What Is Salmonella?

Salmonella is a bacteria that can lead to salmonellosis, an illness that causes diarrhea, fever and stomach cramps some 12 to 72 hours after exposure. Most cases last around a week, but some can be deadly. When people develop severe diarrhea, the infection can migrate from the intestines and travel around the body in the bloodstream. Without antibiotics, such cases can be fatal. Footage Credit: Videoblocks, Pixabay, Getty ImagesMusic Credit: Audioblocks 'Medical Mystery'
