It is transmitted via respiratory secretions and contact with chickenpox blister contents. It presents with a vesicular skin rash, usually associated with fever, headache, and myalgias. The pruritic fluid-filled vesicles occur 10-21 days after exposure and last for 3-4 days. An additional 3-4 days of malaise follows before the affected individual feels better. An individual is contagious 1-2 days prior to the appearance of the blisters until all blisters are crusted over. Generally, healthy individuals recover without complications. **Genetic basis** No **Non-human condition** No **Rare disease** No **Listing at source** Listed **Condition name** Chickenpox **Therapeutic area** Dermatology ### Alternative names (6) -
