Randolph Center — Vermont Technical College warned members of its community of one confirmed case of chickenpox in a student on its Randolph campus on Wednesday.

The disease, known for it’s blister-like rash, is very contagious, so the college — which in Randolph has about 400 residential students and about 700 students in total — is urging members of its campus community to be diligent about hand washing, said Amanda Chaulk, the college’s director of marketing and communications.

She said she hopes that those who are at greater risk, such as those with compromised immune systems or those who are pregnant, take note of this information.

“They may elect to not return to campus for a period of time,” Chaulk said.

While complications from chickenpox can occur, most healthy people who get the disease will recover in five to seven days, Ben Truman, spokesman for the Vermont Department of Health, wrote in an email. In addition to the rash, common symptoms include fever, fatigue, loss of appetite and headache.

Most people are immune to chickenpox due to previous childhood vaccination or history of disease, Truman said. But college officials will review students’ immunization records and contact those who might be at risk, according to a health alert on the college’s website.

Students and employees who have not had chickenpox or been vaccinated against it can get the vaccine at the Randolph-based Gifford Medical Center or from their health care provider, according to the alert.

Two doses of the vaccine, which became available in 1995, are required for school entry in Vermont, Truman wrote.

“Outbreaks of vaccine-preventable diseases reinforce the importance for all of us to make sure that we and our children are up to date on our vaccinations,” he wrote.
