Chickenpox is a highly contagious disease caused by the Varicella Zoster Virus (VZV). The virus causes an itchy, blister-like rash, tiredness, and fever.  The rash first appears on the stomach, back and face and can spread over the entire body.  The virus is easily spread from person to person. The best way to prevent the disease is to get vaccinated.

The Waukesha County Public Health Division is working with schools to encourage proper chickenpox vaccination among their student population. As part of the childhood immunization program the first dose of chickenpox vaccine is given between 12 – 15 months of age. The second dose is recommended before entering school at 4 – 6 years. The Wisconsin Immunization Law requires students in pre-K (ages 2 – 4) to have 1 dose of chickenpox vaccine recorded; students in 5K through 12th grade are required to have 2 doses of chickenpox vaccine on file.

Vaccinated individuals with known chickenpox exposure can present with atypical rashes. Healthcare provider evaluations are encouraged.
