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.
Pyelonephritis
Pyelonephritis is a kidney infection that usually begins as an infection in the bladder or lower urinary tract and then spreads upward to one or both kidneys. It commonly causes fever, chills, painful or frequent urination, and pain in the back, side, or groin. Nausea, vomiting, and changes in urine may also occur.

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.
Pyelonephritis
Diagnosis of pyelonephritis involves medical history, physical examination, and laboratory testing. Urinalysis can detect blood and white blood cells in the urine, while urine culture can identify bacteria and help guide antibiotic treatment. Blood tests may assess infection and kidney function. Ultrasound, CT, MRI, or other imaging may be used when obstruction, complications, or another cause is suspected.

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.
Pyelonephritis
Prompt treatment of bladder infections can help reduce the chance of infection spreading to the kidneys. Drink adequate fluids unless a healthcare professional has advised otherwise, and seek medical care for symptoms such as fever, back or side pain, or painful urination. People with recurrent infections, urinary blockage, reflux, diabetes, or other risk factors should follow individualized medical advice.

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.
Pyelonephritis
Risk is higher in females, during pregnancy, and in people with a current or recent bladder infection. Urinary tract blockage from a kidney stone or enlarged prostate, vesicoureteral reflux, diabetes, and weakened immunity can increase risk. Structural or functional problems affecting normal urinary flow can also make kidney infections more likely.
