HISTORY
Occupational disease has existed for thousands of years. Hippocrates (c460โ377 BCE) hypothesized that there were environmental causes of disease. One of the first written descriptions of occupational dermatoses was by the Italian Bernardino Ramazzini (1633โ1714). He described diseases associated with a variety of occupations, including different types of ulcerations in fresh- and salt-water fishermen. During their long-distance voyages in the sixteenth century, Drake and Magellan experienced significant problems from scurvy due to the lack of vitamin C from fresh fruit and vegetables. In 1747, James Lind performed the first controlled trial demonstrating the protective effects of citrus fruits against scurvy. In 1795, the British Navy included lemon juice in shipsโ stores as one of the earliest forms of prevention for an occupational skin disease.
