I was in grade school in the 1950s. My Catholic school was in a Polish neighborhood where many refugees — “DPs” — from Hungary found shelter. I remember many DP children coming to school with finely-knit stocking caps that they wore in class; we were told they had ringworm &amp; had medication on their scalps to control the disease. Periodically a public health nurse would come to the school and inspect all of us children for ringworm. I recall having my head examined with tongue depressors.
