Varicella (Chicken Pox)
Varicella (chickenpox) is an acute, highly infectious disease caused by varicella zoster virus (VZV), a herpes virus. It is a common childhood infection. The virus is transmitted via person to person contact and airborne spread of respiratory secretions/vesicular fluid.Infected individuals infectious 1-2 days before the rash and until all lesions crusted (4 - 7 days).

- Majority of infections are symptomatic although may be very mild and unrecognised.
- Flu-like symptoms 1 - 2 days (may be absent in children).
- Characteristic rash often begins on face/scalp then spreads to trunk:
- Centripetal distribution, hands/feet usually spared - may involve eyes, mouth, intestines and lungs.
- Lesions evolve from macules - papules - vesicles - pustules - scabs in successive crops - lesions of different stages visible in same area maybe few lesions or several hundred.
- Majority of cases require no treatment.
- Antihistamines may relieve pruritus.
- Antivirals (acyclovir, valaciclovir, famciclovir) reduce duration of fever and rash if given early, may be used IV if risk of severe disease.
