Paratyphoid fever

Paratyphoid fever, also known as enteric fever, is a waterborne disease. It is caused by the bacterium Salmonella paratyphi. It is related to typhoid fever, but like typhoid, it is unrelated to typhus. Symptoms include:

• Fever,
• Abdominal pain
• Swelling of the liver or spleen
• Slow heart rate.

The disease is rarely fatal and people usually recover in a few days, but some people can carry the bacteria for months.
