How is chickenpox spread?
Chickenpox can be spread through contact with droplets from the nose and throat of someone who is infected. The droplets move through the air when the person coughs or sneezes. Chickenpox can also be contracted by touching an infected person’s blisters.
A person with chickenpox is contagious 1 to 2 days before their rash appears and remains contagious until all their blisters are dried and crusted.
When chickenpox is gone, the varicella virus stays in the body as an inactive virus. If the virus becomes active again, it is called herpes zoster, or shingles. Herpes zoster usually develops in people who have serious illnesses or weakened immune systems.Back to top
What happens if someone has been exposed to chickenpox?
If someone is at risk for chickenpox and has spent time close to a person who has the infection, they will be observed to see if they develop it. It usually takes 10 to 21 days for the symptoms of chickenpox to develop after someone has been exposed to the infection. This is called the incubation period. Doctors and nurses can determine the incubation period for each person that was exposed. Please tell your doctor or nurse if you or someone you live with has been exposed to chickenpox.Back to top
