Epidemiologic Investigation - Essay Example In the context of this project, the disease agent is a particular strain of E. coli that is well regarded as a food borne pathogen responsible for an infectious diarrheal disease. By definition, the characterization of the disease is intimately related to characterization of the agent that initiates or perpetuates the disease process. The E. coli talked about here is an enterotoxigenic strain of E. coli, which is a biological agent which exhibits certain host-related biological properties such as infectivity, pathogenicity, and virulence. Since an individual almost always contract a disease from his environment, when an epidemic of infectious disease occurs, the cause usually lies in the environment. Therefore, in any specific population, in order to be able to prevent outbreak of any disease state and to be able to intervene, the conditions prevailing any health-related event or state can be investigated, and appropriate measures can be taken to apply the findings of such studies for controlling the health problems preemptively. FoodNet or the Food Borne Diseases Active Surveillance Network was developed by CDC in the Emerging Infections Program. In this program, data are collected 10 US states in relation to the disease burden caused by Escherichia coli 0157:H7 strains that are known to be transmitted through food. This program quantifies and monitors the incidence of these infections by conducting active surveillance for laboratory-diagnosed illness. This epidemiologic event has great implications in public health. From the epidemiologic point of view, this is important since FoodNet quantifies and monitors these infections by conducting active population-based surveillance for laboratory-confirmed illness. The epidemiologic methods are used as surveillance tools, and these essentially scrutinize continuously the factors that would have determined the occurrence and distribution of this disease to be able to effectively control and prevent the disease. These essentially include collection, analysis, inter pretation, and distribution of relevant data for action. Escherichia coli is an emerging cause of food borne illness in the United States. Although most of these illnesses are mild, severe infections and serious life-threatening infections do occur. This has posed challenges to public health and public health administrations since there is change in the newly identified strains of the pathogens. With that, novel vehicles of transmission, changes in food production, and an apparent decline in food safety awareness might have aggravated the problems leading to these illnesses. There are several types of national surveillance systems for diseases that are food borne. These epidemiologic tools include outbreak surveillance, passive laboratory based surveillance, and active surveillance. Communicable diseases may be transmitted from the reservoir or the source of infection to the susceptible individuals in many different ways depending on the infectious agent, portal of entry, and the local ecological conditions. It is important to note that mu ch of the data about the vehicles and modes of transmission of these food borne diseases come from epidemiologic investigations of the outbreaks. From the public health point of view, the

Issues Faced by Operations Managers Essay Example | Topics and Well Written Essays - 1250 words

Issues Faced by Operations Managers - Essay Example Shortage of funds in financial market can create a problem for managers because supply of money in company leads to different financial activities. Continuous supply is very important for any company to operate. Managers also need to know that what their competitors are doing in the industry. They can't ignore competition around them in this dynamic world. Managers need to be informed that what they are doing in terms of Product development, Pricing, Marketing strategies and many more things. Any type of activity that the competitors do can create lots of problem for the managers. Every organization has an aim to be Global. Managers need to face many difficult situations when they are in foreign countries. They need to tackle certain factors for success when they are abroad. That includes Legal/Political Environment, Economic Environment and Cultural Environment. While going Global managers need to understand the Political and Legal uncertainties in the country they are doing their business. They should be aware of the Specific Legal laws of that country because if they don't know the Legal procedures of that country it can create many problems for them. Many countries have a history of unstable governments therefore managers face dramatically greater uncertainty as a result of political instability. For example the goal of one government is to nationalize the important sectors of the country where as the goal of the other government is to have free enterprises to promote free market economy. Economic environment can also affect manager's decision. The three most important factors in affecting manager decision are Fluctuating currency exchange rates, Inflation Rate and Tax policies. If the country has a high inflation rate in which they are operating can result in high productivity cost which can ultimately decrease their profits. Tax policies are the most concerning for managers. If tax policies are restrictive managers can face challenging situations. Managers need exact information of tax rules so that they can overcome with all the tax obligations.Managers also need to understand the culture of the country in which they are operating. Different countries have different cultures and managers must know they difference of each culture. This is very important factor for managers to take care of, because if they fail to understand the cultural values of that country they can't serve their products and services to the people of that country. For example if a company who is manufacturing Alcohol and is operating in USA and then they open a branch of their company in Saudia Arabia, But as Saudia Arabia is an Islamic State they can't sell the Alcohol in that country because they cultural and religious values doesn't allow them to drink, that can create huge problem for the managers of that company. SOCIAL RESPONSIBILITY: Today's organizations are moving towards social responsibility. Managers have to be careful while going for socially responsible because being socially responsi
