Delaware measles outbreak grows in Kent County, mostly among the unvaccinated

Delaware's Division of Public Health declared a measles outbreak in Kent County after eight confirmed cases, seven unvaccinated and one in a child under 10; a fully vaccinated person had milder symptoms. National measles cases are rising. Experts warn the most at-risk are unvaccinated individuals and those who cannot be vaccinated; measles is extremely contagious and can spread before symptoms appear. The vaccine is about 97% effective with two doses, and high vaccination coverage is key to preventing future outbreaks.
