Malaria control health workers during the 1920s
This 1920s photograph shows three malaria control health workers before dynamiting tree stumps in Virginia to create proper drainage of standing water. The procedure is to drill a hole in a tree stump with the hand augur, held by the worker on the left; put sticks of dynamite in the holes; and set off the dynamite destroying the stump. Drainage ditches assist in the removed standing water in which the larvae of malaria vectors (anopheles mosquito) may reside.
