Typhoid fever is an acute illness associated with fever caused by the Salmonella typhi bacteria. It can also be caused by Salmonella paratyphi, a related bacterium that usually causes a less severe illness.The bacteria are deposited in water or food by a human carrier and are then spread to other people in the area.yphoid fever is contracted by drinking or eating the bacteria in contaminated food or water. People with acute illness can contaminate the surrounding water supply through stool, which contains a high concentration of the bacteria. Contamination of the water supply can, in turn, taint the food supply.
These bacteria are zoonotic, meaning they can infect both animals and humans. Salmonella is closely related to the Escherichia genus and are found worldwide in cold- and warm-blooded animals (including humans), and in the environment. They cause illnesses like typhoid fever, paratyphoid fever, and foodborne illness. Salmonella is also extremely dangerous, and weaker humans like the old and young could easily die from it. Salmonella can only be killed in food by cooking at high temperatures.
