South-to-North, cross-disciplinary training in global health practice: ten years of lessons learned from an infectious disease field course in Jamaica.

Global commerce, travel, and emerging and resurging infectious diseases have increased awareness of global health threats and opportunities for collaborative and service learning. We review course materials, knowledge archives, data management archives, and student evaluations for the first 10 years of an intensive summer field course in infectious disease epidemiology and surveillance offered in Jamaica. We have trained 300 students from 28 countries through collaboration between the University of the West Indies and U.S. partner universities. Participants were primarily graduate students in public health, but also included health professionals with terminal degrees, and public health nurses and inspectors. Strong institutional synergies, committed faculty, an emphasis on scientific and cultural competencies, and use of team-based field research projects culminate in a unique training environment that provides participants with career-developing experiences. We share lessons learned over the past decade, and conclude that South-to-North leadership is critical in shaping transdisciplinary, cross-cultural, global health practice.

Absence of impact of aerial malathion treatment on Aedes aegypti during a dengue outbreak in Kingston, Jamaica

During an outbreak of dengue fever in Jamaica from October to December 1995, a study was carried out to determine the impact of aerial ultra-low volume malathion treatment on adult Aedes aegypti. This was done by monitoring oviposition rates of the vector in three urban communities in Kingston and by exposing caged mosquitoes both directly and indirectly to the aerial malathion treatment. The insecticide was delivered at a rate of 219 mL/ha between 7:10 a.m. and 8:45 a.m. The results of the study clearly showed that the insecticide application was ineffective in interfering with Aedes aegypti oviposition, and adult mosquitoes held in cages inside dwellings were largely unaffected. Consequently, this type of intervention seemed to have little significant impact in arresting or abating dengue transmission (Au)

This was done by monitoring oviposition rates of the vector in three urban communities in Kingston and by exposing caged mosquitoes both directly and inirectly to the aerial malathion treatment. The insecticide was delivered at a rate of 219 mL/ha between 7:10 a.m. and 8:45 a.m. The results of the study clearly showed that the insecticide application was ineffective in interfering with Aedes aegypti oviposition, and adult mosquitoes held in cages inside dwellings were largely unaffected.

Durante un brote de dengue que ocurrió en Jamaica de octubre a diciembre de 1995, se llevó a cabo un estudio a fin de determinar el impacto del rociamiento con volúmenes muy bajos de malatión en mosquitos Aedes aegypti adultos. Se observaron las tasas de ovipostura del vector en tres comunidades urbanas de Kingston y se expusieron mosquitos colocados en trampas directa e indirectamente a rociamientos aéreos con malatión. El insecticida se roció a una velocidad de 219 mL/ha entre las 7.10 y las 8.45 h. Los resultados del estudio claramente demostraron que la aplicación del insecticida no interfirió con la ovipostura de Aedes aegypti, y los mosquitos adultos colocados en trampas dentro de las viviendas casi no sufrieron ningún efecto. Por consiguiente, este tipo de intervención parece haber tenido muy poco impacto en la interrupción o atenuación de la transmisión del dengue.

Malaria revisited: "Jamaican perspective" - abstract

A retrospective study of all reported smear-positive cases of malaria in Jamaica between 1966 and 1989 was undertaken. There were 76 cases of imported malaria. Fourteen (14) of these cases were seen and treated at the University Hospital of the West Indies or at the University Health Centre. The results and their implications are discussed (AU)
