Chickenpox (varicella) is a highly contagious disease caused by the varicella- zoster virus. Signs and Symptoms: The disease starts with cold-like symptoms.
Persons with varicella are considered infectious from 1 to 2 days before the rash appears and until all lesions are crusted over. Cases should be considered part of an outbreak if they occur within at least one incubation period 10—21 days of the previous case-patient, and surveillance should continue through two full incubation periods 42 days after the rash onset of the last identified case-patient to ensure that the outbreak has ended.
Patients with zoster have been found to be contagious to those who have no immunity to VZV. The route of transmission is via direct contact of the skin or exposure to dressings or clothing soiled with blister fluid from such individuals.
Therefore, HZ is considered far less contagious than its varicella counterpart because the virus is believed to be localized to the skin and does not involve the respiratory tract. They recommend the covering of HZ lesions as a means of preventing nosocomial spread and do not recommend the isolation of all affected patients. Studies have now shown that airborne transmission may occur in both varicella and zoster.
Strategies for managing zoster patients may have to incorporate the same precautions of airborne transmission as with varicella patients to reduce the risk for transmission.
