First noticed in Uganda in 1863 by a European explorer, sexually transmitted diseases (STDs) were cited as a major cause of morbidity and mortality throughout this century.
Abstract. Infectious diseases ranging from the common cold to cholera affect our society physically, emotionally, ecologically, and economically. Yet despite their importance and impact, there remains a lack of effective teaching materials for epidemiology and disease ecology in K-12, undergraduate, and graduate curricula [2]. To address this deficit, we've developed a classroom lesson with three instructional goals: (1) Familiarize students on basic concepts of infectious disease ecology; (2) Introduce students to a classic compartmental model and its applications in epidemiology; (3) Demonstrate the application and importance of mathematical modeling as a tool in biology. The instructional strategy uses a game-based mathematical manipulative designed to engage students in the concepts of infectious disease spread. It has the potential to be modified for target audiences ranging from Kindergarten to professional schools in science, public health, policy, medical, and veterinarian programs. In addition, we've provided variations of the activity to enhance the transfer of fundamental concepts covered in the initial lesson to more complex concepts associated with vaccination and waning immunity. While 10 variations are presented here, the true number of directions in which the game might extend will only be limited by the imagination of its students [6].
SummaryWhen sleeping sickness was discovered to be epidemic in the Congo Free State in 1904, the administration responded by attempting to implement public health measures which had evolved in Europe in relation to plague and cholera epidemics. These measures were to identify and isolate victims and suspected victims of the disease and to map out the infected and uninfected zones. This article describes the early sleeping-sickness campaign of the Belgian authorities in the Uele District of Province Orientale between 1904 and 1914, focusing on the formation of isolation camps or lazarets. Uele district had been identified as a potentially rich and uninfected zone to be protected from contamination by the establishment of acordon sanitaire. Public health policy and practice during this period provides an example of attempted ‘social engineering’ on the part of a colonial authority. While sleeping sickness provided the major impetus for the gradual development of the colonial medical service by the 1920s, the early period between 1903 and World War I was particularly onerous for the African populations in the north-east. The public health policy was perceived by many Africans as one more element in the on-going conquest and exploitation of the region. Examples are provided to demonstrate the ways in which numerous sleeping-sickness regulations affected African societies in Uele.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
