the epidemiologic triad. According to the epidemiologic triad, there are three factors that influence the occurrence of disease: Etiologic agent
Host factors, Environmental factors.
Describe each of these factors for a Salmonella foodborne outbreak. ,What are some of the host factors that can influence the occurrence of a disease?,

Salmonellosis is an infection caused by salmonella type of bacteria.. The most common
symptoms of salmonella include diarrhea, vomiting, fever and abdominal crumps. Research
shows that salmonella is the leading cause of diarrhea globally. Salmonella infection is broadly
categorized into two species, salmonella bongori and salmonella enterica. Mostly, salmonella
infection is spread by the intake of contaminated foods such milk, eggs and meat and contact
with human or animal wastes. This paper attempts to explain how etiologic agent, host factors
and environmental factors influence the occurrence of salmonella foodborne outbreak. Albeit
salmonellosis is a dangerous infection, it can be avoided through many simple ways. the epidemiologic triad

The Health and Environment Linkages Initiative (HELI), which operates under the auspices of the World Health Organization (WHO) and the United Nations Environment Programme (UNEP), was primarily established to educate policymakers in developing countries about the various environmental threats to public health. Notably, WHO reports that approximately 25% of all diseases globally stem from environmental factors. Therefore, understanding these linkages becomes crucial in addressing public health challenges, as highlighted by the epidemiologic triad.

Furthermore, the epidemiologic triad provides a framework that illustrates the complex interactions between the etiological agent, host factors, and environmental influences. This framework is essential for comprehending how environmental conditions can exacerbate health issues and disease transmission.

In conclusion, it is imperative to support these assertions with substantial evidence from the literature, which underscores the importance of addressing environmental health challenges in conjunction with epidemiological principles.
