Description:This historic 1952 image showed Dr. Malcolm Ferguson as he was examining the arm of Dr. Scragz for any signs of possible schistosomiasis infection, while they were seated in the Centers for Disease Control’s Puerto Rican Schistosomiasis Laboratory.
One is infected with schistosomes while swimming in water that has been infested with these parasitic worms, which enter the affected water supply when other people who are infected urinate or defecate into the water, thereby, liberating eggs of this parasite. The eggs then hatch, liberating miracidia, and find refuge inside the bodies of certain types of snails, where they mature before leaving the snail to re-enter the water, in a form known as cercariae. It is these cercariae that find a human host in their water environment, and penetrate the skin. Where the cercariae penetrate the skin one will often see an itchy, reddened, papular rash.
