48hr : After resolvement of diarrhea or other symptoms.

Depends: If you are intimate with the individual who has had c. Difficile colitis they may still be a stool carrier and have the potential to give it to you. If this is casual contact, transmission is not likely once the diarrhea has stopped. But continue washing hands and taking routine sanitary precautions.

Depends: Depends on if your symptoms totally resolve on the vancomycin. Generally 10 to 14 days. However some people are carriers and have no symptoms. Get a stool check when you feel better to answer this question totally.

Good question: Hard to say. We don't routinely test patients with c diff to confirm eradication after treatment, because they can still be asymptomatic carriers (test positive but feeling well). So are they contagious? Probably not. The vast majority of people exposed to someone with prior c diff don't get sick. But exposure to active c diff could lead to colonization, or even infection if on antibiotics.

Depends: after initial diagnoses, if repeat stool test 5-7 days later is negative then u are nor contagious, but cdiff has spores, and if those spores stay in the colon, especially diverticula, then you can shed spores; u may not have the colitis while the spores are dormant. Hand washing with soap and water is key.

Depends: In most cases, c diff is treated with 2 weeks of antibiotics. This is effective around 85% of the time, but 15% can "relapse" after their antibiotics. This requires more antibiotics. After that, an even higher % will have a 2nd relapse. Treatment is with even more antibiotics. And so on. Some patients have had relapsing diff for years! we can often cure them with a stool transplant.

A female asked:

Is c. diff contagious through airborne?

1 doctor answer1 doctor weighed in
Dr. Stephen Scholand

Definitely not: C. diff is a disease transmitted by the 'fecal-oral' route, which sounds disgusting because it is. Spores from another patient can contaminate the environment that someone might have visited earlier (like a shared bathroom in a 2 bed room in a hospital). Once those are ingested, under certain conditions (antibiotic use mostly), the spores can germinate and cause infection. C. diff can be bad news.
