Principles of Epidemiology and Outbreak Investigation

Salmonella in the Caribbean IHP-330-X6659 Principles of Epidemiology Southern New Hampshire University Julie Bytnar August 14th, 2022 Salmonella in the Caribbean had an outbreak in the mid 1980's that affected thousands of residents and tourists. When this event took place in the 80's and 90's it did not get the attention that was needed to stop the outbreak at the time. People visiting and living on the island had gotten sick with a bad case of diarrhea and GI issues. These cases flagged an investigation to see what may be causing the outbreak with so many people affected. Bacterial strains of salmonella found were Enteritidis, Typhimurium, and more. Needing to take a step into controlling the outbreak researchers needed to figure out where, when, who and how the outbreak had occurred. In this study, everyone who had reported their symptoms and illness all came into contact with the same issue, they all had raw or undercooked eggs. In the surrounding area, six out of ten farms did not handle their eggs to sanitation guidelines. This issue was found while under investigation. The age group who this issue affected the most was children ages 0-4 years and age 5-9. In the research that is available, it seems that the year 1996 was the worst in the outbreak. In the months of February to mid-April had most cases in this year and then spiking back up during the winter months. Research assumed the spike was due to the holidays. The agriculture industry had to approve new sanitation strategies to help stop an outbreak like this from happening again. The concerns of taking potential sales and income away from the island are a concern for locals who work in the tourist industry and also farming. Social and behavioral determinants that are strongly linked to the public health issue in the research of the salmonella outbreak in the Caribbean are the lack of education and training. socioeconomic statuses, and whether they were island residents. These are all delays that caused the stopping of the outbreak. It was hard for professionals to keep track at first because of the islands being such a high tourist location. Island residents not having access to healthcare because of their social economics. Either they needed to attend work to provide income for their family, or they could not afford to seek healthcare for their symptoms. Both which could potentially spread the illness. The lack of knowledge of what was happening and how it was being spread delayed the stopping of the outbreak. All of these issues were beyond dangerous for an island that lives solely from tourism. One disparity that took place in this area of the Caribbean was the lack of education of sanitation. The farmers not having the knowledge of safely attending to their flocks after gathering their produce put all of the vendors and consumers at risk. In the article, it has a mention of the unsanitary conditions the flocks were kept in. The second dispari
