PUB-540-RS3-Oswego Outbreak Investigation Case Study Assignment

Part 2

In the epidemiological study, the outbreak of diseases depend on various factors. In other words, disease can be caused by different forms of infections that are either occurring naturally in the environment of manmade. Measuring the outbreak of diseases involves the collection and analysis of data to understand the risk factors. Data are always collected from the respondents on various possible causes of the disease outbreaks. There are different methods that can be applied in the process of data analysis to determine the accuracy of the data analysis outcomes. Contingency table is one of the best approach of analyzing and interpreting the cause of a disease (Aygören-Pürsün et al., 2018). Before engaging in the use of contingency table, there is always the need to determine the frequencies and to understand different aspects of the data for accurate outcomes (Carcillo et al., 2017). Investigation of the disease outbreaks involved different procedures which has to be successfully followed. Every step ought to be covered to ensure the accurate prediction can be made. In the above case, the first step involved in the disease outbreak is the identification of the possible. The second step involved the identification of the food products and the kinds of pathogens that cause that spread or the disease outbreak. The investigation processes should also involve the possible agents involved in the spread of the disease among the populations.

In the above case study, there was the analysis of disease outbreaks from the food products (Roche et al., 2015). Some of the food products that were presented include cabbage, Jello, mashed potatoes, cakes, coffee, milk, fruit salad etc. The data was collected at different dates and the respondent were asked whether they consumed the food product. The interview was a “Yes” or “No” answer.

From the analysis, there was the determination of the attack rate and the attack rate ratio. The outcomes were determined from the responses obtained from the clients. From the ratios obtained in the process of analysis, the above scenario meets the definition of a disease outbreak (Panisello et al., 2016). The contingency tables presented clearly summarize the relationship that exist between the categorical variables that have been presented. The variables have been shown simultaneously (Tomza?Marciniak et al., 2018). The steps required to investigate the disease outbreak involves the collection of data, which has already been presented in the Microsoft Excel. After the process of data collection, there was the determination or the calculation of risk ratios (Geng et al., 2017). The above computation was done for each of the food item presented in the table. The outcomes was presented in Oswego Line Listing Workbook. The frequencies presented in the table, Oswego Attack Rate Table was used to determine the attack rates and the attack rate ratios through the application of the Excel formulas (Saghafian et al. 2018). From the given risk ratios, there is a clear indication that the above criterion meets the definition of the disease (Kateri, 2015). The above steps aided in the investigation of the Oswego event through the presentation, analysis and interpretation of the data.

For each information to be successful, there was careful analysis and presentation of data. Also, the processes of data collection were accurate and this led to the successful outcomes. The disease outbreak was facilitate of a means of transmission (Saghafian et al., 2018). In this case, the rout of transmission was through ingestion of pathogenic organisms that came from the contaminated food (Kent et al., 2017). The food contamination is often attributed to the exudes or faces which are transmitted by different agents. In the above case study, the contaminated food was consumed which led to the transfer of the disease into the body which later caused outbreak.
