Infectious diseases

Topic B: New Diseases Throughout history, the emergence of infectious diseases has led to a proliferation of control treatments. Despite successful control methods, the recurring emergence of both new and old infectious diseases has preserved human mortality (Schrag & Wiener 1995, p. 319). It is the globalisation of such infections that traverse, the single appearance of a disease, to the entire world within a limited time span. The definition of emerging infections according to Schwartz and Yogev

INFECTIOUS DISEASE: TUBERCULOSIS Tuberculosis is one of the leading infectious diseases around the world. Globally, infectious diseases like tuberculosis among others continue to be one of the leading causes of death in children, adolescents and of the leading causes in adults (WHO). The purpose of this article is to examine and discuss mostly the etiology of tuberculosis, as well as its cause and spread. To better understand the subject of tuberculosis as an infectious disease and the problem it

The words “infectious disease” have been feared by humans from the time they were initially discovered and this fear continues to persist into the current status of the 21st century. This inherent fear stems from the ability of the tiny, pathogenic microorganisms responsible for these infectious diseases to wipe out thousands, or even millions from the human population. Though some may view infectious disease is an issue of the past, it still wreaks havoc in many of the worlds’ developing nations

Measles is an infectious disease that affects people worldwide. It is one of the most communicable infectious diseases, also known as Rubeola. It is considered to be a childhood illness but can affect people of all ages. In 1982, Department of Health Services set out to eradicate in the United States. The vaccine became available in 1963, after which cases in the United States dropped significantly. In third world countries, death rates are as high as 30%, the mode of transmission of measles is thru

were infectious diseases. More than half of all people dying in the United States died because of germs. Today, they account for a few percent of deaths at most. We owe much of that, of course, to antibiotics,” states Aaron Carroll a professor of pediatrics at Indiana University School of Medicine (Carroll). Now, once easily treated bacterial infections are increasingly difficult to treat and rid from a patient’s system because antibiotics can no longer effectively treat some common diseases. Antibiotics

The nature of infectious disease remains a far-reaching catalyst of poor public health. The inflation of new diseases, re-emergence of diseases and antimicrobial resistance to drugs is the result of changes in society and the microorganisms themselves (Cohen, 2000). The employment of drugs to prevent and combat disease often leads to drug resistance, as determined in the current antibiotic crisis. New ways of combating disease will and are being set up, such as the new budding theory of cross-reacting

assignment, I will be exploring the epidemiology of an infectious disease found on the Public Health Agency of Canada website known as Pertussis. This particular disease is also known as Whooping Cough due to the sound made while inhaling during a coughing spell. The information contained in this report will be taken from the Public Health Agency of Canada’s website which can be found at http://www.phac-aspc.gc.ca. SUMMARY ABOUT PERTUSSIS AGENT OF DISEASE Pertussis is caused by “bordetella pertussis” which

Neosporosis is an infectious disease prominent in both livestock and companion animals. Neosporosis was first discovered in dogs in Norway in 1984, when it caused neuromuscular degeneration that lead to hind limb paralysis. Due to the similarity of Neospora caninum to Toxoplasma gondii, neosporosis was misidentified as toxoplasmosis for many years. The two share similar life cycles and structure but vary when it comes to hosts. N. caninum thrives in cattle, dogs and related canids whereas T. gondii

Tetanus is an infectious disease that affects the central nervous system and characterized by a prolonged contraction of skeletal muscle fibers. It is also called lockjaw or trismus because one of the most common signs when infected is tightening of the jaw muscles. Most People think that tetanus is only caused by stepping on a rusty nail, but the real cause is contact with the bacterium called Clostridium tetani through wounds, cuts and scratches. It is typically found in soil, dust and feces but

suffering with this disease at present even though there is vaccine widely available, there is still a high morbidity rate in some countries every year. Africa, Western and Southeast Asia are the most affected areas, making approximately 86 percent of tuberculosis cases in the world. This research paper will discuss, tuberculosis in New Zealand. It will discuss the biology of the bacterium, risks factors and the importance of immunisation and prevention. Tuberculosis is an infectious disease caused by a
