Disease Information

Salmonellosis is a bacterial infection that affects the intestines and occasionally the bloodstream. It is one of the more common bacterial causes of diarrhea. Most cases of salmonellosis occur in the summer months and may occur as a single case, clusters or outbreaks. Typhoid fever is a life-threatening illness caused by the bacterium Salmonella serotype Typhi. There is no vaccine to prevent salmonellosis.


Common ways people get salmonellosis include eating raw or undercooked food (meat, poultry, eggs) or through contact with reptiles, poultry or their droppings.
