Anopheles mosquito, carrier of malaria, Culex mosquito , the carrier of encephalitis, filariasis and West Nile Virus and Aedes mosquito, the carrier of yellow fever, dengue and encephalitis. Aside from these diseases, there are other diseases caused by mosquitoes like chikungunya and dog heartworm. According to the World Health Organization, mosquito bites were responsible for the deaths of more than one million people every year and most of it were due to malaria. Numerous type of mosquito
parasites that transmitted to people through the bites of infected female mosquitoes. It is an estimated that 3.2 billion people, almost half of the world's population, are at risk of malaria. Most cases and deaths occur in sub- Saharan Africa; Africa shares 89% of cases and 91% of deaths[30]. Malaria cases would be raised by the high levels of HIV infection, which weaken the immunity rendering people with HIV more susceptible to contracting the disease [10]. It enhances the mortality rate for HIV
continuing to danger everyone until now. Even though some diseases have been effectively controlled with the help of modern technologies, yet new diseases are constantly appearing and even some are resistant to drug treatments. There have been many studies on the factors, effects and treatments against infectious diseases in human as well as in animals which carried out by the scientific community around the globe but the infectious diseases continue to be increasing from time to time.

CHAPTER ONE INTRODUCTION 1.1 Background of the study Dengue is an arbovirus disease complex which includes dengue fever (DF) and dengue hemorrhagic fever (DHF) and its subsequent dengue shock syndrome (DSS). It is caused by four serotypes of dengue virus. A dengue virus infection may be asymptomatic or it may lead to undifferentiated viral fever syndrome, dengue fever, fever hemorrhagic fever or dengue shock syndrome. (World Health Organization 2003) The disease is often, though not exclusively
has caused numerous epidemics with high mortality rates throughout history. Its etiologic agent is the yellow fever virus, an arbovirus of the genus Flavivirus (family Flaviviridae).27 The virus is transmitted to people by the bite of an infected mosquito. Illness ranges in severity from a self-limited febrile illness to severe liver disease with bleeding. Yellow fever disease is diagnosed based on symptoms, laboratory testing, physical findings and travel history, including the possibility of exposure
potentially profitable location to build their latest state of the art hotel and have initiated this chapter of the project is to analyze the opportunities of developing this hotel by analyzing the cost, duration of such a project, a brief history and study of the location and the personnel required for the activities of the project, and a potentially great business hotspot. This chapter will focus
