A case of measles has been confirmed in Steuben County.
The county health department says it was informed about the case on Aug. 18.
Officials say the resident, who was unvaccinated, is safely isolating at home until they are no longer contagious.
The health department is conducting contact tracing and has identified potential public exposure sites.

While health officials say the risk of measles is low for the general public, especially those who have been vaccinated, the disease is still extremely contagious.
