Foodborne Illness Short Answer Questions Free Essays

Complete answers to questions below: What is the infectious agent (pathogen) that causes this infectious disease? For example, the name of the bacteria, virus, or parasite. The process of infection can be broken down into stages, each of which can be blocked by different defense mechanisms. In the first stage, a new host is exposed to infectious particles shed by an infected individual. We will write a custom essay sample on Foodborne Illness Short Answer Questions or any similar topic only for you Order Now The number, route, mode of transmission, and stability of an infectious agent outside the host determines its infectivity. Some pathogens, such as anthrax, are spread by spores that are highly resistant to heat and drying, while others, such as the human immunodeficiency virus (HIV), are spread only by the exchange of bodily fluids or tissues because they are unable to survive as infectious agents outside the body. How is this infectious agent transmitted through food or water? Infectious pathogens include some viruses, bacteria, fungi, protozoa, multicellular parasites, and aberrant proteins known as prions. These pathogens are the cause of disease epidemics, in the sense that without the pathogen, no infectious epidemic occurs. The term infectivity describes the ability of an organism to enter, survive and multiply in the host, while the infectiousness of a disease indicates the comparative ease with which the disease is transmitted to other hosts. Transmission of pathogen can occur in various ways including physical contact, contaminated food, body fluids, objects, airborne inhalation, or through vector organisms What is an example of a real life outbreak of this foodborne illness in the United States? In early October 2012, the Clark County Public Health Department (â€Å"the health department†) received the first reports of a cluster of Salmonella Virchow infections occurring in the county. Additional reports came in rapidly, and by October 9, interviews of ill persons indicated that the source of the developing outbreak was the On the Border restaurant in Vancouver, Washington. On October 9, On the Border temporarily ceased operation. Dr. Alan Melnick, Clark County Health Officer, stated that the closure was â€Å"a further precaution to reduce the risk of Salmonella spreading to others. Meanwhile, health department staff continued to interview employees and patrons of the restaurant to learn more about the precise cause of the outbreak. The health department also continued its work with On the Border employees to make sure that standard control measures—e. g. hand-washing and environmental sanitation—were in place and effective, so that when the restaurant resumed operation it would not pose a continuing threat to the health of its patrons. As of the date of the restaurant’s closure on October 9, there were 11 confirmed and five probable cases of Salmonella Virchow infection linked to the consumption of food at the restaurant.  · What are the clinical symptoms, duration of the disease, and treatment if any?

Ten Characteristics of a Good Teacher free essay sample

The ten characteristics There is a line in Saint-Exuperys The Little Prince that applies to any endeavor, but especially teaching. It reads: That which is essential cannot be seen with the eye. Only with the heart can one know it rightly. The essence of teaching Is difficult to qualify, but that line leads directly Into my most essential criterion. 1. I want a teacher who has a contagious en husiasm for his t teaching†one who, as Rich rd Via says, loves his Stua dents and his work. Mr. Via is an educational specialist in using drama techniques to teach EFL at the Eastwest Center in Hawaii. I was fortunate enough to attend his teacher-training seminar in Korea In 1976. It was a pleasure to be In his audience. HIS enjoyment in transmitting knowledge and participating In the seminar was apparent and infectious. His passion for teaching instilled a passion for learning in all the participants. We will write a custom essay sample on Ten Characteristics of a Good Teacher or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page For me, the most crucial factors in effective teaching are who the teacher is and how he acts in the classroom. This influences the way the stu ents react d toward the target language and, therefore, their success in learning it. 2. I want a teacher who is creative. Teaching must be more han simply opening a book, doing exercises, and following an outline written by someone else. In the tedium of repetition, the student can go through the motions of doing the exercises without his mind being engaged. What can a teacher do to engage the students mind? There are a myriad of techniques that the creative teach r can employ† information-gap exercises, e games, songs, Jazz chants, problem solving, and other techniques that allow the student to utilize the skills he has already developed in his first language. 3. I want a teacher who can add pace and humor to the class. The humor of one of my teachers had the effect of alleviating my nervousness†of reducing my affective filter. There was a rapport among the students and the teacher because we were all laughing together. We had a good time learning, and we made a lot of progress because we were not afraid to make mistakes; we could take chances. As Krashen would say, the affective filters of the students were low, facilitating acquisition. Another teacher that I had maintained an excellent pace in the class. She never lost an instant consulting a list or thinking about what to do next; she had prepared Ђâ€ that was evident†and she was going to capitalize on every second. I was somewhat nervous in her class, but I didnt have time to worry about it because events moved so quickly. I was literally sitting on the edge of my seat so that I wouldnt miss anything, and my adrenalin was a positive force. I should add that humor is a double-edged sword: it can backfire, for what is funny to one person may not be funny to another. Humor across cultures can add a layer of difficulty to communication. 4. I want a teacher who challenges me. I had several teachers who always spoke to me in Spanish, both in and out of class. I felt they were showing confidence in me and chal enging me to speak Spanish. The students passive knowledge of the target language is always greater than his active knowledge. There is no reason why a teacher should use any language other than the target language except possibly for purposes of expediency. When a teacher reverts to the native language, he is showing a Number nglls e aching o rum lack of patience with the students struggles in the target language. In addition, switching codes is confusing. I was given a test in which all the in tructions were read to me s n English, so that I would be sure to understand every thing. Then I had to answer in Spanish. But the test had three parts and I had to continue switching codes back and forth from En 1ish to Spanish; I found this very confus ng. It is like going Offa diet†once you cheat a little, then you want to cheat a little more. If someone speaks to me in English, this activates my English channel and I am prepared to think in English. Speaking in the target language to the learner prepares and challenges him to speak in that language.
