Salmonellosis, or salmonella, is one of the most common foodborne diseases. Overall, salmonella infections are decreasing in the United States, but some types are still increasing.
Salmonella may occur in small, contained outbreaks in the general population or in large outbreaks in hospitals, restaurants, or institutions housing children or the elderly. While the disease is found worldwide, health experts most often report cases in North America and Europe. Every year, the Centers for Disease Control and Prevention (CDC) receives reports of 40,000 cases of salmonellosis in the United States.
People with AIDS are particularly vulnerable to salmonellosis, often suffering from recurring episodes.
