how long are you contagious with chicken pox?

Question

period before spots come out and after

Answer 1

Contagiousness
Chickenpox is contagious from about 2 days before the rash appears and lasts until all the blisters are crusted over. A child with chickenpox should be kept out of school until all blisters have dried, usually about 1 week. If you're unsure about whether your child is ready to return to school, ask your doctor.

Chickenpox is very contagious — most kids with a sibling who's been infected will get it as well, showing symptoms about 2 weeks after the first child does. To help keep the virus from spreading, make sure your kids wash their hands frequently, particularly before eating and after using the bathroom. And keep a child with chickenpox away from unvaccinated siblings as much as possible.

Chicken pox has an incubation period of up to 3 weeks. So you will have it and be contagious and not even know, thats how comes when it goes around every kid in the class gets it. When she spots are scabbed over it is no longer contagious.

My daughter got it at nursery then 3 weeks later my son and baby got it too!!!

Answer 5

Well, they have answered your question, but I became a slight medical marvel when I was eight as I managed to get this particular diesease three times! Which is apparently impossible. Had some blood taken and all that jazz(including an AIDS test my dad told me later on), but they never tracked down why I kept getting it, I think that for some reason I just never made the antigens needed to become immune to it, and ended up having about 1000 boosters for my rubella and tetunus.

When they did the BCG on me at school, it didn't show up at all, so I was completely immune to that, a big surprise to everyone, and that started off another ton of blood tests. Which showed I had antibodies to everything! Though I suffered through 'the pox' three times, I never got anything else at all, not measles, mumps, whooping cough or anything, which just might be the sheer number of vaccinations i got, but I just like to think I'm a bit weird and special.
Anyway, I know this is totally none related to your question really, but you never know, I can't be the only person who gets it more than once!

Answer 6

The incubation period between exposure and the first skin lesions is around 10 to 14 days but can be as long as 21 days. You usually develop symptoms about ten to twenty-one days after being exposed to someone with chicken pox (incubation period).

Chicken pox is spread by both direct contact with an infected person and through air borne spread of respiratory secretions. Since infected persons are contagious for 1-2 days before they even develop a rash, you may have been exposed to someone with chicken pox without knowing. You can also get chicken pox after having direct contact with someone who has shingles or herpes zoster, a reactivation of chicken pox.


The first feature is often pyrexia. A temperature of around 38 to 39ºC is usual for up to 4 days. Infection with chicken pox and subsequent immunity can occur without clinical disease. Headache, malaise and abdominal pain may be reported.
Crops of vesicles appear over the course of 3 to 5 days. They are mostly on the head, neck and trunk and very sparse on the limbs.
The lesions tend to be very itchy but perhaps less so in younger children. They pass through the stages of papule, vesicle, pustule and crust.

When the crusts fall off they may leave marks that may be present for a few weeks but there is normally no long term residue. However, in adolescents and adults there is a greater risk of scarring.
Redness around the lesion may suggest bacterial superinfection, probably introduced by scratching.
Lesions may occur in the oropharynx. Little girls may get vulval lesions that are very unpleasant.

Answer 7

People who have chickenpox become contagious 24 hours (and sometimes as long as 48 hours) before breaking out. They remain contagious while uncrusted blisters are present, usually one week or less after breaking out. Chickenpox is extremely contagious, and can be spread by direct contact, droplet transmission, and airborne transmission.
