Acute flaccid myelitis (AFM) is a condition that affects the nerves in children. It leads to sudden muscle weakness. Since 2012, there have been global outbreaks of AFM linked to non-polio enterovirus infections.
Children with AFM may develop severe muscle weakness. This can make breathing hard and cause other problems. Doctors diagnose AFM by looking at a child’s symptoms, certain scans, and spinal fluid tests.
Key Takeaways:
- AFM is a neurological disorder primarily affecting children, characterized by sudden muscle weakness.
- Outbreaks of AFM have been reported globally since 2012.
- AFM is believed to be caused by non-polio enterovirus infections.
- Diagnosing AFM involves identifying specific clinical, neuroimaging, and cerebrospinal fluid characteristics.
- AFM can lead to respiratory failure and other complications.
Understanding Acute Flaccid Myelitis
Acute flaccid myelitis (AFM) is a type of paralysis. It’s known for causing sudden muscle weakness and limb paralysis in kids. This disorder is often linked to enterovirus infections.
AFM leads to different levels of muscle weakness. It can affect kids for a long time. It’s similar to other nerve problems like Guillain-Barré syndrome. This means it can hinder the way the body works.
AFM may begin with symptoms like a cold, with fever and cough. But it can quickly progress to severe muscle weakness and limb paralysis. Some people might find their face or throat muscles are weak, leading to drooping or trouble swallowing.
AFM is different from other illnesses, but doctors can tell them apart. They look at the person’s symptoms and tests. They might use MRI scans and fluids from around the brain and spinal cord. This helps them give a definite AFM diagnosis.

Epidemiology of AFM
AFM is a serious health issue around the world. It has caused outbreaks in many places. Although it’s hard to know exactly how common AFM is, systems are in place to watch for it and its spread.
Research Insights
Scientists and doctors are working hard to understand and treat AFM better. They want to know why it happens and what can be done. One line of research is looking into stem cell therapy as a possible treatment.
Causes and Risk Factors of AFM
The exact cause of Acute Flaccid Myelitis (AFM) isn’t fully understood. But it’s mostly linked to certain enterovirus infections. For example, enterovirus D68 seems to play a big part. Enterovirus A71 is also connected to AFM cases. These viruses commonly cause diseases that affect the lungs. Sometimes, they can lead to AFM.
Several things can increase the chance of getting AFM. It’s mainly kids who get it, so age is a big factor. Certain areas see more cases during the enterovirus season. If someone has had viral infections before, especially those affecting the breathing, their risk of AFM goes up.
Epidemiology of AFM
The number of AFM cases varies over time and by place. Since 2012, there have been outbreaks around the world. The U.S. has seen more cases recently. Other countries also report AFM cases, but they’re less common.
More people now know about AFM and look for it. This has helped find and record more cases. Still, the actual number of AFM cases might be higher. Some cases could be missed or mistaken for something else. Doing more research and tracking cases better is key to understanding AFM’s global reach.
Non-Polio Enterovirus Associated with Acute Flaccid Myelitis (AFM)

Many people get infected with enteroviruses worldwide. Yet, only a few develop AFM because of them. Why some get AFM and others don’t is still a mystery. Scientists are working on understanding these differences.
Symptoms and Clinical Presentation of AFM
Acute flaccid myelitis (AFM) shows with muscle weakness, limb paralysis, and trouble breathing. This condition mostly affects children. It can change their lives by limiting their movement and coordination.
Severe cases of AFM can lead to being unable to breathe on their own. This is very dangerous and needs quick medical help. Besides paralysis, other signs include a weak neck, a drooping face, and finding it hard to swallow.
Diagnosing AFM is tricky because its symptoms are like those in other illnesses. But it’s important to carefully check all symptoms. This helps doctors understand if it’s AFM or something else.
An overview of symptoms associated with AFM:
- Muscle weakness
- Limb paralysis
- Respiratory difficulties
- Neck weakness
- Facial drooping
- Difficulty swallowing
For a clearer picture, check the table below for AFM symptoms:
| Symptom | Description |
|---|---|
| Muscle weakness | Loss of strength and control in the affected muscles, leading to impaired movement and function. |
| Limb paralysis | Complete or partial loss of motor function in one or more limbs. |
| Respiratory difficulties | Challenges in breathing, ranging from mild shortness of breath to respiratory failure. |
| Neck weakness | Weakening of the muscles in the neck, affecting stability and range of motion. |
| Facial drooping | Sagging or weakness in the facial muscles, resulting in asymmetry and difficulty in facial expressions. |
| Difficulty swallowing | Impaired ability to swallow food, drinks, or saliva, causing discomfort and potential complications. |
Knowing these symptoms is key for doctors. They help in telling AFM apart from other illnesses. This leads to better care and improved chances for the patient.
Diagnosis and Differential Diagnosis of AFM
Diagnosing Acute flaccid myelitis (AFM) is tough because there’s no single test for it. Doctors look at a lot of things like symptoms, images of the brain and spine, and testing your spinal fluid. All of this helps tell AFM apart from diseases that seem similar.
Diagnostics for AFM
When looking at AFM, it all starts with checking your story and your body. A doctor talks with you and looks closely at how your body moves or doesn’t move. They’re searching for things like weak muscles or not being able to move your limbs.
Next, comes the use of brain and spine images to find AFM clues. Magnetic resonance imaging (MRI) is the go-to for showing issues in the spine’s nerve tissue, like abnormal spots. These spots tell us about swelling and injury in that area.
Getting some of your spinal fluid for testing is also key. This step, called a lumbar puncture or spinal tap, looks for certain signs in your spinal fluid. It can find things like more white blood cells than normal or too much protein, which might mean something is up.
Differential Diagnosis
To make sure it’s AFM and not something else, doctors also look at diseases that act like it. They keep a close eye on other nervous system issues that share similar symptoms. These can include Guillain-Barré syndrome, transverse myelitis, or even certain infections.
So, doctors don’t just look at your symptoms. They also consider your medical history and test results. This careful process makes sure you get the right treatment and the best care possible.
The image shows tools and steps for diagnosing AFM. These methods are crucial for picking out AFM and making sure the treatment fits perfectly.
Management and Treatment of AFM
There is not a specific treatment for AFM. But, doctors focus on giving care and help. The goal is to make life better for those with AFM.
Care is very important to deal with breathing problems. Some people with AFM need a machine to help them breathe. It’s also key to check their breathing often.
Another big part of AFM care is therapy. It’s meant to make bodies work better and get muscles stronger. Therapists use exercises and other methods to help in moving and talking better.
Sometimes, surgery might be needed to fix problems AFM leaves behind. It could help improve how someone can move and do things. But, not everyone will need surgery.
Experts keep looking for better ways to treat AFM. They’re studying new drugs and therapies. Stem cell therapy, for example, might help repair nerve damage.
