what do measles look like

A measles rash typically appears as red, reddish-brown, or purple blotchy patches that are usually flat or slightly raised, and it does not normally itch.¹²³⁴⁵

How the Rash Spreads and Looks

• Starting Point: It usually starts around the hairline, face, and behind the ears.¹²³
• Downward Spread: Over a few days, the spots spread downward to the neck, chest, back, arms, legs, and feet.¹²
• Blotchy Appearance: Individual spots often merge or join together into larger, flat or bumpy red patches.¹²³
• Skin Tone Differences:
  • On lighter skin, the spots look vivid red, pink, or red-brown.
  • On brown and black skin, the rash can look purple or darker than the surrounding skin, and individual bumps may be harder to spot clearly.¹²³

Other Key Signs (Before and With the Rash)

• Koplik’s Spots: Small, greyish-white or bluish-white spots often appear inside the mouth (on the inner cheeks and back of the lips) a day or two before the skin rash starts.¹²³
• Early Flu-like Symptoms: Measles begins about 10 to 14 days after exposure with a high fever, a dry cough, a runny nose (coryza), sneezing, and very red, sore, watery eyes (conjunctivitis).¹²³⁴

You can learn more about symptoms and care from the NHS Measles Guide or review photo examples via the CDC Measles Photos.¹²If you'd like to share more context, let me know:

• Who has the symptoms (an adult or a child, and their age)?
• When did the first symptoms or rash start?

I can help you understand what steps to take next or when to contact a healthcare provider.

The measles rash has a distinct look and progression, typically showing up a few days after you first start feeling unwell with cold-like symptoms.¹

Key Visual Characteristics of the Rash

• Appearance: It consists of flat red or reddish-brown spots that are sometimes slightly raised. As the rash develops, these individual spots often join together into larger, blotchy patches.¹
• Itchiness: Unlike many other childhood rashes (like chickenpox or eczema), the measles rash is not usually itchy.¹
• Skin Tone Variations: The rash looks distinctly red or reddish-brown on white skin, but it can be harder to see or appear darker/purple-brown on brown and black skin.¹

Where It Starts and How It Spreads

1. Face and Ears First: The rash almost always makes its first appearance on the face, hairline, and behind the ears.¹²
2. Downward Spread: Over the next couple of days, it spreads downward across the neck, torso, arms, legs, and finally down to the hands and feet.¹
3. Fading: After a few days on the body, the rash begins to fade in the exact same order it appeared (from the head downwards), sometimes leaving a faint brownish discoloration or light flaking of the skin.¹

What to Look for Inside the Mouth (Koplik Spots)

Before the skin rash even appears, a hallmark sign of measles shows up inside the mouth:¹

• Koplik spots: Small white spots (often compared to tiny grains of salt with a red background) that develop inside the cheeks and on the back of the lips a couple of days into the illness.¹²

Early Warning Signs (Before the Rash)

The rash doesn’t show up right away. For the first 2 to 4 days, measles mimics a severe cold or flu:

• High temperature (fever)
• Runny or blocked nose, sneezing, and a persistent cough
• Red, sore, watery, or inflamed eyes (conjunctivitis)
• General exhaustion and loss of appetite ¹

(For official visual references and clinical examples, you can check the CDC Photos of Measles or the NHS Measles Guide.)

Are you or someone you know currently experiencing these symptoms, or would you like guidance on when to contact a GP or 111?

Measles usually causes a distinctive red, blotchy rash that starts on the face and spreads down the body. It often looks like small red or brownish-red spots that can join together to form larger patches.

What does a measles rash look like?

Typical features:

• Red or reddish-brown blotches.
• Flat spots, sometimes slightly raised.
• Often start around the hairline, behind the ears and on the face.
• Spread down the neck, chest, arms, legs and feet.
• Can merge into larger red patches.
• May be itchy, but isn't always.

Other early symptoms

Measles usually begins with symptoms similar to a bad cold, before the rash appears:

• High fever.
• Runny nose.
• Cough.
• Red, watery eyes.
• Feeling very tired or unwell.
• Tiny white spots inside the mouth (called Koplik spots).

When does the rash appear?

1. Days 1–4: Fever, cough, runny nose and red eyes.
2. Around days 3–5: Red rash appears, usually starting on the face.
3. Following days: Rash spreads down the body.
4. Around a week: Rash gradually fades.

(Important)

Measles is extremely contagious. If you think you or your child might have it, stay at home and phone your GP or NHS 111 before attending anywhere. Don't go into a GP surgery or hospital waiting room without calling first.

If you have a suspected measles infection alongside difficulty breathing, a seizure, severe drowsiness or confusion, seek emergency medical help (999 in the UK).

Can I ask: Are you asking because you've noticed a rash on yourself or someone else? If so, tell me where it is and what it looks like, or upload a photo, and I can help you understand whether it resembles measles.
