Crossing the digital divide: The contribution of information technology to the professional performance of malaria researchers in Africa

BACKGROUND: The US National Library of Medicine supports the Multilateral Initiative on Malaria (MIM) through the design, implementation, and operation of the Multilateral Initiative on Malaria Communications Network (MIMCom.) MIMCom makes possible enhanced access to the Internet and to medical literature. OBJECTIVES: The main objectives of the present study were to examine the use of MIMCom supported information technology (IT) by scientists, students, and administrative personnel to facilitate communication, retrieve information, obtain documents, write proposals, and prepare papers for publication; and to determine the contribution of this intervention to their professional performance. METHODS: The authors analyzed the contribution of enhanced Internet connectivity and access to electronic information resources to the performance of malaria research staff and their institutes through a cross-sectional questionnaire survey of 181 respondents at 14 health research centers in Africa. Separate reviews of bandwidth usage, requests for document delivery, and publications in peer reviewed journals support the data of the survey. RESULTS: The MIMCom network makes a positive contribution to the performance of malaria researchers and support staff at the sites reviewed by improving e-mail exchange, access to published literature, and research proposal development and submission. Implications of these findings are discussed. CONCLUSION: By providing full access to the Internet and the resources of the WorldWide Web, MIMCom has been shown to be invaluable to malaria researchers and their institutes in Africa. This access has increased visibility of scientists in their respective institutions and provided opportunities for stronger engagement with the international scientific community

El Niño causes dramatic outbreak of Paederus dermatitis in East Africa

KeywordsPaederus sabaeus; Nairobi Fly; outbreak; El Niño; Paederus dermatitis; conjunctivitis; Nairobi; KenyaAbstarctAn outbreak of Paederus sabaeus rove beetles in Kenya during the 1997–1998 El Niño resulted in a dramatic increase of vesicular dermatitis in its capital Nairobi. The beetle, popularly called ‘Nairobi Fly’, contains a potent toxic fluid that causes epidermolysis and acute conjunctivitis. A cross-sectional epidemiological study involving 1, 208 Nairobi residents was conducted to determine the health impact of this outbreak. The results showed that one-third of the Nairobi population were infected during this period. The majority of the respondents reported lesions on exposed body parts above the shoulders. Disfiguring, painful blisters and skin rashes in and around the facial area had a strong personal and social impact. Policy makers and public health specialists need to recognize that outbreaks of insects of medical importance resulting from global climatic events require urgent remedial action.INTRODUCTIONModern human activities have an obvious negative impact on the environment and contribute to the irreversible alteration of the global climate. Evidence shows that successions of abnormal climatic events have a disturbing effect on the world's ecosystems (Epstein et al., 1998). Rise of temperatures and more frequent occurrence of extreme weather conditions alter the flora and affect the development of competitive insect species in certain parts of the world, causing unexpected insect explosions with consequences for human health (Dukes and Mooney, 1999)

Human health improvement in Sub-Saharan Africa through integrated management of arthropod transmitted diseases and natural resources

A concept of an ecosystem approach to human health improvement in Sub-Saharan Africa is presented here. Three factors mainly affect the physical condition of the human body: the abiotic environment, vector-transmitted diseases, and natural resources. Our concept relies on ecological principles embedded in a social context and identifies three sets of subsystems for study and management: human disease subsystems, natural resource subsystems, and decision-support subsystems. To control human diseases and to secure food from resource subsystems including livestock or crops, integrated preventive approaches are preferred over exclusively curative and sectorial approaches. Environmental sustainability - the basis for managing matter and water flows - contributes to a healthy human environment and constitutes the basis for social sustainability. For planning and implementation of the human health improvement scheme, participatory decision-support subsystems adapted to the local conditions need to be designed through institutional arrangements. The applicability of this scheme is demonstrated in urban and rural Ethiopia
