Croup is a common respiratory infection in children that causes a barking cough, hoarseness, and difficulty breathing. It is caused by a virus, bacteria, or other irritants that inflame the larynx (voice box), trachea (windpipe), and bronchi (airways).
Croup is most common in children between the ages of 6 months and 3 years, but it can occur at any age. It is usually a mild illness that lasts for a few days, but it can be more severe in some cases.
In this article, we will discuss the causes, symptoms, diagnosis, treatment, and prevention of croup.
What is Croup
Croup is a common childhood respiratory infection causing barking cough, hoarseness, and breathing difficulty.
- Common in children 6 months to 3 years

Croup is a common illness that can be frightening for parents, but it is usually mild and resolves quickly with treatment.
Common in children 6 months to 3 years
Croup is most common in children between the ages of 6 months and 3 years. This is because their airways are smaller and more easily irritated than those of older children and adults. Additionally, their immune systems are still developing, making them more susceptible to infection.
- Narrow airways: Children's airways are smaller and narrower than those of adults. This makes them more prone to swelling and obstruction, which can lead to croup.
- Developing immune systems: Children's immune systems are still developing, making them more susceptible to infection. This means they are more likely to catch the viruses and bacteria that can cause croup.
- Exposure to triggers: Children are more likely to be exposed to triggers that can cause croup, such as cold air, smoke, and dust. They are also more likely to put things in their mouths, which can introduce germs and irritants into their airways.
- Frequent respiratory infections: Children have more frequent respiratory infections than adults. This is because their immune systems are still developing and they are more likely to be exposed to germs.
While croup can occur in children of any age, it is most commonly seen in toddlers and preschoolers. This is because their airways are still small and their immune systems are still developing.
Caused by virus, bacteria, or irritants
Croup can be caused by a variety of factors, including viruses, bacteria, and irritants.
- Viruses: Viruses are the most common cause of croup. The parainfluenza virus is the most common culprit, but other viruses, such as respiratory syncytial virus (RSV) and influenza, can also cause croup.
- Bacteria: Bacteria can also cause croup, but this is less common. The most common bacterial cause of croup is Streptococcus pneumoniae (pneumococcus).
- Irritants: In some cases, croup can be caused by irritants, such as smoke, dust, and cold air. These irritants can inflame the larynx, trachea, and bronchi, leading to the symptoms of croup.
- Allergies: Allergies can also trigger croup in some children. This is because allergies can cause inflammation and swelling in the airways, which can lead to croup symptoms.
In most cases, croup is caused by a virus. However, it is important to see a doctor to get the correct diagnosis and treatment.
Inflames larynx, trachea, and bronchi
Croup is a respiratory infection that causes inflammation of the larynx (voice box), trachea (windpipe), and bronchi (airways). This inflammation can lead to swelling and narrowing of the airways, which can make it difficult to breathe.
The larynx is a small, cartilaginous structure that sits at the top of the trachea. It contains the vocal cords, which vibrate to produce sound. The trachea is a long, thin tube that carries air from the larynx to the lungs. The bronchi are the two large branches of the trachea that enter the lungs.
When croup causes inflammation of the larynx, trachea, and bronchi, it can lead to a variety of symptoms, including:
- Barking cough: This is the most common symptom of croup. It is caused by the inflammation and swelling of the larynx.
- Hoarseness: This is also caused by the inflammation and swelling of the larynx.
- Difficulty breathing: This can be caused by the swelling and narrowing of the airways.
- Stridor: This is a high-pitched, whistling sound that is caused by the air passing through the narrowed airways.
In severe cases of croup, the swelling and narrowing of the airways can be so severe that it can lead to respiratory distress. This is a medical emergency and requires immediate treatment.
Croup is usually a mild illness that resolves quickly with treatment. However, it is important to see a doctor right away if your child has any of the symptoms of croup, especially if they are having difficulty breathing.
Symptoms include barking cough, hoarseness, and difficulty breathing
The most common symptoms of croup are barking cough, hoarseness, and difficulty breathing.
Barking cough: This is the most characteristic symptom of croup. It is a harsh, high-pitched cough that sounds like a dog barking. The cough is caused by the inflammation and swelling of the larynx.
Hoarseness: This is also a common symptom of croup. It is caused by the inflammation and swelling of the larynx. Hoarseness can make it difficult to speak or cry.
Difficulty breathing: This can be a sign of severe croup. It is caused by the swelling and narrowing of the airways. Difficulty breathing can be mild or severe. In severe cases, it can lead to respiratory distress.
Other symptoms of croup can include:
- Stridor: This is a high-pitched, whistling sound that is caused by the air passing through the narrowed airways.
- Fever
- Runny nose
- Sore throat
- Swollen lymph nodes in the neck
Croup is usually a mild illness that resolves quickly with treatment. However, it is important to see a doctor right away if your child has any of the symptoms of croup, especially if they are having difficulty breathing.
Croup can be frightening for parents, but it is important to stay calm and seek medical attention if your child is showing any of the symptoms of croup.
Usually mild and lasts a few days
Croup is usually a mild illness that lasts for a few days. Most children recover completely within a week.
The symptoms of croup typically start out mild and gradually worsen over a few days. The barking cough is usually the first symptom to appear. It is often worse at night. The hoarseness and difficulty breathing usually develop within a few hours or days.
Croup is usually caused by a virus, and there is no specific cure. Treatment is focused on relieving the symptoms and making the child comfortable. This may include rest, fluids, and over-the-counter medications to reduce fever and pain.
In most cases, croup is a self-limited illness, meaning that it will resolve on its own without treatment. However, it is important to see a doctor right away if your child has any of the symptoms of croup, especially if they are having difficulty breathing.
Croup can be frightening for parents, but it is important to remember that it is usually a mild illness that resolves quickly with treatment.
Can be more severe in some cases
Croup is usually a mild illness, but it can be more severe in some cases. This is especially true for children who are very young, have other medical conditions, or who have a severe infection.
- Very young children: Children under the age of 6 months are at highest risk for severe croup. This is because their airways are very small and easily obstructed.
- Other medical conditions: Children with other medical conditions, such as heart disease, lung disease, or a weakened immune system, are also at higher risk for severe croup.
- Severe infection: Children with a severe infection are also at higher risk for severe croup. This is because the infection can cause more inflammation and swelling in the airways.
- Epiglottitis: Epiglottitis is a rare but serious infection of the epiglottis, a small flap of tissue that covers the larynx. Epiglottitis can cause sudden and severe swelling of the epiglottis, which can block the airway.
In severe cases of croup, the swelling and narrowing of the airways can be so severe that it can lead to respiratory distress. This is a medical emergency and requires immediate treatment.
Diagnosed with physical exam and medical history
Croup is diagnosed based on a physical exam and medical history. The doctor will ask about your child's symptoms, including when they started and how they have progressed. They will also listen to your child's breathing and look for signs of swelling and inflammation in the larynx, trachea, and bronchi.
In some cases, the doctor may order a chest X-ray to confirm the diagnosis of croup. This is especially true if your child has severe symptoms or if the doctor is concerned about other medical conditions, such as epiglottitis or pneumonia.
Croup can usually be diagnosed based on the physical exam and medical history. However, in some cases, additional tests may be needed to rule out other conditions.
It is important to see a doctor right away if your child has any of the symptoms of croup, especially if they are having difficulty breathing. Early diagnosis and treatment can help to prevent complications.
Treatment includes rest, fluids, and medication
The treatment for croup depends on the severity of the symptoms. In most cases, treatment is focused on relieving the symptoms and making the child comfortable.
- Rest: Getting plenty of rest can help the body fight off the infection.
- Fluids: Drinking plenty of fluids helps to keep the throat moist and prevent dehydration.
- Over-the-counter medications: Over-the-counter pain relievers and fever reducers, such as acetaminophen or ibuprofen, can help to relieve fever and pain.
- Cool mist: A cool mist humidifier or vaporizer can help to soothe the irritated airways.
In some cases, your doctor may prescribe medications to help reduce the inflammation and swelling in the airways. These medications may include:
- Oral steroids: Oral steroids, such as prednisone, can help to reduce inflammation in the airways.
- Inhaled epinephrine: Inhaled epinephrine is a bronchodilator that can help to open up the airways.
Prevention includes avoiding exposure to triggers
There is no cure for croup, but there are things you can do to help prevent your child from getting it.
Avoid exposure to triggers: One of the best ways to prevent croup is to avoid exposure to the triggers that can cause it. This includes:
- Colds and other respiratory infections: Teach your child to wash their hands frequently and to avoid contact with people who are sick.
- Smoke: Avoid smoking around your child and keep them away from secondhand smoke.
- Dust and pollen: Keep your child's bedroom clean and dust-free. Use a HEPA filter in your child's bedroom to remove pollen and other allergens from the air.
- Cold air: Keep your child warm in cold weather. Cover their mouth and nose with a scarf or mask when they go outside.
It is also important to keep your child's vaccinations up to date. This will help to protect them from the viruses and bacteria that can cause croup.
Most children recover completely
Most children recover completely from croup within a few days. However, some children may have lingering symptoms, such as a cough or hoarseness, for a few weeks.
In rare cases, croup can lead to complications, such as pneumonia or epiglottitis. These complications are more common in children who have other medical conditions, such as heart disease or lung disease.
If your child has croup, it is important to follow the doctor's instructions for treatment. This will help to reduce the risk of complications and ensure that your child recovers completely.
Croup can be a frightening illness, but it is important to remember that most children recover completely. With early diagnosis and treatment, the risk of complications is low.
