In December South Dakota saw its first case of measles since 1997. It was part of a Mitchell outbreak that resulted in 13 cases. An additional case unconnected with the Mitchell outbreak was reported in Sioux Falls on January 24. Nationwide there have been over 150 cases of measles since December, most connected to an outbreak at Disneyland. Measles is a highly contagious viral disease and the best protection is the measles vaccine.
