hi A warm greetings to hcm Can you tell how was it diagnosed, clinically or by blood culture or widal or any other test? Widal is not a very good test in endemic country like India. If at all, it is typhoid, there is chance that it is a quinolone resistant strain, which is of course, not uncommon in India. Go to a doctor practising infectious diseases and get evaluated for other possibilities of fever, If you continue to develop fever. It can be just a viral fever or a heat stroke because you have a history of exertion. your evaluations may include some other lab evaluations also. In typhoid, the common antibiotic practice in India is Oral cefixime as the first line drug. Take plenty of water with added electrolytes. All the best.
