Salmonella infections usually do not have sequelae after active treatment. However, if the treatment is not timely, sequelae such as intestinal perforation, intestinal hemorrhage, hepatosplenomegaly, etc. may occur. Salmonella is a foodborne pathogen of the Enterobacteriaceae family, which is usually infected by consuming contaminated food (e.g. meat, milk, etc.). After infection, patients mainly present with symptoms such as fever, nausea and vomiting, abdominal pain and diarrhea. Salmonella responds well to antibiotics and usually has a good prognosis after aggressive treatment, usually leaving no sequelae. However, if the patient is not treated in time, complications such as renal failure, pneumonia, myocardial infarction, etc. may lead to sequelae, such as organ damage, intestinal perforation, intestinal hemorrhage, liver and spleen enlargement. Patients with Salmonella infection are advised to seek timely medical attention and actively receive treatment to avoid delaying the condition leading to sequelae.
