Disease outbreaks in schools have posed challenges for decades. During the 1952-53 school year, school and health officials took hard measures to fight a scalp ringworm outbreak in Grand Forks. On this date in 1952, the Associated Press reported that the epidemic was sweeping eastern North Dakota, but it appeared to be centered in Grand Forks among children ages 5 to 10. Ringworm is a fungal infection of the skin, and at the time was diagnosed using ultraviolet light.
