Disease Dangers from Biological Evidence

Abstract

It has been always a great risk to collect biological evidences for any of the purposes, specifically in cases where safety guidelines are not properly followed. While conducting a test at laboratory to collect biological evidences, any failure to follow safety instructions can cause threat of serious disease to both laboratory technician and patient who are being tested. The aim of writing this paper was to examine the threats and risks associated with collection of biological evidences in laboratories. It highlights the type of risks and diseases that are associated with collection of biological evidences in laboratory settings. Moreover, the paper discusses the reasons due to which such risks can arise.

Introduction

Viruses and bacterium are a major source behind the diseases in humans and animals. With the enhanced research and development against many of the diseases, vaccines were developed which resulted in eradication of some diseases. Nevertheless remaining diseases are still haunting human beings. In this regard communicable diseases are the most dangerous as they have the ability to transfer from a person to another by various means. Some of the most common means they can adopt to enter into another body includes, blood, air, urine, food, or water. In that way despite of having numerous vaccines, risks related to certain diseases still prevail in the society. Several viruses pose great threat to the lives of an individual, for instance viruses like HIV/AIDS, Hepatitis, diarrhea, cholera, avian flu, Ebola, and several other can be fatal. All have the tendency to move from a person to another.

Despite of the efforts made by World Health Organization and various other bodies across the world, risks of catching a severe disease might have limited, but they are still present. The reason behind that are the sources through which these viruses transfer.

Diseases that are more familiarly known as water borne include diarrhea, measles, flu, Hepatitis A, Ebola, Anemia, Dengue, Malaria, Typhoid and similar other. The viruses and bacterium, which use air as the transmission mode usually, cause diseases such as, Anthrax, Chickenpox, Influenza, Measles, Smallpox, and Tuberculosis. Lastly, the diseases that are caused by blood transmission include HIV, hepatitis B, hepatitis C and viral hemorrhagic fevers. The diseases that are transmitted using blood are relatively more dangerous. They affect a person's health greatly and have major tendencies of being fatal.

Despite greater safety concerns and guidelines, these diseases are increasingly inflicting wounds on people belonging from different parts of the world. Surprisingly, one of the major reasons behind their transfers is laboratory testing and collections. In the current health settings across the world there so many safety guidelines, especially in laboratories, but still these ailments prevail.

Among the risks that are associated with laboratory testing, the one that is infrequently reported in lab technicians include Nisseria (Sejvar, 2005). In the year, 2000 there were around two cases in ...
