What Is Typhoid Fever?

Typhoid fever is an infection caused by the bacteria Salmonella typhi. This germ affects the intestinal tract and the bloodstream. It is an acute illness associated with fever caused by the bacterium Salmonella enterica serotype Typhi. It can also be caused by Salmonella paratyphi, a related bacterium that generally causes less serious illness. The bacteria are deposited in water or food by a human carrier and then spread to other people in the area.

The incidence of typhoid fever in the United States has declined markedly since the early 1900s when tens of thousands of cases were reported in the United States. Mexico and South America. This improvement is the result of better environmental sanitation. India, Pakistan, and Egypt are also known as high-risk areas for developing this disease. Worldwide, typhoid fever affects more than 21 million people annually, and about 200,000 people die from the disease.

How Can You Know If You Have Typhoid Fever?
