or recurrent abscesses around the anus should be evaluated by a healthcare professional rather than left untreated.

Risk Factors

Impetigo
Risk factors include close contact with an infected person, crowded living conditions, warm or humid environments, poor access to hygiene facilities, and existing skin conditions that cause breaks in the skin. Children commonly spread impetigo among classmates or family members. Children, people living in crowded settings, athletes involved in close-contact activities, and individuals with skin injuries or chronic skin conditions may have greater exposure or susceptibility. Poor hygiene and sharing personal items can facilitate transmission. Previous impetigo does not provide reliable lifelong protection against reinfection.
Anal Fistula
Risk factors include a previous anal abscess, inflammatory bowel disease such as Crohn disease, recurrent infections in the anal region, previous anal or rectal surgery, and conditions that interfere with normal healing or immunity. A history of an anal fistula also increases the likelihood of recurrence.
