Yes, while rare, croup (laryngotracheitis) can develop into pneumonia (lower respiratory infection) or bacterial tracheitis (windpipe infection) as a secondary complication, especially if symptoms worsen or don't improve, indicating a more severe bacterial involvement or deeper lung infection. Croup itself is usually a self-limiting viral illness affecting the upper airways (larynx, trachea), but severe cases risk complications like pneumonia or respiratory failure, requiring prompt medical attention.
Most cases of croup are mild. In a small number of children, the airway swells enough to cause problems with breathing. Rarely, a bacterial infection of the windpipe can occur in addition to the viral infection. This can result in trouble breathing and requires emergency medical care.
Early signs of pneumonia often mimic cold or flu but worsen, including fever, chills, cough (with or without mucus), fatigue, and shortness of breath, sometimes with chest pain, rapid breathing, headache, and loss of appetite, notes Healthdirect, Better Health Channel, American Lung Association, and Mayo Clinic. In older adults, confusion or disorientation can be a key sign, while infants might show restlessness or feeding difficulties, say Healthdirect, Mayo Clinic, and WebMD.
As the upper airways — the voice box (larynx) and windpipe (trachea) — become irritated and swollen, a child may become hoarse and have the barking cough. If the airways continue to swell, breathing gets harder. Kids often make a high-pitched or squeaking noise while breathing in — this is called stridor.
Stage 1: Congestion. Stage 2: Red hepatization. Stage 3: Grey hepatization. Stage 4: Resolution.
Although uncommon, some children with moderate to severe croup are at risk for respiratory failure if not enough oxygen is able to get to their organs. Bacterial infections, such as pneumonia or bacterial tracheitis, may arise from croup and can be life-threatening.
Walking pneumonia symptoms to look for:
Children with mild croup usually improve in three to seven days. Croup can present with more severe symptoms and breathing issues that don't resolve with simple home measures. If you have concerns about your child's breathing, you should bring them for medical evaluation right away.
Since croup is caused by a virus, antibiotics are not necessary. In more severe cases, your doctor might determine that your child needs an oral steroid. Some children may develop croup during or just after a cold.
Conditions that can be mistaken for croup include:
As pneumonia can be life-threatening, it's important to seek medical attention for serious symptoms that could be signs of pneumonia, such as: Congestion or chest pain. Difficulty breathing. A fever of 102 degrees Fahrenheit (38.88 degrees Celsius) or higher.
A pneumonia cough may sound deeper or louder than a cough associated with other viral and bacterial conditions. 1 It also tends to be wet and productive (produces mucus). Features of a pneumonia cough, such as the type of mucus you cough up, will depend on the type and stage of the pneumonia.
Signs and symptoms of pneumonia may include: Chest pain when you breathe or cough. Confusion or changes in mental awareness (in adults age 65 and older) Cough, which may produce phlegm.
If the child develops more severe symptoms or experiences ongoing symptoms, refer them to a health care provider to be checked for secondary complications (such as bronchitis, sinus infections, middle ear infections, and laryngitis).
Kids with bacterial pneumonia usually get sick quickly and have a high fever, cough, rapid breathing and maybe even chest pain with breathing. Viral pneumonia symptoms tend to appear more slowly and may be less severe, though you can see fever and cough from viruses too. Wheezing is more common in viral pneumonia.
They may also have a hoarse voice and find it difficult to breathe because their airway is blocked. Some children have cold-like symptoms for a few days before developing croup symptoms. Croup symptoms usually only last for a few days and are often worse at night. But they can occasionally last up to 2 weeks.
Epinephrine. Nebulized epinephrine is recommended for moderate to severe croup. Reports of administering epinephrine in children with severe croup have demonstrated a lower number of cases requiring intubation or tracheotomy (19).
The most common cause of croup is a viral infection. Croup viruses include parainfluenza, influenza, respiratory syncytial virus (RSV), measles and adenovirus. Viral croup causes your child's upper airways to swell, making it difficult for them to breathe.
Urgent advice: Ask for an urgent GP appointment or call NHS 111 if: you think your child may have croup – the doctor may give your child medicine to shorten the illness.
Croup symptoms are often worse on the second or third night of the illness. The barking cough can last for up to a month.
Sleep. Children with croup should be allowed to rest as much as possible because this helps their body to fight the viral infection that is responsible for causing croup.
If the epiglottis becomes infected, the entire windpipe can swell shut. This is a life-threatening condition. If an airway blockage is not treated promptly, the child can have severe trouble breathing or breathing may stop completely.
So you've been coughing for a while, and instead of getting better, it seems like your cough is getting worse. Maybe you've even started coughing up phlegm or have pain in your chest when you cough. Those are signs your cough might actually be pneumonia.
The most common symptoms of bronchitis are:
The immune system is usually able to fight walking pneumonia on its own, without the need for medical intervention. Self-care can help speed your recovery, and certain over-the-counter medications can relieve symptoms. In more severe or persistent cases, antibiotics may be prescribed.
