Determining susceptibility to scarlet fever. Drs. George and Gladys Dick, husband and wife, developed the skin test. They proved that scarlet fever is caused by streptococcus. As a result, they produced a vaccine and an anti-toxin against the disease. Before this, scarlet fever which largely affects children had a 25% mortality rate. In other cases, it left lasting consequences.
