Abstract
Malaria has been described as one of the most dangerous and widest spread tropical diseases, with an estimated 247 million cases around the globe in the year 2006 alone. This calls for urgent scientific interventions. Since malaria is a vector borne disease, this research tackled the issue of malaria transmission from the angle of vector detection through a search engine. There are observed cases of attempting vector control on a trial and errors basis, with no scientific way of determining the locations of critical vector densities. Unfortunately, such a practice leads to waste of resources on the wrong places, while ignoring the areas of critical vector existence. This research formalizes a contact network using a number of attributes of the malaria vectors, the public places, and the human beings that affect malaria transmission. The resulting structure is a heterogeneous bipartite contact network of two node types - the public places and the human beings nodes. The human beings are those who have suffered from malaria, even when their residential homes were under reliable vector control. Such an exclusion principle makes it obvious that these people, most probably contacted the disease from outside their residential homes. The Hypertext Induced Topical Search (HITS) web search algorithm was adapted to implement a search engine, which uses the bipartite contact network as the input. MATLAB was used to implement the model system. The output shows the public places which habour the infected malaria vectors, and their corresponding vector densities. The model output was validated with UCINET 6.0 as the benchmark system. A root mean square error (RMSE) value of 0.0023 was obtained when the output of the benchmark system is compared with that of the search engine model. This result indicates a high and acceptable level of accuracy.
