The Effects of Zoonotic Diseases
Case Study #13

April 17, 2011

Zoonosis refers to an infectious disease in animals that can be transmitted to people. An animal serves as the natural reservoir for such an infectious agent, ("MedTerms," 2001). Many zoonoses, which is simply the plural meaning of zoonosis, including viruses, bacteria, and parasites can be transmitted to humans by various routes. Some of these routes consist of animal bites, vectors (i.e., insects), and animal-to-human contact (i.e., inhalation of respiratory droplets or skin-to-skin contact), (Bauman 613-14) & ("Infectious Diseases," 2009). Most emerging infections that have occurred world wide are said to be a zoonotic disease. Many of these diseases are fatal or have the potential to be fatal if not treated quickly and properly identified. An example of a zoonosis case that has the potential to arise annually is listed below:
Case Study#13
“You work in a small family practice in rural VA. A man in his early 50’s comes in with a complaint of intermittent fever (102-103°F) and headache for the past two weeks. The physician examines him and takes a history. The only clinical finding is a wound about the size of a quarter on his right thumb. Axillary lymph nodes are swollen and tender. The man says he cut himself while skinning a rabbit three days ago. On the basis of these observations the physician prescribes streptomycin and asks the man to call if his symptoms don’t improve in three days.
The physician makes a request for blood to be drawn and then informs the patient to return in four weeks for another blood sample. She says there is no need to culture the wound.”

Based on the given information from this Case Study, at first glance I thought that it could be two different diseases causing this man’s illness: Francisella tularensis and Yersinia

The framework allows for an understanding of the cross-sector economic influence of zoonoses using improved risk analysis and listing a range of analytical tools. The goal of the framework is to link the check outputs of animal and human disease transmission models, economic influence models and assessment of risk management options to gain improved understanding of factors affecting the acceptance of risk management plans so that investment planning includes the most promising interventions (or sets of interventions in an integrated fashion). A more complete understanding of the costs of the disease and the costs and benefits of control measures would promote broader application of the most efficient and effective control...

Zoonotic Diseases

...Introduction Zoonotic diseases are infectious diseases which can be transmitted from animals to man. Due to frequent contact and domestication of wildlife animals, zoonotic diseases are increasingly becoming more prevalent. Public parks and gardens are home to abundant populations of birds. One of the most frequent species known to thrive in such areas are feral pigeon (Columba livia). Although there are few reports of disease transmission between pigeons and humans, their close interaction with humans and ability to carry zoonotic pathogens make them a public health risk. In fact, these birds are present at very high densities (2,000 individuals per km2) and can cover a maximum distance of 5.29 km (Dickx et al., 2010). This may result in the increase risk of pathogen transmission among other birds and potentially to humans. Studies have shown that most infected pigeons do not show signs of clinical disease. These birds may therefore pose a public health risk to the human population. Pigeons, like many other bird species, can harbor diseases that can be zoonotic in nature. One of the pathogens most frequently carried by pigeons is Chlamydophila psittaci. C. psittaci is an obligate intracellular bacterium that causes a disease in birds known as Psittacosis or Avian Chlamydiosis. Psittacosis is highly contagious and often causes influenza-like symptoms, severe pneumonia and non-respiratory health problems. Birds can shed this bacterium in the environment when they are...

Dryvax Research Paper

...Smallpox, a disease caused by variola virus, has been globally eradicated since the early 1980s due to the massive vaccination program conducted by the World Health Organization. However, there are concerns that the smallpox virus could be used as a biological weapon. In addition, the monkeypox virus, which resembles the smallpox virus, is an emerging virus that caused an outbreak of human monkeypox in Africa, and more recently in the United States. Therefore, the need for protection against these zoonotic viral infections remains [1-3]. Variola belongs to the Orthopoxvirus genus, family Poxviridae, which also includes vaccinia, monkeypox, cowpox, and other viruses. Because the majority of orthopoxvirus DNA is highly conserved considerable cross-protection can be conferred, through infection or immunization, within this family of viruses. For example, variola virus shares >90% similarity with the vaccinia genome, which enabled eradication of smallpox using the vaccinia virus....

...3.1 in the stands next to you. You tell him that you are a paramedic and will walk him to your car where you have your medical equipment. He reports that he has had a headache off and on since he had a tooth extracted four days ago. This evening he is feeling very weak.  His blood pressure is normal. When you listen to his heart you note that he has a pronounced murmur. He reports having had rheumatic fever 15 years ago. You examine his fingernails and find one that has tiny petechial hemorrhages under it.  1. Name the most likely causative agent of this man's signs and symptoms.  2. Name the most likely infection this man has.  3. What type of culture would a physician most likely order, and why?  4. What is the treatment?  5. What is rheumatic fever? What causes it. Can it be prevented? 1) Streptococcus viridans transmitted through the wound to the bloodstream as a result of the tooth extraction.  2) subacute bacterial endocarditis (endocarditis- inflammation of the endocardium)  3) a blood culture looking for alpha hemolysis because Streptococcus viridans is alpha hemolytic and this would detect the presence of the bacteria in the blood.  5) Rheumatic fever was the cause of the man's heart murmur because the endocardium (lining of heart muscle that covers heart valve) was damaged. A damaged heart valve makes a person more susceptible to bacterial endocarditis because the bacteria easily lodges onto the heart valve. http://jan.ucc.nau.edu/~fpm/bio205/sp-05/cardiovascsyst3=1-8...

Antibiotics: Not Always the Answer

...went straight to my doctor, hoping it wasn't tonsillitis. The first thing we had to figure out was to see if this was a bacterial or viral infection. My tests results for strep throat, mononucleosis, tonsillitis, and blood samples to test for bacterial infection were all negative. My doctor reported that my results indicated that I had some sort of virus, and did not prescribe me antibiotics, raising questions for why I shouldn't be taking antibiotics for my infection. Since Alexander Fleming's discovery of them in 1927, antibiotics have played a profound role in ridding the population of bacterial infections. Antibiotics are chemicals that work to kill disease-causing, single-cell living organisms called bacteria ("The Danger of Antibiotic Overuse"). Bacteria can surpass our immune system, reproduce, and cause diseases or infection by producing chemicals that damage our bodies ("What Are Antibiotics? How Do Antibiotics Work?"). For instance, bacteria can invade our inner ear and cause a bacterial ear infection. Our immune system works to fight the bacteria, resulting in inflammation. However, the immune system sometimes is not able to activate itself quickly enough to outpace the reproductive rate of a certain bacterium. Antibiotics are used as an alternative and helpful method to help our immune system kill the bacteria and reduce inflammation. Many antibiotics interrupt the machinery inside bacterial cells that build the bacterial cell...

Climate Change In The Anthropocene Era

...Health is often defined as complete physical, social, and mental wellbeing; not only the absence of sickness. It is shown that the effects of climate change in the Anthropocene era have an impact on all aspects of human health. While illness and disease are constant elements of human existence, the causes and ways in which they are treated is constantly evolving. Using an ecological framework to examine human sickness and health reminds us that there is no sole cause of either—and that public health is impacted by many—often interacting—elements on both the individual and global level. Professor Monica White defines the Anthropocene as the “current geological period where human activity has been the dominant influence on climate and environment” (White 2/1/2018). The changing climate of the Anthropocene era plays a large role in impacting human health and disease-- from disease outbreaks to natural disasters the effects of climate change have a monumental impact on sickness and health. As an example, the raising global temperatures cause mosquitos to become...

Larry Bassman Food Borne Illnesses Alexa Glisson SCI/ 163 November 21, 2012 Giardia When generally thinking of parasites and food-borne illnesses, we tend to think about the poorest and dirtiest places on Earth. In reality, parasites can be found almost anywhere on this planet. One type of common food-borne illness is giardiasis or a giardia infection. This infection is in the intestine and caused by microscopic giardia parasites. The given the opportunity this vicious creature will infect anybody regardless of sex, age, living conditions, and body types. Surprisingly this is a zoonotic disease affecting not only humans but also domestic and wild mammals. There are several ways a person can contract this illness. The most common way to contract the illness is ingesting water that has been contaminated with animal feces. This is the reason we are constantly reminded never to drink water from a lake or stream that have not been purified. Given that many of undeveloped countries have little or no clean water, the majority of the cases of giardiasis affect children and adults in these third world countries. A person can also get infected by eating raw or undercooked contaminated food, touching something that has feces on it from a day care or nursing home environments, and unprotected anal intercourse. Once this parasite has found a home inside someone or something’s...

Factory Farming Research Paper

...However, this is often not enough. (Schlosser, 169) According to Lucas Spangher an environmental scientist for Huffington Post, “Workers in the meat industry make an average of $23,000 a year, work 10+ hours a day, are pushed so hard they often defecate in their pants to avoid slowing down and suffer a repetitive motion injury rate 30 times the national average. This statistic misses out on the harassment and abuse that workers face from superiors. Although the exact number is unknown, it is estimated that 38 percent of all factory farm workers are from outside the U.S. and have an undocumented status.” This tarnished environment has a large effect on employees. Not only are workers abused by leaders in the workplace, but also become easily susceptible to zoonotic diseases: diseases that are able to pass from animal to human. These diseases, such as Swine Flu and Avian Flu can be fatal to humans. Not to mention, bacteria in the workplace like E. Coli and salmonella can contaminate the food supply, harm consumers, and those in the workplace. The food industry has little to no decency, respect, or consideration for their employees. Similar to workers, America’s crops and animals haven’t been treated kindly. When first created, McDonald’s was only buying potatoes from few family owned farms. However, Ray Kroc, the founder and owner of the golden arches decided these purchases weren’t efficient enough. Realizing that potatoes’ shape, size, and taste are directly related to their environment...

Opinion Essay

...biological common ground we share with other species. The SARS virus probably crossed over from animals to humans in Guangdong Province in China. Humans got monkeypox from pet prairie dogs, which probably caught it, in turn, from an imported Gambian rat. Meanwhile, at the movies, there is ''28 Days Later,'' a horror film about a ''rage'' virus that passes swiftly and catastrophically from chimpanzees to humans. We can probably discount the dangers of a fast-acting horror-movie virus, but not the others. If nothing else, the emergence of SARS and the recent outbreak of monkeypox in the United States are reminders that the potential biological effects of globalization can be chilling. Ordinarily, prairie dogs, native to America, do not catch diseases from rats native to western and central Africa. And humans do not ordinarily catch diseases from prairie dogs. What made the chain of monkeypox infection possible were humans who keep wild animals -- prairie dogs and Gambian rats -- as pets. Although the federal government has now banned the distribution of prairie dogs and the importation of rodents from Africa, the monkeypox scare demonstrates how poorly regulated the ownership of and traffic in wild or exotic pets really are. A dozen states and some localities outlaw owning dangerous animals, and the federal government, as a signatory to the Convention on International Trade in Endangered Species, prohibits, in most cases, owning or transporting endangered animals. But that still...

For each element, name a specific disease and discuss the change associated with its outbreak, change or emergence as a public health phenomenon. Answer: There are four elements including (1)human population (2)pathogen (3)reservoir and (4)vectors. The dynamics of diseases depends on the overlap of niches of these elements. 1. Human population : Disease patterns and processes reflect interactions of individuals within populations. Many diseases such as lung cancer or pulmonary diseases emerge as increasing urbanization results in higher air pollution. 2.Pathogen : Such as chloroquine resistance in malaria Parasites, the microorganism presents drug-resistant due to frequent mutation in response to antibiotic/drug treatment. 3.Reservoir : Rabies outbreaks are related to concurrent increased human activity that contact with animals. Rabies is a zoonotic disease that is caused by a virus. The disease infects domestic and wild animals, and is spread to people through close contact with infected saliva via bites or scratches. 4.Vectors : Japanese encephalitis is a disease transmitted via mosquitoes from Domestic pigs and wild birds. The outbreak occurred when the vector mosquitoes proliferated in rustic countries in summer. The widespread use of vaccine and cleaning living environment can control of the disease. ...

Health in Tropics

...1950 and 2010 the gap between life expectancy in the Tropics and the Rest of the World has narrowed. Over this period life expectancy in the Tropics increased by 22.8 years to 64.4 years and infant mortality reduced by 36%. The rate of change of mortality and morbidity has increased over the last two decades influenced by a range of different factors. Underlying life expectancy data are aggregated data, collected by the WHO to document the changing patterns of mortality. Table E3.1 provides the top ten causes of mortality in rank order over the last decade. Non-communicable diseases (NCDs) accounted for two-thirds of global deaths in 2011 and infectious diseases for one-third. In 2000 the relative proportions were 60% NCDs and 40% infectious diseases. This rapid shift reflects the massive scale up in recent efforts to prevent and treat a number of major infectious diseases. Although improvements in maternal and child mortality have been made these still remain unacceptably high. In 2011, 6.9 million children under the age of five died, 99% of these in low and middle income countries. Malaria, despite the enormous scale up in control activities still accounted for 14% of the under-five mortality in the Tropics. There are differences in the age at which mortality occurs stratified by income. In high income countries 70% of deaths occur in the over 70s and only one in 100 occurs in an individual under 15 years of age. In low income countries 40%...
