Types of Pathogens: Bacteria, Viruses, Fungi, and Protozoa
Pathogens are disease-causing microorganisms. Four of them are virus, bacteria, fungus and protozoa. They cause separate kinds of diseases, which are transmitted and develop into infections in different ways. This paper summarizes their individual characteristics, how they differ from one another, how they are transmitted into their separate hosts and how the disease process happens in each of them.
Vaccinations and Public Health
We live in the 2000s not the pre- and early ‘50s when polio was a disease as feared then as cancer is today. It is partially thanks to a determined and crippled president as well as to the public desire to eliminate the disease – and to the courageous and resilient Dr. Salk – that polio was mastered. The elimination of polio was based on one simple vaccine that had been thoroughly scientifically tested before it could be administered to even one individual. The repetitive success of the vaccine makes it a valuable and reliable intervention. Vaccines, therefore, are not only helpful but also critical interventions to eliminating and preventing national, if not global, scourges. It is the argument of this essay, therefore, that government should do all that it can to insist that unwilling parents vaccinate their children for the good of the country.
