Description: Caption:
Photographed in 1959, on the Caribbean island of Puerto Rico, this image depicted a seated sixth-grade pupil, who had received a skin test for schistosomiasis, on the back of her neck, in the region of the right trapezius muscle. From this posterior-superior view of the girl’s neck, the injection site was being exposed by the hand of a clinician, who was inspecting the test results. In this case, the raised wheal, or bump, and the surrounding erythema, was an indication that this was a positive site reaction. The antigen, delivered in an intradermal fashion, was prepared from Schistosoma spp. cercariae, adult worms, eggs, or miracidia.
