The typical presentation of chickenpox in adults is a rapid onset, with fever, headache, general malaise, nausea, vomiting, sore throat, and other discomforts, and may be combined with liver damage and lung inflammation. The rash usually appears within one day of onset, starting from the head, face, chest and back and gradually spreading to the extremities. The rash starts as a maculopapular rash, then rapidly turns into a herpetic rash and then crusts. Some patients who have been vaccinated may also develop chickenpox, but may not present typically. For example, the rash is less frequent, the fever is lower, or other accompanying symptoms are less frequent. In adults, a few patients may develop chickenpox pneumonia with cough and sputum. If the patient is weak, the body temperature will be higher and should be controlled. If the liver function is abnormal, liver protection treatment is needed.
