The public health angle of dengue is quite broad and widespread. I think this would be a very interesting topic. One of the potential public health models that could be used is the health belief model. In order to understand and curb the spread of dengue you can assess people's perceived susceptibility of contracting dengue, severity of what dengue causes (death), barriers (cleaning mosquito breeding sites), and benefits (cleaning the environment brings benefit. I have provided some excellent links on this topic to start you off.

There are a lot of theoretical and mathematical epidemic models on dengue, and you can just google epidemic model of dengue or look at G. Chowell's publication link and references therein: http://chowell.lab.asu.edu/publications.html
You may use statistical models, epidemiological models and Geographical Information System (GIS)-based models for your study. In my MBA dissertation, I utilised GIS for location-specific data analysis and superimposed the same on to SPSS for correlation and related analysis. I am sending to you a list of related references, which may be perused at toy end. Good luck
As if it is epidemic first do secondary data analysis of earlier epidemic in relation to various determinants to prepare preparedness methodology for predicting epidemic
If u want to study epidemic u can have the questions including sociodemographic factors,symptoms observed and clinical output of the patients along with assessing the breeding places of mosquitoes.
I tried several times to send you a chapter in my book Ziekte en zorg. Inleiding in de medische sociologie (2007). It is written in Dutch. Unless you have a good translation program, it is probably not very useful for you. Moreover, I am not sure about your e-mail address.The Anderson model makes a distinction between need variables, predisposing varables, enabling factors and systemfactors. Need variables in the case of Dengue fever have been clearly outlined by Sergei Esipov. Dengue fever is a serious, acute complaint, which needs immediate medical attention. (I don't now about the possibilities of prevention). A second need variable is illness behavior. Examples are pain. Fear can be a variable delaying seeking help. Predisposing factors are related to confidence in medical care. Not everybody trusts the health care system. Another predisposing factor is beliefs about illness. If people care a lot about health, they will go sooner to a doctor than those who do not. Another predisposing factor is habit. If you are born in a family which is used to go immediately to a doctor in case of need, you will often see the same pattern in the children. Enabling factors are for example the distance to health care facilities, the density of medical doctors or other health care providers. The available time is also important. Are there waiting lists? A mother with small children has usually less time at her disposal than other people.Personal or household insurance coverage is important. Household income and financial situation are clearly also crucial. Culture is another enabling factor. In case of wide cultural differences between the patient and the health care provider, delay in seeking help could be expected. And last, there are the characteristics of the health care system. The relationship between supply and demand is important. If there is a shortage in the supply of services for dengue fever than demand will be halted. The insurance system as a whole plays a role. The organization of health care: In Europe the role of the general practitioner is important but I guess that will be different in Pakistan.Factors related to the medical of health care practitioner: how defines the health care practitioner his/her role? Is he/she inclined to wait and see or to intervene immediately. Practices of the last kind will encourage medical consumption.
As before, I would encourage to have a look at the original article and also consult the WHO site.
I have some paper published about Dengue epidemic model, mainly when it is considered climatic variables, as temperature variation and rainfall regimes, on model's parameter set.
Please, take a look in then! I hope they are usefully to you!
