Varicella is a highly contagious disease caused by the initial infection with varicella zoster virus. The disease results in a characteristic skin rash that forms small, itchy blisters, which eventually scab over. It usually starts on the chest, back, and face. It then spreads to the rest of the body. The rash and other symptoms, such as fever, tiredness, and headaches, usually last five to seven days. Complications may occasionally include pneumonia, inflammation of the brain, and bacterial skin infections. The disease is usually more severe in adults than in children.
Chickenpox is an airborne disease which spreads easily from one person to the next through the coughs and sneezes of an infected person. The incubation period is 10 to 21 days, after which the characteristic rash appears. It may be spread from one to two days before the rash appears until all lesions have crusted over. It may also spread through contact with the blisters. People usually only get chickenpox once. Although reinfections by the virus occur, these reinfections usually do not cause any symptoms.
Since its introduction in 1995, the varicella vaccine has resulted in a decrease in the number of cases and complications from the disease. Routine immunization of children is recommended in many countries. Since immunization the number of infections in the United States has decreased nearly 90%. For those at increased risk of complications, antiviral medication such as aciclovir are recommended.
○ Treatment If symptoms are not serious, over-the-counter antihistamines can be taken and monitored. However, if symptoms are severe, prescribing antiviral drugs may be required.

A boy is presenting with the characteristic blisters of chickenpox.
This is a typical chicken pox lesion. It is characterized by a mixture of blisters, erythema, and scabs occurring simultaneously. It can happen even if you have been vaccinated. If you have been vaccinated, symptoms may be mild. There can be rapid improvement with antiviral treatment.
If you have been vaccinated against chickenpox, the symptoms may be mild and it may be difficult to diagnose the disease.
A single blister is observed; however, as shown in the photo, it is characteristic that erythema is also present around it.
Chickenpox or varicella is a contagious disease caused by the varicella-zoster virus (VZV). The virus is responsible for chickenpox (usually primary infection in non-immune hosts) and herpes zoster or shingles (following reactivation of latent infection). Chickenpox results in a skin rash that forms small, itchy blisters, which scabs over. It typically starts on the chest, back, and face then spreads. It is accompanied by fever, fatigue, pharyngitis, and headaches which usually last five to seven days. Complications include pneumonia, brain inflammation, and bacterial skin infections. The disease is more severe in adults than in children. Symptoms begin ten to 21 days after exposure, but the average incubation period is about two weeks.
