Overview
Primary varicella presents with pruritic macules, papules, vesicles, pustules, and crusts, usually on the back, chest, face, and abdomen. Reactivation of the virus can present as shingles. Common complications of chickenpox are, bacterial infections of the skin and soft tissues in children and pneumonia in adults. Chickenpox is rarely fatal. Pregnant women and immunocompromised patients are at a higher risk of developing varicella pneumonia.
Natural History
If left untreated, in healthy children varicella manifestations develop within 15 days post exposure and typically present as: [1]
- Generalized vesicular rash develops within 24 hours
- Fever
- Malaise
- Pharyngitis
- Loss of appetite
- Infection in adults can cause VZV pneumonia
Complications
The disease is usually mild, although serious complications sometimes occur. Two of the most common complications are bacterial infections of the skin and soft tissues in children and pneumonia in adults.[2][3][1]
Complications in Immunocompetent
Some of the severe complications associated with chickenpox include:[2][4][5][3]
- Toxic shock syndrome
- Viral pneumonia
- Zoster paresis[6]
- Neuralgia—PHN[6]
- VZV meningoencephalitis[6]
- VZV vasculopathy
- VZV and giant cell arteritis[6]
- VZV-induced stromal keratitis [6]
- Necrotizing fasciitis
- Septicemia
- Osteomyelitis
- Bacterial pneumonia
- Cerebellar ataxia
- Encephalitis
- Hemorrhagic conditions.
- Septic arthritis
Complications in Immunocompromised
- Hemorrhagic complications
- Febrile purpura
- Malignant chickenpox with purpura (mortality rate of greater than 70%)
- Aanaphylactoid purpura
Prognosis
- Chickenpox is rarely fatal except if the patient develops varicella pneumonia.
- Prognosis in the immunocompromised is poor.
- Varicella zoster virus remains dormant in nerves which can be reactivated later resulting in shingles. It is most commonly seen in the immunocompromised and the elderly.
