Chickenpox is caused by an infection with the varicella-zoster virus and is highly contagious. The symptoms of chickenpox mainly include fever and rash. The fever presents as a low-grade fever, possibly accompanied by chills, headache, fatigue, sore throat, and loss of appetite. These symptoms last for one to two days, followed by the appearance of a rash. The rash first appears on the trunk, then on the head and face, and is relatively less common on the limbs. It begins as red maculopapular rash and turns into vesicular rash within a few hours. The chickenpox rash appears in batches, and maculopapules, vesicles, and crusts can be seen in the same area. Chickenpox is a self-limiting disease that can be cured in about ten days. Patients should be isolated until all the vesicles have crusted over. Early in the course of the disease, antiviral treatment with acyclovir can be used. It is important to keep the skin clean and avoid scratching the vesicles to prevent infection.
