Does Salmonella infection spread through kiss or sex?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

I have only diarrhea. If I have Salmonella then how long will it last? Can I kiss or have sex? Could it be on the blood?

Hello,

Welcome to icliniq.com. There are two types of Salmonella. Both types can spread through feco-oral route. Which type do you have? If you have Salmonella Typhi then you would need treatment. If you have Salmonella paratyphi (only diarrhea) you may spontaneously recover. In either case I would suggest precautions for a month after you were diagnosed with the infection. The bacteria may stay in body secretions but none of them spreads through saliva or semen or vaginal secretions. Please share more information so that I can generate a better plan of care.
