Examination of a child for hookworm in a P.R.R.A. (Puerto Rico Resettlement Administration) centre, San Juan, Puerto Rico, in 1938. Hookworm is a parasitic infection affecting millions of people worldwide. Heavy infestations of hundreds of worms can cause enough blood loss to kill the victim. P.R.R.A. centres were set up to provide relief and healthcare to Puerto Ricans after a number of hurricanes and crop failures in the 1920s and 1930s. | |
