This paper provides a structured outline of malaria as an infectious disease, identifying the Plasmodium genus as its causative agent and classifying it as an emerging disease in high-risk regions. It examines the microbiology of Plasmodium falciparum, discusses current control and treatment strategies — including mosquito population control, community education programs, and quinine therapy — and proposes a framework for vaccine development. The proposed vaccine strategy focuses on transmission modeling, immune system strengthening, and the potential for mosquito inoculation as an alternative approach to protecting large at-risk populations from parasitic contagion.
In any investigation of infectious disease, one must first assign a causative agent. The purpose of this investigation is to ascribe a causative agent to the infectious disease malaria. Multiple studies of malaria provide ample evidence that the causative agent for infectious malaria is a parasite of protozoan, single-celled formation, recognized under the Plasmodium genus (Eisenberg et al., 2002). Such pathogens may be found in water; thus, malaria is often referred to as a "waterborne" disease, carried most often by insects, including the mosquito (Eisenberg et al., 2002). For the purposes of this investigation, malaria may be considered an "emerging" disease, as outbreaks and epidemics of malaria are quite common in certain regions of the world.
For malaria to result in contagion, the agent must infect the bloodstream of the host. It is most often carried through mosquitoes or other insects to humans by way of a bite, which allows entry to the bloodstream. The microbiology of the Plasmodium falciparum malarial agent identifies it as a single-celled protozoan parasite found widely throughout areas including Asia, Africa, and other tropical environments (Eisenberg et al., 2002; Ross, 1908; Koopman and Longini, 1994).
The most current tool for controlling the epidemic transmission of malaria to human populations is mosquito control, as the disease largely spreads via this parasitic host. During times of outbreak, it is critical that agencies help control mosquito populations through various means, including by spraying agents that kill or destroy the embryos or eggs of developing populations of parasitic hosts (Ross, 1908; Koopman and Longini, 1994; Eisenberg et al., 2002).
Other treatments used in countries where outbreaks are relatively frequent include local educational programs that teach residents and mothers to detect the symptoms of an infection early and treat their children or other patients promptly, resulting in better health outcomes across the population (Ethiopian, 2000). There are currently drugs that help fight malaria, but key to their efficacy is early administration in the course of the disease (Ethiopian, 2000). One agent often used to help treat the symptoms of malaria is quinine, which is effective when used early in the disease process (Kiple, 682).
