Hi, thank you for asking Healthcare Magic.
I have gone through your query and understood your worries.
If I were your treating doctor, I would place you on Ciprofloxacin
tablets for 10 days. Also, given that the germ is transmitted by contaminated food or water, I often educate my patients on personal hygiene e.g washing of hands after defecation and sexual contact, before preparing or eating food and to avoid drinking water or eating food from doubtful sources.
I hope I have answered your query
I wish you good health
