DAVID HOSACK OF NEW YORK DESCRIBES AN EPIDEMIC OF GERMAN MEASLES IN 1813
Physicians of the seventeenth and eighteenth centuries probably observed cases of rubella, but it was not until 1829 that it was finally separated from measles and scarlet fever and considered as a distinct entity.1 David Hosack (1769-1835)2 observed an epidemic of an eruptive disease in New York in 1813 resembling measles. His description fits that of rubella and was far better one than any other report of this disease until Henry R. Veale's (1832-1908)3 in 1866. Hosack wrote: An eruptive disease in many respects resembling the measles, has prevailed to a considerable extent during the last three months [1813]. Such was the resemblance it bore to the measles in its invasion, the character and extent of the eruption, that by many it was called the French measles. It, however, differed from the measles (rubeola vulgaris) in several particulars. The fever preceding the eruption, was very inconsiderable in degree, and of short duration, not more than twenty-four hours; and in some few cases the eruption appeared without any preceding fever; the eruption itself generally disappeared at the end of the second or beginning of the third day; the eyes were rarely affected with it as in measles, and in no cases as in the latter disease, was it attended with cough or oppression, excepting such as are attendant upon most febrile complaints. In several cases this disease occurred in children, who some time afterwards, were attacked with the measles, attended with all its characteristic symptoms, and in other instances, adults who were certainly known to have had the measles in early life, were the subjects of this eruptive complaint.
