Plague and trade in Lagos, 1924–1931

The literature on the Third Plague Pandemic in West Africa focuses on urbanisation and disease processes in colonial Senegal, Ghana, and Nigeria. Consequently, there is a dearth of historical study of the relational complexities between public health interventions and maritime trade during the outbreak in the region. It is with this in mind that this article examines the historical effects of plague control on internal commerce and international maritime trade in Lagos from 1924 to 1931. The study is based on the historical analysis of colonial administrative, sanitary and medical records as well as newspaper reports. It concludes that the nature of colonial public health intervention was determined by economic policy preferences that impacted distinctively on internal commerce and international maritime trade in Lagos.
