Book Description

Excerpt from Infantile Paralysis in Massachusetts During 1910The last year has been one of considerable progress in our knowledge of infantile paralysis. The disease has been widespread in the United States; 23 States have made the disease reportable, and several State boards of health have taken up the work of investigation. The clinical study of cases has become more accurate and careful, and the importance and frequency of abortive cases has been much more fully recognized.Three certain interesting contributions to our knowledge are as fol lows: Osgood and Lucas found an active virus in the nasopharyngeal mem brane of one monkey, who had recovered from the acute attack, five and one-half months afterward, and in another six weeks afterward. This virus was sufficiently active to cause paralysis in a first and second gen cration of monkeys into which it was injected.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
