Salmonellosis is an infection caused by Salmonella bacteria. Most people infected with Salmonella develop diarrhea, fever, vomiting, and abdominal cramps 12 to 72 hours after infection. In some cases, the diarrhea may be so severe that the patient becomes dangerously dehydrated and must be hospitalized.Symptoms of salmonellosis include diarrhea, fever, and abdominal cramps. They develop 12 to 72 hours after infection, and the illness usually lasts 4 to 7 days.
Salmonellosis is diagnosed based on a medical history and a physical exam. A stool culture and blood tests may be done to confirm the diagnosis. Most people don't need to seek medical attention for a salmonella infection because it clears up on its own within a few days. However, in cases involving infants, young children, and older or immunocompromised adults, is associated with high fever or bloody stools, or appears to be causing dehydration.
The epidemiological progression of human salmonellosis in Norway is parallel to trends noted elsewhere in Europe. During the past two decades, the number of reported cases has increased steadily, with a special sharp rise in the early 1980s due to the emergence of Salmonella enteritidis, followed by a levelling off in recent years.
The National Salmonella and E. Coli Centres are involved in identifying and typing Salmonella spp. and E. coli from within India and around the world.
