This new nomenclature, recommended by the Venereal Diseases and Treponematoses Section of the World Health Organization, outmodes terms such as mother yaw, daughter yaw, ghoul hand, crab yaws, etc. The classification consists of two main groups: early yaws and late yaws. Under early yaws, there are included the various types of initial yaws: cutaneous early yaws; mucosal early yaws; early yaws of bones and joints, palms, and soles, and latent early yaws. Late yaws is also subdivided into cutaneous yaws, osseous, latent, etc. If the classification still seems a bit confused, it is only because the manifestations of the disease are such that they will not lend themselves to simplified classification.
Seventy-five of the one hundred pages consist of as fine a collection of photographic illustrations of yaws as one could wish for. The photographic collection is well worth the cost of the book.
