The incubation period is thought to be about 2 to 3 days after exposure. Diagnosis of CDI requires the demonstration of a toxin-positive stool sample in the context of watery diarrhea (or colonoscopy findings), but initiation of treatment usually precedes the diagnostic confirmation.

What is the difference between C. diff and diarrhea?

Overview. Diarrhea is a frequent side effect of antibiotics, occurring 10–20% of the time. It usually gets better when the antibiotics are stopped. Clostridium difficile infection (CDI) is due to a toxin-producing bacteria that causes a more severe form of antibiotic associated diarrhea.

What are the 6 stages of infection?

No matter the germ, there are six points at which the chain can be broken and a germ can be stopped from infecting another person. The six links include: the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host.

What is the main route to spread infection?

Body fluids – A body fluid e.g. blood, urine, pus, saliva from one person enters the body of another e.g. through cuts or other means such as sexual intercourse (e.g. syphilis, HIV etc.). Through saliva (e.g. glandular fever).
