Doctor: Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.  You might have sub clinical typhoid fever. It is nothing but a variant of typhoid fever where the symptoms are minimal. You can take appropriate antibiotics according to protocol to tackle the illness. The complications are less in sub clinical conditions.  Hope I have answered your query.   Wishing you good health.  Thanks.
