How long is chickenpox contagious?

Answer 1

Chickenpox symptoms start between ten and 21 days after exposure, but usually around two weeks. The disease is most contagious a day before the rash appears and up to seven days after, or until the rash forms scabs. So altogether you have the chickenpox illness for two to four weeks.

After recovery, the chickenpox virus remains in your body for life. It can cause shingles later, a different form of disease caused by varicella zoster virus.

Answer 2

Once you've gotten chicken pox you don't need a vaccine. A vaccine is a small dose of the virus mixed with dangerous chemicals. A vaccine is injected into the body so that your white blood cells learn to recognize the virus and kill it. Once you've gotten the virus on your own, a vaccine is pointless.

Answer 3

Adults normally have one or two days of fatigue or achiness, followed by an average of seven or eight days from the first blister coming out until the blisters and sores are all crusted over. After that, it may be two or three weeks until the marks are completely gone, but the patient is no longer contagious once the lesions are scabbed.

Answer 4

A person with Chickenpox, or varicella zoster virus (VZV) is contagious for 1-2 days before the rash appears until 24 hours after all of the blisters are crusted over. Usually that takes about 7 days.

Any child with chicken pox should be kept at home and away from public places until the blisters are all crusted over.
7 days from when the first spot comes out. Bu once the spot scab over they are not contagious.
Children with chickenpox should be quarantined until all lesions have scabbed over. This may take a week or more.
After the spots have crusted over and dried up, it is no longer contagious.

If you're not sure if it's okay for the infected child/adult to return to school or work, ask a doctor.
After the Rash, and blisters have crusted over, then It is no longer Contagious.
When all your pox have crusted...

Answer 5

If you have contracted chickenpox even if you have been vaccinated, a shorter duration is likely, with total duration of illness as short as five days. In addition, the lesions may not crust over as the presentation is different, so those affected by breakthrough chickenpox after vaccination can return to school or work 24 hours after new lesions have shown up.

Answer 6

Chickenpox stays in your nervous system for life, and can reoccur later as shingles. It remains hidden in posterior root ganglion. It is not contagious after the lesions are scabbed over, though.

Answer 7

Perhaps. It takes a few weeks for the immune system to build up a protection, so if you are exposed very soon after the vaccine, it is possible.

Answer 8

A person with chickenpox is infectious one to two days before the rash appears, entails four or five days, by which time nasal shedding of live virus also ceases.

Answer 9

usually 2 to 3 weeks Max.
