Chickenpox, also known as varicella, is a highly contagious virus that can be transmitted through the air. Although most common in children, it sometimes affects adults too. A vaccine to protect against this condition was introduced in the United States in 1995, and two doses of the vaccine provide ninety percent protection against the virus. Doctors recommend vaccination for anyone who has not had chickenpox; individuals who have had the condition normally have lifelong immunity and do not need the vaccine. To diagnose chickenpox, doctors will examine the skin for any rashes, and blood tests or skin samples might be used to confirm the diagnosis. Antihistamines can reduce itching associated with the rash, and antiviral medicines such as acyclovir may be prescribed to patients at a high risk of complications from the virus.
Some of the major symptoms associated with chickenpox are outlined below.
Iconic Itchy Rash
An iconic itchy rash is often the major symptom produced with the chickenpox. The rash generally begins on the chest, back, and face, eventually spreading across the entire body. Occasionally, the rash may also be present in the mouth. At first, small raised pink or red bumps appear, and these form blisters that break open in about twenty-four hours. After the blisters break, scabs form over them. Patients with varicella may have between 250 to five hundred blisters, and the patient is considered contagious until all of the blisters have formed scabs. For most patients, the process of scab formation takes about a week. To reduce the extreme itchiness of the chickenpox rash, it may be helpful to put calamine lotion on the blisters, and a colloidal oatmeal bath is often particularly soothing. If blisters occur in the mouth, it is beneficial to follow a bland diet of soft foods so eating is easier.
