Parasitic diseases continue to constitute immense public health problems and obstacle to socio-economic development in
endemic communities in the world (including Africa). Six of these diseases namely; Malaria, African Trypanosomiasis,
Onchocerciasis, Lymphatic Filariasis, Schistosomiasis and Leishmaniasis have been tagged “major tropical diseases” by the
World Health Organization. The surveillance of these diseases remains an essential first step in their control, eradication and
prevention. However, surveillance using conventional methods in some instances is time consuming, expensive and
impracticable over wide ranges of ecological conditions. The need therefore to introduce new techniques and alternative
ways of parasitic disease surveillance, prevention and control becomes expedient. Satellite techniques are new and modern
methods that are technologically driven and hold much promise for parasitic disease surveillance, control and prevention in
Africa. These techniques include: remote sensing, geographical information system (GIS), and global positioning system (GPS). Other complimentary techniques at various stages of
development include: human and robotic teams and
telemedicine. The potential application of these techniques
in the surveillance, control and prevention of parasitic diseases
in Africa is explored in this write-up.

Keywords: surveillance, parasitic diseases, satellite techniques, remote sensing, Geographical Information System
(GIS), Global Positioning Sytem (GPS), human and robotic, telemedicine.
