Thank you for your query. Typhoid fever is an enteric (intestinal) fever that is caused by salmonella typhi/paratyphi. This usually starts as high fever (102- 104F)which may be associated or progress with gastric (stomach), intestinal symptoms, pulmonary (lung) and systemic( whole body) symptoms. Loose stools, abdominal pain, bloating, lung infections, sepsis (overwhelming infection that spreads to the blood) may occur. The reliability of the stool and blood test depends on when , during the course of the illness, the tests were done. This can be concluded based on a detailed medical history, recent travel history and risk factors. Based on your query, you seem to have taken the blood test too soon (first week) to show an accurate titre. The H agglutinin titre (negative for you- positive if it is 1:200 titre )is more reliable than the o agglutinin titre to support the diagnosis of Typhoid. however, it is possible that you may be a carrier (stool test shows bacteria- unspecific) To address your concern, severity is based on clinical manifestations and extent of disease rather than lab results You seem to be having a mild diarrhoeal illness which is self limiting. Currently diet restrictions include oily and spicy food. Avoid junk food , carbonated and sugary drinks. Have as much fresh fruits and vegetables as you can. Remember to wash them and cook it well. While travelling, you could also peel the skin of the fruits to prevent a possible infection. Hard boil the eggs and cook meat till fully done. If your symptoms persist, please visit your doctor , who may decide to prescribe appropriate antibiotics. I strongly urge you to avoid self medication, especially with antibiotics and once you start on them make sure you complete the full course (even if you feel better). This prevents drug resistance (over all and in your own body). Hope this helps. Wish you good health Please feel free to contact us should you require further clarification
