Paratyphoid fever: symptoms, treatment and prevention

Symptoms may build gradually and can include fever, headache, weakness, abdominal discomfort, diarrhoea or constipation, and reduced appetite. A fever has many possible causes, so symptoms alone cannot confirm paratyphoid fever. Recent travel, unsafe water or food, and contact with someone carrying the infection are useful details for a clinician.

Testing may involve blood or stool samples. If paratyphoid is suspected, treatment is chosen by a clinician because antibiotic resistance and individual health factors can affect the medicine selected. Conditions such as common cold, COVID-19, or chickenpox need different approaches.

Arrange medical review for a persistent fever, particularly after travel or a possible food or water exposure. Rest, take frequent sips of suitable fluids, and use only fever medicines that are appropriate for you. If antibiotics are prescribed, follow the instructions and finish the course unless the prescriber changes it.

Wash hands thoroughly after using the toilet and before handling food. Avoid preparing food for other people until a clinician confirms it is safe. Tell the healthcare team about travel, medicines, allergies, and any household members with similar symptoms.

Seek urgent help for confusion, fainting, severe abdominal pain, repeated vomiting, blood in stool, breathing difficulty, or inability to drink. Children, pregnant people, older adults, and people with long-term illnesses may need prompt assessment when fever and fluid loss occur together.

Ask which tests are needed, when results are expected, which treatment is suitable, how to reduce spread at home, and what symptoms should trigger urgent review. Ask when you can safely return to work, school, or food preparation.
