The typical incubation period for varicella disease is 14 to 16 days, but may last for up to 21 days. This period may be decreased in immunocompromised patients and can be increased to 28 days with the use of varicella-zoster immune globulin (VZIG).

Chickenpox can be very severe or even life-threatening to babies in the first month of life, to adolescents and adults, and to anyone who has a weak immune system. Children with chickenpox can get pneumonia (infection of the lungs) or get inflammation of the brain.

Susceptibility and resistance to smallpox (variola) Pregnant women and people who are immunocompromised are more susceptible to variant forms of smallpox. It is unclear how long the smallpox vaccine provides effective immunity, but it is unlikely to be more than 10 years.

People are usually no longer contagious within 24 hours of treatment. Even after successful treatment, the dead mites, dead eggs, and fecal material will remain in the skin for 2 to 4 weeks (until the skin grows out).

Until information is available, it is prudent to apply the same rules to varicella vaccine as are applied to MMR: a TST (i.e., PPD) may be applied before (preferably) or simultaneously with varicella vaccine. If vaccine has been given, delay the TST for at least 4 weeks.

Chickenpox is caused by the varicella-zoster virus (VZV). This virus also can cause a painful skin rash called shingles (herpes zoster) later in life. After someone has had chickenpox, the virus stays dormant (resting) in the nervous system for the rest of their life.

Symptoms like fever and sore throat last for a week or so. Hand lesions can last for two weeks, throat lesions can last for a few weeks, and foot lesions can last for several weeks, notes Dr. Vyas. “The blisters can be painful, so when you have them in your mouth, as kids do, it can hurt to swallow,” she adds.

Chickenpox is a common childhood disease. It causes an itchy, blistering rash and is easily spread to others. Until the varicella vaccine was licensed in 1995, chickenpox infection was very common. Almost everyone had been infected as a child.

It is not known how long a vaccinated person is protected against varicella. But, live vaccines in general provide long-lasting immunity. Several studies have shown that people vaccinated against varicella had antibodies for at least 10 to 20 years after vaccination.

Unlike an allergic reaction, viral rashes usually do not cause itching or pain. Viral rashes usually go away after a few days, but may last up to 2 weeks. Antibiotics are not used to treat viral rashes.

The two conditions are often confused by parents, but while chickenpox spots are water-filled blisters, molluscum are dome-shaped and pearly. And chickenpox spots normally burst and clear within days or weeks, but molluscum can linger for months or even years.

Varicella-zoster virus (VZV) causes the chickenpox infection. Most cases occur through contact with an infected person. The virus is contagious to those around you for one to two days before your blisters appear. VZV remains contagious until all blisters have crusted over.
