Typhoid Treatment
Ciprofloxacin 500mg is the drug of choice for the treatment of typhoid. Chloramphenicol 500mg four times daily, ampicillin 750mg four times daily and cotrimazole 2 tablets twice daily are also used but most of the cases are resistant. Azithromycin 500mg once daily for 14 days is used in ciprofloxacin resistant cases. Pyrexia may persist for up to five days after the start of specific therapy.
Prevention
Living conditions and improved sanitation reduce the risk of getting the disease. Travelers to endemic countries should be inoculated with one of the three available typhoid vaccines (two inactivated injectable and one oral live attenuated).
