The Vermont Department of Health is investigating its first case of measles in 10 years.
Officials say the disease was confirmed in an unvaccinated person from southern Vermont.
The last case of measles was reported in Vermont in 2001.
Health Commissioner Harry Chen says every child in Vermont who is eligible should be vaccinated against measles to avoid illness and the very serious consequences that may occur with the disease.
Health officials say while the disease is uncommon in the U.S. it has turned up in some areas this year. Through May 20, 118 cases have been reported in Minnesota, Utah, Massachusetts, New York and Rhode Island. Officials say many of the cases are due to exposures from other countries, such as France, which is currently experiencing a measles outbreak.
