Monkeypox rarely grabs headlines, but its signs of infection can throw you off if you’re not sure what to look for. Early symptoms can mirror common colds or flu, making it easy to miss until the rash appears. Knowing these signs of monkeypox helps you spot the illness sooner, protect loved ones, and get proper care if needed.
This guide breaks down the symptoms step-by-step, covering every stage from the first fever to late-stage complications. You’ll also learn how monkeypox can be confused with other illnesses, when to watch for more serious problems, and when to get medical help. If you want a thorough look at what to expect and how to respond, you’ll find it here.
Early Symptoms of Monkeypox
Catching the signs of monkeypox at the start can help you get ahead of this illness. The first phase usually looks a lot like a typical viral infection—think of how you feel when coming down with the flu. The early symptoms often appear before the signature monkeypox rash, and sometimes they’re easy to miss. But knowing these first signs can make a big difference, especially if there’s a risk of exposure.
Fever and Chills: First Clues Not to Ignore
The first thing most people notice when infected with monkeypox is a sudden fever. Your temperature may climb fast, often reaching 100.4°F (38°C) or higher. Along with this fever, the chills set in. These chills can feel like a wave of cold washing over your body, even if the room is warm. The combination hits hard and can leave you shivering or sweating in turns.
For many, this fever marks the beginning of the illness, signaling your body’s fight against the infection. If you’ve recently been around someone with monkeypox, or there’s an outbreak, don’t brush off this early warning.

Headache, Muscle Aches, and Backache: The Body’s Alarm Bells

Monkeypox doesn’t ease you in quietly. Most people get a pounding headache that feels like pressure or throbbing pain across the forehead or behind the eyes. This isn’t a faint ache—it can stop you in your tracks.
Add to that body aches and a sore, tight back. Muscles across the shoulders and down the back grow stiff and sore, almost like you’ve done a tough workout without remembering when. Joints may feel tender, and every movement can hurt. These aches come alongside the fever, leaving you drained even before other signs appear.
Swollen Lymph Nodes: What Makes Monkeypox Stand Out
Swollen lymph nodes are one of the clearest signs that set monkeypox apart from illnesses like chickenpox or measles. Lymph nodes swell because your immune system is fighting hard. You might notice:
- Tender lumps under your jaw or in your neck
- Swelling in your armpits or groin
- Soreness when you touch these spots
Look for pea-sized or larger bumps—often on both sides of the body. These swollen areas can be painful, and you may spot them before any rash shows up. Their appearance can help doctors tell monkeypox apart from other viral infections, which rarely cause the same swelling.
If you spot swollen lymph nodes and other early symptoms, see a doctor early. The Penn Medicine guide to monkeypox symptoms gives a helpful breakdown of how these signs show up.
Fatigue and Exhaustion: A Sudden Loss of Energy
One of the most common, yet easy-to-miss signs of monkeypox is severe fatigue. This isn’t just regular tiredness. You may feel a deep, bone-weary exhaustion. Staying awake feels like a chore. It can start before skin changes, catching you off guard.
People often say they can’t get out of bed—they’re just too tired. Even everyday tasks seem impossible. This fatigue goes beyond sleepiness; it lingers even if you rest, and it’s usually one of the main reasons people seek help.

Spotting these signs early matters most, especially when cases are spreading. Pay attention if you or someone close to you feels any of the above, especially if the signature rash appears later.
The Monkeypox Rash: Appearance and Progression
Once the early flu-like signs of monkeypox appear, most people brace themselves for the rash. This rash is one of the signature signs of the illness. It acts as a turning point where you know this isn’t just any fever. Here’s what the monkeypox rash looks like, where it shows up, how it changes, and what it feels like along the way.
Mouth, Face, Hands, and Genital Areas: Where the Rash Appears

Monkeypox rash doesn’t pick just one place on the body. It can break out anywhere, but there are common spots where you are most likely to see new bumps first:
- Face and mouth: Many notice the first spots on the face or even inside the mouth.
- Hands and palms: It’s very common to see lesions appear on your hands and the soles of your feet.
- Genital and anal areas: Some notice rashes near the groin, anus, or thighs. These can be easy to mix up with other skin conditions.
- Arms, legs, chest, and back: The rash can spread almost anywhere as it worsens.
The rash doesn’t always follow the same pattern for everyone. Some get just a few spots. Others are covered from head to toe. According to experts, monkeypox lesions tend to group in these areas, which helps set this apart from chickenpox or other skin problems. To see clinical photos and expert advice, check out the Dermatologist explains what the mpox (monkeypox) rash looks like.
Stages of the Rash: Macules, Papules, Vesicles, Pustules, Scabs
The monkeypox rash goes through a set of changes, with each stage lasting a few days. Recognizing these phases helps you spot the infection early and track its progress.
The 5 Main Stages:
- Macules (Days 0–2): Flat, round, and discolored spots appear. They aren’t raised and may be easy to miss.
- Papules (Days 1–4): These spots become raised, forming firm, painful bumps. At this point, the rash starts looking more serious.
- Vesicles (Days 2–6): Fluid-filled blisters form. These look like clear bubbles or little water blisters.
- Pustules (Days 4–7): The blisters fill with thick, yellow pus. These spots become hard, deep, and can look like boils.
- Scabs (Days 7–14): Bumps dry out, crust over, and finally scab. Once the scabs fall off, new skin forms underneath.
Not everyone goes through each stage at the same speed, but the whole process often lasts between 2–4 weeks. Your rash may be more severe if you have a weak immune system or other health issues. The CDC’s clinical features of mpox has a clear timeline and photos showing each step.

Pain and Itching: Sensations Linked to the Rash
There’s no sugar-coating it: the monkeypox rash can be painful, tender, and itchy. Each stage feels different.
- Early spots (macules and papules): Mild discomfort or slight itch at first.
- Blisters and pustules: These swell, stretch the skin, and hurt. The pressure in these bumps can be sharp or throbbing, especially if sores are on the hands, feet, or near tender tissue.
- Scabbing: As lesions crust over, itching gets worse. Many people find it hard to resist scratching, which can lead to scars.
On top of pain and itch, some people notice the skin is extra sensitive or burning. Mouth ulcers and lesions around genitals or eyes are especially tough to cope with. The rash can disrupt sleep, make eating hard, and trigger anxiety. Both physical and mental fatigue often increase until the scabs heal and drop off. Visit the CDC guide on signs and symptoms of mpox for more details about these sensations.
If you notice these signs of rash—especially in the usual spots and following fever or swollen lymph nodes—it’s wise to talk to a healthcare provider. Your comfort and skin healing depend on early action and support.
Complications and Severe Cases
Monkeypox is usually mild, but it can take a sharp turn. Complications bring new symptoms and risk. Some people get better without much trouble, while others may face serious outcomes. Knowing what to watch for can make a real difference. Here’s what can happen in severe cases and which signs mean you need help right away.
Infections, Vision Problems, and Other Dangers
When monkeypox moves past the rash and fever, your body faces more stress. Some people get secondary infections or struggle with serious issues. Here are examples of complications to watch for:
- Secondary Skin Infections: Open sores let bacteria in. Infected skin turns red, hot, swollen, or pus-filled. Without antibiotics, this can spread. Skin infections are also common after scratching, much like what happens with bedbug infestation warning signs where broken skin gets infected if not cared for.
- Eye Problems: If the rash spreads to your eyes, this is a big danger. Redness, tearing, pain, or vision changes can mean the virus is hurting the eye itself. Without treatment, it may lead to lost vision or blindness.
- Pneumonia: Breathing trouble and cough can signal the infection has moved to your lungs. This can cause shortness of breath, chest pain, and low oxygen.
- Encephalitis: This means the brain is swollen or inflamed. You might notice confusion, trouble speaking, seizures, or unresponsiveness. It’s rare, but serious.
- Sepsis: If bacteria from skin lesions enter the blood, a life-threatening infection called sepsis can develop. Symptoms include fever, confusion, and rapid breathing.
- Dehydration and Malnutrition: Painful mouth sores and severe rash make eating and drinking difficult, sometimes causing dehydration.
Some people—especially kids, pregnant women, or those with weak immune systems—have a higher risk of severe disease. If the rash covers much of the body, or you see red streaks, pus, or swelling at the site, act fast.

When to Seek Help
There are clear signs of monkeypox that mean you should see a doctor right away. These warning signs show things could get worse fast:
- Trouble breathing or shortness of breath
- Chest pain or tightness
- Severe headache or neck stiffness
- Confusion or acting very strange
- Seizures or fainting
- Vision changes—blurry sight, pain, redness, or sensitivity to light
- Drainage, swelling, or streaks from skin lesions
- High fever that won’t come down, or shaking chills
- Trouble eating or drinking, causing signs of dehydration (very dark urine, dry mouth, dizziness)
- Severe abdominal pain or vomiting
Quick action lowers the risk of lasting harm. If you or someone you know has these signs, get medical care without delay. Doctors can provide treatments, help prevent lasting damage, and guide next steps.

How Monkeypox Symptoms Progress and What to Expect
Monkeypox doesn’t strike all at once. It moves in clear steps, with one stage flowing into the next. This pattern is one of the most helpful signs of monkeypox. Recognizing these changes gives you a way to keep watch, and spot trouble early. Each person’s signs of illness may look slightly different, but most cases follow a set path whether mild or severe.
Progression Timeline: A Step-by-Step View
The illness starts within 1 to 3 weeks after you come into contact with the virus. The first stage hits like the flu, then comes the rash, which slowly changes in shape and feel.
Here’s how the symptoms typically unfold:
-
Incubation Period
After exposure, nothing seems wrong at first. This stage lasts from 5 to 21 days. You won’t see signs of illness yet, but the virus is getting ready. -
Early Illness (Day 1-5 of Symptoms)
Now, you begin to feel sick. You get a fever, muscle aches, headaches, chills, and swollen lymph nodes. Fatigue or deep tiredness can be strong. These early signs make monkeypox easy to confuse with other common illnesses. -
Rash Onset (1-4 days after fever starts)
The rash appears soon after fever and swollen lymph nodes. It often starts on the face, then moves to palms, soles, or genitals, but it can show up almost anywhere. The rash starts as spots (macules), then raises up (papules), turns into blisters (vesicles), and fills with fluid or pus (pustules) before crusting and dropping off as scabs.

Lesions Heal and Recovery (2-4 weeks)
Scabs form and fall off, sometimes leaving pale marks or scars. You’re no longer contagious once all scabs have dropped away and healthy skin forms underneath.
What Changes Day by Day
You’ll notice that signs of monkeypox change each day. At first, you’re fighting off aches, pain, and fever. As the rash breaks out, the pain and itch can feel overwhelming. During recovery, the rash fades, and your other symptoms ease up.
- Fever and aches usually last 1-4 days.
- The rash stage lasts 2-3 weeks on average.
- You might feel tired or weak for some time after other signs fade.
How Symptoms Compare to Other Illnesses
Monkeypox often gets confused with chickenpox, shingles, or hand, foot, and mouth disease at first. What sets it apart? Pay attention to these clues:
- Swollen lymph nodes are much more likely with monkeypox than chickenpox.
- The rash changes in clear stages in the same order for almost everyone.
- Flu-like signs of illness come before the rash, not at the same time.
These hints help doctors sort out monkeypox from other problems, and why it’s so important to notice the order and style of each sign. For more, see the CDC’s summary of monkeypox signs and symptoms.
When Healing Takes Longer
Most people recover within a month, but things don’t always go smoothly. If you scratch the rash or lesions get infected, healing can stall. Some folks heal slower if their immune system is already weak. As a rule, keep skin clean, avoid picking at scabs, and rest while the body works to heal the skin and stop the virus.
You can read more about the full timeline and tips for recovery at the Mayo Clinic’s monkeypox FAQ and check out what to watch for during each stage.
Monkeypox symptoms follow a pattern that’s clear when you know what to expect. Learning each step gives you the tools to track changes and spot trouble before it starts.
Conclusion
Early signs of monkeypox start quietly, but they set the stage for every symptom that follows. Fever, muscle aches, swollen lymph nodes, and the signature rash all tell a story your body can’t ignore. Being quick to spot these changes helps you protect yourself and those around you.
Stay alert to any sudden fever, tiredness, or unusual rash. Act fast if the signs of trouble grow worse or don’t fit the usual course. Clean hands, careful contact, and safe habits can lower your risk and help stop the spread.
