When the lesions have crusted(Ref: Nelson's 20/e p 1579-1585, Ghai 8/e p 214-215, CDC website)The period of communicability of varicella begins 1-2 days before the onset of rash and ends when all lesions are crusted, typically 4-7 days after onset of rash in immunocompetent people, longer in immunocompromised peoplePeople with varicella should be isolated until the lesions crust over.
