Scabies is a contagious human skin infestation by the tiny (0.2–0.45 mm) mite Sarcoptes scabiei, variety hominis. The word is from Latin: scabere, lit. 'to scratch'. The most common symptoms are severe itchiness and a pimple-like rash. Occasionally, tiny burrows may appear on the skin. In a first-ever infection, the infected person usually develops symptoms within two to six weeks. During a second infection, symptoms may begin within 24 hours. These symptoms can be present across most of the body or just certain areas such as the wrists, between fingers, or along the waistline. The head may be affected, but this is typically only in young children. The itch is often worse at night. Scratching may cause skin breakdown and an additional bacterial infection in the skin.
Acrodermatitis /ac·ro·der·ma·ti·tis/ is a childhood form of dermatitis selectively affecting the hands and feet and may be accompanied by mild symptoms of fever and malaise. It may also be associated with hepatitis B and other viral infections. The lesions appear as small coppery-red, flat-topped firm papules that appear in crops and sometimes in long linear strings, often symmetric. It is a diffuse chronic skin disease usually confined to the limbs, seen mainly in women in Northern, Central, and Eastern Europe, and characterized initially by an erythematous, oedematous, pruritic phase followed by sclerosis and atrophy. It is caused by infection with Borrelia burgdorferi.
Neonatal herpes simplex, or simply neonatal herpes, is a herpes infection in a newborn baby caused by the herpes simplex virus (HSV), mostly as a result of vertical transmission of the HSV from an affected mother to her baby. Types include skin, eye, and mouth herpes (SEM), disseminated herpes (DIS), and central nervous system herpes (CNS). Depending on the type, symptoms vary from a fever to small blisters, irritability, low body temperature, lethargy, breathing difficulty, and a large abdomen due to ascites or large liver. There may be red streaming eyes or no symptoms.
Neonatal pustular eruptions are a group of disorders characterized by various forms of pustulosis seen in the first four weeks of life.
