Virus Disease: It has long been suspected that infectious mononucleosis, predominantly a disease of young adults, is caused by a virus disease; but attempts to isolate the virus disease have been unsuccessful. Recent evidence, however, indicated strongly that the agent responsible is the virus disease of Burkitt's lymphoma, a virus disease that is associated with a rare tumor of man in certain regions of Africa. It now appears that a high proportion of adults in other parts of the world have devel¬oped antibodies to the virus disease, indicating previous infection with this or a closely related virus disease; a number of patients with infectious mononu¬cleosis exhibited an acute rise in the level of these antibodies in the course of the infection.
When it was shown that the brains of diseased animals contained the virus disease, the way was opened for prevention of the disease. In 1885, Louis Pas¬teur successfully treated a peasant boy, severely bitten by a rabid dog, with a series of injections of a preparation of the virus disease. In the early 1900's characteristic changes in the nerve cells of in¬fected human beings and animals (Negri bodies, after Adelchi Negri) were first described. This discovery permitted rapid diagnosis of the disease.See Also The Disease Is Prev-nt:Such control measures have been effective in eventing rabies in Great Britain, the Nether-ids, Switzerland, Austria, Canada, and several tes in the United States. The disease is prev-nt, however, in Mexico, Spain, Italy, and ia (especially in India and the Near East), bies has been found in bats in Mexico, Central icrica, the United States, and Europe; vampire s in these areas may be important in the spread the disease there.

Thus, this kind of heart disease has been practically eradicated, al¬though rare cases are still encountered in elderly people. Other endocrine disorders affecting the heart are very rare.
Congenital Heart Disease. With the increasing control of rheumatic heart disease it is probable that congenital cardiovascular disease will soon outstrip it in incidence, and with the increasing control of high blood pressure, congenital heart disease will take second place. An interesting statistical fact is that in the 1920's, T. Duckett Jones and Paul Dudley White found that con¬genital heart disease made up only 1.5% of all of 3,000 patients with Signs or symptoms of heart disease.
On The Other Hand See Heart Disease ":Although most of the causes of Heart disease " disease observed in the first quarter of the 20th century are still present, their relative proportions have changed considerably, and some causes that were mentioned only occasionally or not at all at that time are considered common today. This is espe¬cially true of the virus infections. In some parts of the world the diagnosis of "Heart disease " disease of unknown origin" is a common one. In the United States such a diagnosis exists but is uncommon, and a few kinds of Heart disease " disease that are com¬mon in certain other countries are rare or non¬existent in the United States. For example, Chagas' disease (myocardial trypanosomiasis) is a parasitic infestation of the Heart disease " common in South America.
He maintained that the causes of Heart disease " disease deserve first priority since the prevention of Heart disease " disease, the ulti¬mate goal, depends upon determining the causes. In a follow-up to this article, the American car-diologist Paul Dudley White published the first edition of his textbook Heart disease " Disease (1931), emphasizing the etiological, or causative, diag¬nosis first, followed by structural and functional diagnoses in that order. |
