Solution Preview

I have chosen poliovirus because it is a well-understood disease in terms of both the epidemiology and disease process.

Introduction
Poliomyelitis was once one of the most feared diseases, stoked mostly by our poor understanding what caused the disease and how it spread. In modern times the incidence of disease is very well controlled in developed countries, and it is an excellent example of the triumph of public health and vaccination over an horrific disease.

causative agent
The disease poliomyelitis is caused by poliovirus, a virus in the picornavirus family. The virus is a non-enveloped single stranded RNA virus with a positive sense genome, and the virion consist of an icosahedral capsid comprised of multiple copies of four different viral proteins. It is stable in the environment, allowing the virus to survive in sewage-contaminated water, which is the main route of transmission.

pathogenesis
Poliomyelitis is a rare outcome of poliovirus infection, occurring in approximately 1% of all cases. Virus is shed in the feces from infected individuals and can enter into the water supply under conditions of poor sanitation. Contaminated water is ingested and the virus infects lymphoid cells in the gut, where it ...

Solution Summary
