Patient: hi, I stay in Gurgaon, India for last four years. Last three years i have had typhoid every year in summers. Even this year what started as a normal sunstroke fever later was diagnosed as typhoid. This too when i have taken booster dose just two months back. Doctor: Hello Typhoid fever is a systemic  water born disease characterized by fever 7 abdominal pain and by dissemination of Salmonella typhi or paratyphi, for which humans are the only hosts .As you mentioned that you  have fever in every summers ( so this may be due to infected water).Take care about that ( water boiled , cooled or sterile water  to be used).Vaccinations are available as:Typhoid ty21, oral live attenuated 1 capsule every other day for 4 doses.Booster dose after 5 years .Typhoid Vi capsular polysaccharide , injectable (typhim ) 1 dose INTRAMUSCULAR .Booster dose after every 2 years.So this is a complete vaccination chart .The drug of choice in typhoid fever is ciprofloxacin 500 mg twice in day for 14 days .In few cases ceftrizone 2 gm for 7 days .Since all these are prescription drugs ,so consult your  doctor and take a  prescription.Good luck.
