Chickenpox is a relatively harmless illness that causes red, itchy spots or blisters on the skin. In most cases, it affects children and generally poses no serious risk. The virus can live on surfaces outside of the human body.
Generally speaking, viruses are unable to live for more than a few hours outside of the human body.
People who should take precautions to avoid carriers of the virus, as well as the toys of children who have chickenpox, include adults who never had chickenpox, some pregnant women and people with compromised immune systems.
The chickenpox virus typically dies within a few hours on hard surfaces, although it can take as long as 24 hours.
Soft toys can hold moisture better than hard surfaces, meaning that saliva, mucus and other bodily fluids infected with the virus take longer to evaporate. Once the fabric has dried, the virus is vulnerable.
Killing the Virus
You can kill the chickenpox viruses by cleaning toys with bleach or rubbing alcohol.
