the epidemiologic triad. According to the epidemiologic triad, there are three factors that influence the occurrence of disease: Etiologic agent

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

Health and Environment Linkages Initiative (HELI) is a function of World health
