How to Pronounce Infectious Diarrhea

Say it like this: in-FEK-shus dy-ah-REE-ah. The stress falls on the second syllable of the first word (FEK) and the third syllable of the second word (REE). Think of it as saying 'in-FEK-shus' (rhymes with 'infectious') followed by 'dy-ah-REE-ah' (sounds like 'diarrhea').

The word 'infectious' means caused by germs—like bacteria, viruses, or parasites—that spread or multiply in your body. In this term, it tells you that the diarrhea is coming from a harmful organism, not from something else like food intolerance or medication.

It comes from the Latin word 'infectus,' which means 'to taint' or 'to contaminate.' The root 'infect-' is used in many medical words to describe things caused by harmful organisms that enter the body.

Diarrhea is the medical word for loose or watery stools. When a doctor says someone has 'diarrhea,' they mean their bowel movements are more liquid than solid.

Break it like this: in-FEK-shus dy-ah-REE-ah. The first word has four syllables, and the second word has four syllables too, making eight syllables total.

A common mistake is stressing the wrong syllable in 'diarrhea'—people sometimes say dy-ah-RHEE-uh instead of the correct dy-ah-REE-ah. Remember that the stress goes on the third syllable (REE), not the last one.

Several words use the same root: 'infection' (the condition caused by harmful organisms), 'infected' (having harmful organisms), and 'infective' (capable of spreading germs). All of these come from the same Latin root meaning 'to contaminate.'

You might hear it used like this: 'The doctor explained that the patient was being treated for infectious diarrhea.' This sentence tells you that someone has diarrhea caused by germs, rather than by other causes.
