Salmonella is a genus of rod-shaped, Gram-negative bacteria that commonly causes foodborne illness in humans and animals. There are over 2,500 serotypes, with Salmonella enterica being the most prevalent in causing infections.
Transmission typically occurs through consuming contaminated food or water, such as undercooked poultry, eggs, meat, or produce, as well as through contact with infected animals or their environments. The bacteria can survive in the intestines of healthy carriers, leading to fecal-oral spread.
Symptoms of salmonellosis usually appear 6 to 72 hours after infection and include diarrhea, fever, abdominal cramps, chills, headache, and nausea. In most cases, the illness lasts 4 to 7 days and resolves without treatment, but severe cases may require hospitalization, especially in young children, the elderly, or those with weakened immune systems.
Complications can arise, such as bacteremia (bacteria in the bloodstream) or reactive arthritis, though these are less common. Globally, Salmonella infections affect millions annually, with estimates from the World Health Organization indicating around 93.8 million cases of gastroenteritis and 155,000 deaths each year.
Prevention involves proper food handling, such as thorough cooking, avoiding cross-contamination, and maintaining good hygiene practices like handwashing. Vaccination is available for specific serotypes, such as typhoid fever caused by Salmonella Typhi, and is recommended for travelers to high-risk areas.
