The state of South Carolina has officially declared the end of its measles outbreak, which has sickened nearly 1,000 people. This outbreak is notable for being the largest in the U.S. in decades. Health officials reported no new cases in the past two months, and the incidence of measles has significantly decreased. The outbreak may have contributed to a surge in vaccination rates as health authorities emphasize the importance of maintaining high immunization levels to prevent future outbreaks.
