In simple words: Paratyphoid fever is an infection caused by the Salmonella paratyphi bacteria, usually spread through contaminated food or water. It's similar to typhoid fever but less severe. Symptoms include high fever, stomach pains, headache, and loss of appetite.Sometimes, rose-colored spots appear on the skin.Diagnosis is confirmed by testing stool samples. Treatment involves antibiotics, and vaccination is recommended for travelers to areas with poor sanitation.

The bacterium Salmonella paratyphi, typically spread through contaminated water and food, causes paratyphoid fever, an infection that affects the gastrointestinal system and is less severe than typhoid fever. The specific type or subtype of the causative bacterium is not documented.

Example 1: A patient presents with high fever, abdominal pain, headache, and loss of appetite after returning from a trip to a region with known poor sanitation. Stool cultures confirm Salmonella paratyphi, and the patient is diagnosed with paratyphoid fever, unspecified (A01.4)., A patient experiences persistent fever, malaise, and diarrhea.Blood tests and stool cultures are performed, and Salmonella paratyphi is identified, but serotyping is unavailable.The physician diagnoses paratyphoid fever, unspecified (A01.4), and prescribes appropriate antibiotic therapy., An individual presents with symptoms suggestive of enteric fever, including fever, headache, and abdominal discomfort.Laboratory tests are inconclusive for specific Salmonella serotypes.Due to the lack of definitive subtyping, the diagnosis is coded as paratyphoid fever, unspecified (A01.4).

Documentation should include signs and symptoms, laboratory results confirming Salmonella paratyphi (if available), and any associated complications. If the specific serotype (A, B, or C) is identified, the more specific code should be used.
