You're standing in the pharmacy aisle or sitting in a sterile pediatrician's office, and you need to ask about that crusty, honey-colored rash on your kid’s face. You hesitate. Is it im-peh-TEE-go? Or maybe im-PET-ih-go?
You aren't alone. Honestly, medical terminology is a minefield of Latin roots and weird emphasis shifts that make even seasoned nurses second-guess themselves.
So, how do you pronounce impetigo without sounding like you’re making up a spell from a fantasy novel? The short answer is that there is a "dictionary correct" version, but the medical community is surprisingly split on what they actually say in the hallways of a hospital.
The Correct Way to Say It
If you open the Merriam-Webster medical dictionary or consult the Mayo Clinic’s pronunciation guides, the emphasis lands squarely on the third syllable. It’s im-peh-TY-go.
Think of it like this:
- Im (like "impossible")
- peh (like "pet")
- TY (like a necktie)
- go (like "go away")
The "ty" sound is long, rhyming with "eye" or "fly." This is the formal, traditional pronunciation used in academic settings. If you’re giving a presentation at a dermatology conference, this is the one you’d want to use to avoid some side-eye from the old-school professors.
But here’s the kicker. Language is fluid. What’s "correct" in a book isn’t always what’s "common" in the real world.
Why Do People Say It Differently?
A massive chunk of the population—including plenty of doctors—says im-peh-TEE-go. They swap that long "I" sound for a long "E" sound.
Why? It’s likely because of how we process other medical terms. Think of words like vitiligo or intertrigo. In many of those cases, the "igo" suffix leans toward that "EE-go" sound. It feels more natural to the English-speaking ear to keep that rhythmic pattern going.
Then you have the third camp: im-PET-ih-go. This version shifts the stress to the second syllable. While less common, you’ll hear it in various regional dialects across the UK and parts of the Southern United States. It’s not "wrong" in a social sense, but it might get you a clarifying question from a pharmacist.
Does the Pronunciation Actually Matter?
In the grand scheme of things? No.
Medical professionals are trained to understand what you mean, regardless of where you put the emphasis. If you walk into a clinic and mention a "honey-crusted rash," they know exactly what you’re talking about before you even finish saying the word.
However, clear communication helps. Impetigo is a highly contagious bacterial skin infection, usually caused by Staphylococcus aureus or Streptococcus pyogenes. It’s common in children, but adults get it too, especially those in close-contact environments like gyms or barracks.
If you say it clearly, you get to the treatment faster. And treatment is usually just a simple course of topical antibiotics like mupirocin (Bactroban) or, in more stubborn cases, oral antibiotics.
Breaking Down the Greek and Latin Roots
To understand why im-peh-TY-go is the standard, you have to look at the Latin. The word stems from impetere, which means "to attack." It’s the same root we get "impetus" from. In Latin, that "i" in the "igo" suffix is often treated as a long vowel.
When doctors speak to each other, they often use shorthand or slang anyway. You might hear them talk about "bullous" vs. "non-bullous" types.
- Non-bullous impetigo is the most common. It starts as red sores that quickly rupture and leave that signature tan/yellow crust.
- Bullous impetigo features larger blisters that are clear at first and then turn cloudy. These stay on the skin longer without bursting.
Knowing the types is actually more important for your doctor than whether you nailed the long "I" sound in the name.
Misconceptions That Follow the Name
Because people struggle with how to say it, they often misunderstand what it is.
I’ve heard people call it "infantigo" or "empetigo." This confusion sometimes leads parents to think it’s a "dirty" disease or a sign of poor hygiene. That is flat-out false. You can be the cleanest person on earth and still catch it by touching a contaminated gym mat or sharing a towel with someone who has an active lesion.

It’s an opportunistic infection. It looks for a break in the skin—a bug bite, a scratch, or even just raw skin from a cold—and hitches a ride.
How to Talk to Your Doctor About It
When you go in for a consultation, don't sweat the phonetics. Use whichever version feels most comfortable, but focus your energy on the details that matter for a diagnosis.
Tell them when the spots first appeared. Mention if they itch or burn. Most importantly, tell them if you've tried any over-the-counter creams like Neosporin, as these can sometimes mask the appearance of the infection or, in some cases, cause a secondary allergic reaction (contact dermatitis) that complicates the picture.
Real-World Advice for Management
If you or your child has been diagnosed, the pronunciation is the least of your worries. You need to stop the spread.
- Wash everything. Use hot water for towels, bed linens, and clothes.
- Clip the fingernails. Scratching spreads the bacteria to other parts of the body. Short nails mean less "cargo space" for bacteria.
- Cover the sores. A loose bandage can prevent the "weeping" fluid from touching surfaces.
- Finish the meds. This is the big one. Even if the skin looks perfect after three days of cream, keep going for the full prescribed length. If you stop early, you’re just training the bacteria to be resistant.
Final Word on the "Correct" Sound
If you want to sound like a textbook, go with im-peh-TY-go. If you want to sound like the majority of people you’ll meet in a grocery store, im-peh-TEE-go works just fine.
The medical world is full of these linguistic quirks. Think of angina (is it an-JY-na or AN-jin-a?) or capillaries (CAP-ill-aries or ca-PILL-aries?).
The goal of language is to be understood. If you communicate the symptoms and get the prescription, you’ve won the battle.
Actionable Next Steps
- Verify the crust: Look for the "honey-colored" crust. This is the hallmark of impetigo. If the rash looks silvery or like a target, it’s likely something else (like psoriasis or Lyme disease).
- Check for fever: Impetigo is usually localized. If you have the rash and a high fever, the infection might have spread deeper into the skin (cellulitis), which requires much faster medical intervention.
- Sanitize your space: If a child has it, wipe down doorknobs and remote controls with a disinfectant. The bacteria can live on hard surfaces for surprisingly long periods.
- Consult a professional: While the name is hard to say, the diagnosis is usually quick. A telehealth visit is often enough for a doctor to identify it via camera and send a script to your local pharmacy.
