Essay / Research Paper Abstract
A 12 page paper that begins with an explanation of infectious diseases. Beginning fifty years ago, the medical profession believed that infectious diseases were under control and in fact, believed that many had been eliminated entirely. That turned out to be a naïve assumption. Over the past two decades, we have seen both "emerging" and "re-emerging" infectious diseases become a major health problem in many geographic regions. This paper identifies some of the emerging diseases and some of the re-emerging diseases and discusses the factors involved in their appearance. The writer comments on bioterrorism but points to other reasons as being far more significant in both emerging infectious diseases and re-emerging diseases. Bibliography lists 8 sources.

Unformatted sample text from the term paper:
disease are called pathogens (National Institutes of Health, 1999). Infections occur when a pathogen begins growing in a host, such as in a human or animal (National Institutes of Health,
1999). The host contracts a disease when that pathogen interrupts the normal functioning of tissues (National Institutes of Health, 1999). The human body has a number of defenses that prevent
infection but if those defenses prevent infection, but even if these defenses fail, disease will not automatically occur (National Institutes of Health, 1999). There are many infectious agents that
are very contagious but they seldom cause diseases (National Institutes of Health, 1999). These agents are said to be "not very virulent" (National Institutes of Health, 1999). One good example
is the polio virus because, while it is very contagious, the disease develops in only 5 to 10 percent of the persons who become infected with this pathogen (National
Institutes of Health, 1999). Then there are highly virulent infectious agents that are not very contagious (National Institutes of Health, 1999). A good example of this type is the Ebola
hemorrhagic fever; it is not very contagious but it kills between 50 and 90 percent of those who become infected with the pathogen (National Institutes of Health, 1999). The
most concerning infectious agents are those that are both highly contagious and that are highly virulent (National Institutes of Health, 1999). While we might like to think that these virulent,
contagious infectious diseases have re-emerged because of terrorism, the fact is that except for a number of isolated incidents, most have reappeared as a result of human neglect, new
strands developing, or because the pathogen has evolved to be immune to treatments previously successful in preventing the disease. Emerging and Re-Emerging Infectious Diseases Beginning 50 years ago,
