(Note: The following is part of a series of columns looking at the establishment and growth of doctors, hospitals and the health industry in Georgia and Bulloch County.) In Dr. W.C. Daniell’s 1826 book, "Observations upon the Autumnal Fevers of Savannah," he shared his early conviction that "the character and treatment of our autumnal fevers were yet to be learned." Daniell explained the cause of the 1820 yellow fever epidemic: "a very great number of labouring Foreigners, and especially Irish, came to the United States. … Very many … arrived in (Savannah) in (1819). ... Our city was literally thronged with them. Every tenantable house was crowded … the great fire of January, 1820, dispossessed very many … (W)here these people mostly lived (is where) the fever (first) made its appearance."
