Reye syndrome The cause of Reye syndrome is unknown.[2] It usually begins shortly after recovery from a viral infection, such as influenza or chickenpox.[1] About 90% of cases are associated with aspirin (salicylate) use in children.[2] Inborn errors of metabolism are also a risk factor.[3] Changes on blood tests may include a high blood ammonia level, low blood sugar level, and prolonged prothrombin time.[2] Often the liver is enlarged.[2]
Herpes simplex Herpes simplex is a viral disease caused by the herpes simplex virus.[1] Infections are categorized based on the part of the body infected. Oral herpes involves the face or mouth. It may result in small blisters in groups often called cold sores or fever blisters or may just cause a sore throat.[2][5] Genital herpes, often simply known as herpes, may have minimal symptoms or form blisters that break open and result in small ulcers.[1] These typically heal over two to four weeks.[1] Tingling or shooting pains may occur before the blisters appear.[1] Herpes cycles between periods of active disease followed by periods without symptoms.[1] The first episode is often more severe and may be associated with fever, muscle pains, swollen lymph nodes and headaches.[1] Over time, episodes of active disease decrease in frequency and severity.[1] Other disorders caused by herpes simplex include: herpetic whitlow when it involves the fingers,[6] herpes of the eye,[7] herpes infection of the brain,[8] and neonatal herpes when it affects a newborn, among others.[9]
