Typhoid fever from 20-25 days is really odd!!!!! Along with thrombocytopenia ( that is low platelet count) is also a rare feature. If fever persists , please do consult for a alternative diagnosis. If it is associated with oral ulcer, photosensitivity rash, joint pain then you need to visit a Rheumatologist. Do not go for a baby at this stage of illness.
Next Steps
Monitor symptoms and platelet count
