Abstract

At the end of the nineteenth century, Hong Kong was in the midst of a malaria and plague epidemic which caused a fierce dispute within the medical community over disease theories and quarantine practices. However, the Hong Kong colonial authorities and medical community did not immediately accept the theory of etiology based on germ theory. Although germ theory was becoming scientifically established through research on plague and malaria in the 1890s, the Hong Kong colonial authorities and medical community did not immediately accept it.
Patrick Manson (1844-1922) began studying tropical medicine based on germ theory by studying elephantiasis and malaria in Amoi and Hong Kong during the 1880s. However, he was unable to strongly advocate for a quarantine policy based on germ theory because the exact transmission routes of these diseases were not yet fully understood. Although the scientific community began to shift towards germ theory after the discovery of causative bacteria for diseases like malaria and plague in the 1880s and 1890s, many medical and colonial health officials in Hong Kong still held on to the quarantine policy based on miasma theory. However, a series of infectious diseases and destructive miasma theory-based quarantine measures were pushing Hong Kong society into chaos, and the existing quarantine measures was no longer sustainable.
In the twentieth century, colonial authorities and medical community in Hong Kong adopted tropical medicine and quarantine measures based on germ theory as their prominent position. Despite the establishment of tropical disease theory based on germ theory, racial perceptions of disease did not change significantly. Instead, the theory of tropical medicine reinforced orientalist views of disease.
