The next change is dated about 7000 B.C., before the dawn of what we call history. It follows the retreat of the last glacial mass and the penetration of man into more temperate and drier regions. At this point endemic syphilis (bejel) emerges in arid warm areas while yaws continues in humid warm ones.
Late in 1970 a brief preliminary announcement was made of the discovery of another natural treponematosis of primates, in this instance in the dog faced baboon of Casamance, in the Senegal Gambia area of Africa. This animal shows definite disease, with lesions and typical paliidum like treponemes as well as characteristic blood tests.
The theory of the origin of syphilis now entertained by the more serious students of this subject. C. J. Hackett, has points of resemblance to, as well as points of difference from, the polio story. It may be just as well to emphasize that even two related virus diseases would not be identical, so that two diseases as far removed in the biological scale as polio and syphilis could not be expected to have many parallels.
It was after World War II that the effort really got going, making reputations and Nobel prizes, and leading on to spectacular success. These things you know or can easily learn elsewhere. What concerns us here are some of the lessons learned in the process.
The alternative to the Columbus idea of the origin of syphilis will be clearer if we say something first about a quite different disease, namely polio. Polio has been brought under control in the United States but is still well remembered by adults. Its conquest was the great post World War II triumph of American public health.
Pinta is different from the other treponematoses. It is much milder, with symptoms limited to the skin except for involvement of lymph nodes, and entails no physical disability. Its main signs are dry, scaly areas of skin in which there is first a bluish discoloration followed by loss of pigment.
Congenital syphilis, meaning infection passing through the placenta from syphilitic mother to the fetus in the womb, so that the baby is born with the disease, is most likely to happen if the mother has infectious syphilis after the fourth month of pregnancy. Depending on the severity of the disease, it may lead to spontaneous abortion (miscarriage) at any time after the fourth month, to a baby stillborn at the regular term, or to one born alive with syphilis, prematurely or not. Syphilis in such a baby is already generalized.
Studies in syphilis epidemiology have recently indicated that only early latent syphilis of under 1 year's duration produces sufficient infectious syphilis to warrant patient interviewing and contact investigation. Because of this finding several state health departments have already changed the definition of early latent syphilis to include only cases of less than 1 year's duration.
In syphilis these early lesions are usually painless and not destructive; that is, they heal, with or without treatment, with little or no scarring. A person who does not suspect what they really are may pass them off as of little importance. In yaws the early sores may be more severe and destructive, leaving deforming scars as they heal and even producing damage to bone.
No chancre has been recorded in any of the treponematoses other than venereal syphilis. It doesn't always appear even in syphilis. The first sign may be what is sometimes called the secondary stage. Terminology can be a little confusing here because it has been changing.
