SCI120 Research Project Number 25011100 11/29/2016 VACCINATIONS Throughout history, vaccinations have been used to help the prevention of infectious diseases; some of which can produce serious illnesses, crippling disabilities, and ultimately be the cause of death. There is evidence of ancient culture’s attempting to treat transmittable diseases with various forms of inoculations. Developments in the research of vaccinations increased during the mid-twentieth century because of the established
Infectious diseases are the result of a failed relationship between the parasite and the host. It’s the outline of the vectors of both agents and ranges in harshness from human rabies to the common cold. The improvements of vaccines, medicines, public services, and improved nutrition have helped decrease the amount of infectious diseases that causes death in our world. The advance in therapeutics and consequent alteration of the host defense mechanisms have had a huge increase on the incidence of
For thousands of years throughout history, humans have had to contend with the spread of infectious diseases. One of the greatest concerns in today’s society is the constant fear of a potential outbreak of an infectious disease. A disease for which society does not have a cure or vaccine available, thereby obliterating the human race if it were to spread. Notable cases include the emergence of HIV/AIDS in the 1970s and 1980s, and the more recent 2014 outbreak of Ebola in Western Africa. Examining
barrier is permeable, infections are able to transmit a disease in or through and cause serious or even fatal effects. There are different causes for the different categories of meningitis resulting in different symptoms and severities in each. One of the four different types of meningitis is bacterial meningitis. Neisseria meningitides is a bacterium that is seen to be the main cause of bacterial meningitis. There are multiple forms of this type of bacterium; therefore more than on strain exists of
This essay will explore the factors responsible for infectious disease; what it is, how it is spread, and what measures can be taken to prevent it. Microbes are single-cell organisms which are so small they can’t be seen with the unaided eye; but instead with a microscope. They are so minute that millions can fit onto the eye of a needle. Microbes date back billions of years and are the oldest form of life on this earth. They come in many forms: fungi, bacteria and viruses, and can live individually
becoming ill and/or dying due to infections and disease. Infections are constantly being spread and it is impossible to eliminate them one hundred percent. However, there are a variety of simple ways people can prevent them from further spreading. It is vital to educate young people about what infection is, how it is transmitted, and
It states that many diseases are caused by the presence of specific microorganisms within the body and that infectious diseases caused by infectious agents. It was a theory developed in the middle 1800’s, by Louis Pasteur, Robert Koch, and Joseph Lister. This theory still underlines contemporary bio-medicine. It’s responsible for the reduction in the numbers of infectious diseases. The development of the theory eliminated environmental, diet, and climate influence on disease. The germ theory is closely
Through studies of immunogenetics it has been demonstrated that our bodies respond obediently to infectious diseases by succumbing to their every need. This creates a situation where our genes as well as the environment around us influence our body 's own immune system (Genetic Control of Immune Response and Susceptibility to Infectious Diseases, 2013). The genetic variation within a number of many individuals causes natural selection to occur. With this natural selection we are susceptible to the
proportion of genetic variation between human populations (Fumagalli et al., 2011). Infectious agents including viruses, bacteria and protozoa are likely one of the strongest evolutionary drivers of the remaining genetic diversity within and between populations, as a result of the selective pressure they inflict in regions where infection is endemic. Mortality is the strongest selective pressure which is imposed by an infectious agent. Any genetic variant associated with an improved response to that pathogen
Diseases have been affecting the globe for decades. In recent years there have been many infectious diseases have been occurring and spreading across society. Out of the many infectious diseases, there are two that are going to be examined. The two diseases that are going to be analyzed and reviewed are Ebola and AIDS. The two diseases have a high rate of death among people who have been infected. The right rate of death has occurred for decades. Both of these diseases are highly effective at attacking
