Chickenpox is a very contagious infection caused by a virus.
How do you get chickenpox?
It is spread from person to person by direct contact or through the air from an infected person’s coughing and sneezing. Chickenpox can be spread for 1-2 days before rash starts and until all blisters are crusted or no new lesions appear within a 24-hour period. It takes between 10-21 days after contact with an infected person for someone to develop chickenpox.
If I have been vaccinated, can I still get chickenpox?
Yes. About 15%-20% of people who have received one dose of chickenpox vaccine do still get chickenpox if they are exposed, but their disease is usually mild. Two doses of varicella vaccine are now routinely recommended. The first dose can be given at 12 months of age and the second dose between 4-6 years of age.
Certain groups of people are more likely to have more severe illness with serious complications. These include adult, infants, adolescents, pregnant women, and people have a weakened immune system. If anyone develops symptoms that look like chickenpox, contact your health care provider.
