Salmonellosis is a very common infection of the gastrointestinal tract caused by a bacterium called Salmonella. People infected with Salmonella develop gastroenteritis. The great majority of cases (>90%) will have diarrhoea; a majority will also have headache, fever and tummy cramps. Bloody diarrhoea is also not uncommon. Symptoms usually develop within 6‐72 hours following infection (generally 12‐36 hours). The illness usually lasts 4 to 7 days, and most people recover without treatment.
