Bronchitis vs. Pneumonia: How to Tell the Difference and When to Come In

A lingering cough after a cold is worth getting checked.

Quick answer: Bronchitis vs. pneumonia comes down to where the infection sits and how sick it makes you. Bronchitis is inflammation of the airways that carry air into your lungs, and it usually clears on its own. Pneumonia is an infection deep in the air sacs of the lung, it can turn serious fast, and it often needs a chest X-ray and treatment. If you are coughing here on the Mississippi Gulf Coast and cannot tell which one you have, our walk-in team in Vancleave can check your lungs the same day.

A lingering cough after a cold sends a lot of people through our doors in Vancleave, Gautier, and Ocean Springs. Most of the time it is bronchitis and it will fade with rest. Sometimes it is pneumonia, which is a different animal. Here is how to tell them apart, and the signs that mean it is time to be seen.

What is the difference between bronchitis and pneumonia?

The difference is location and depth. Bronchitis is inflammation of the bronchial tubes, the airways that carry air to your lungs, so it is often called a chest cold. Pneumonia is an infection of the tiny air sacs inside the lungs, called alveoli, which can fill with fluid or pus. That is why pneumonia tends to cause more shortness of breath, higher fevers, and a sicker overall feeling than bronchitis.

Acute bronchitis is almost always viral. At least 90% of acute bronchitis cases are viral, the American Academy of Family Physicians (AAFP) reports, so antibiotics usually do nothing to help it. Pneumonia is different. In adults it is most often bacterial, and bacterial pneumonia generally does need antibiotics, so getting the right diagnosis actually changes the treatment.

How do the symptoms compare?

Both start with a cough, but pneumonia usually brings a cluster of whole-body symptoms that a simple chest cold does not. Bronchitis leans toward a nagging cough and chest soreness. Pneumonia adds fever with sweating and chills, shortness of breath, rapid breathing, and sharp chest pain when you breathe or cough, according to the American Lung Association.

How does a chest X-ray tell bronchitis vs. pneumonia apart?

A chest X-ray is the single clearest way to separate the two, because pneumonia shows up on the film and simple bronchitis does not. As RadiologyInfo.org, produced by the Radiological Society of North America and the American College of Radiology, explains, “An x-ray exam will allow your doctor to see your lungs, heart and blood vessels to help determine if you have pneumonia.” Infected areas of lung appear as white patches, called infiltrates, against the normally dark, air-filled lung.

In patients with symptoms of acute bronchitis, imaging is used mainly to rule out pneumonia, per AAFP guidance. That is exactly why an in-house X-ray matters. At our Vancleave clinic we keep X-ray and lab in-house, with results back during the same visit, so instead of guessing about a stubborn cough you can get an answer in one trip. Your provider can also listen for the crackling, bubbling sounds the American Lung Association says pneumonia often makes in the lungs.

What is walking pneumonia?

Walking pneumonia is a milder form of pneumonia, and its name comes from the fact that people often feel well enough to keep going about their day. The American Lung Association describes it as typically a milder infection, commonly caused by a bacterium called Mycoplasma pneumoniae. Early on it can feel like a bad cold or the flu, then settle into a cough that lingers for weeks. It usually does not require a hospital stay, but it is still worth having checked, because it can be treated and because a lingering cough deserves a real diagnosis.

Do you need antibiotics for a cough?

Usually not for bronchitis, and often yes for bacterial pneumonia, which is the whole reason telling them apart matters. Since most acute bronchitis is viral, familydoctor.org from the AAFP notes that antibiotics will not help a typical case. Bronchitis care is supportive: rest, plenty of fluids, a humidifier, and over-the-counter fever reducers. Bacterial pneumonia is the case where antibiotics do the work, so a correct diagnosis keeps you from taking a medicine you do not need or missing one you do.

When is a cough an emergency?

Some breathing symptoms are red flags that mean the emergency room, not a walk-in visit. Emergency physicians point to several warning signs: trouble breathing or shortness of breath, persistent pain or pressure in the chest, sudden confusion or a change in mental status, bluish lips or face, and coughing up or vomiting blood. A high fever that will not come down, or any breathing trouble in a very young infant, also belongs on that list.

For a medical emergency, call 911. If you have any of the warning signs above, do not wait for a clinic to open.

Pneumonia is common and it is serious. The American Lung Association reports that pneumococcal pneumonia hospitalizes an estimated 225,000 adults every year in the United States. Adults 65 and older, infants and toddlers, people with chronic conditions like COPD, asthma, diabetes, or heart disease, smokers, and anyone with a weakened immune system are at higher risk and should be checked sooner rather than later.

Our self-pay pricing is posted up front, with a $130 office visit and a $75 X-ray, and we take most major insurance and file it for you. See our pricing and insurance page, or contact us with questions before you come in.

Frequently asked questions

Can bronchitis turn into pneumonia?
It can. Bronchitis and pneumonia are separate conditions, but an airway infection can sometimes move deeper into the lungs, especially in people at higher risk. If a cough from bronchitis suddenly gets worse, brings a higher fever, or starts causing shortness of breath, that change is a reason to be seen and possibly get a chest X-ray.

How long does bronchitis last?
Acute bronchitis usually runs less than three weeks, with the cough often outlasting the other symptoms. Rest, fluids, and time do most of the work. If your cough drags on beyond about three weeks, or you feel worse instead of slowly better, come in so we can rule out pneumonia or another cause.

Do I need a chest X-ray for a cough?
Not every cough needs one. A chest X-ray is most useful when your provider needs to confirm or rule out pneumonia, for example if you have a fever, shortness of breath, or a cough that will not quit. Our Vancleave clinic has on-site X-ray with same-visit results, so you can find out in one trip.

Is walking pneumonia contagious?
Walking pneumonia is a milder pneumonia most often caused by Mycoplasma pneumoniae, and like other respiratory infections it can spread from person to person. It usually does not require hospitalization, but because it can linger for weeks it is worth having diagnosed so you can treat it and protect the people around you.

Urgent care or the ER for a cough, which one?
For most coughs, a low-grade fever, or a chest cold, a walk-in visit is the right fit and far faster than an emergency room. Head to the ER or dial 911 for true warning signs: serious trouble breathing, chest pain or pressure, confusion, or blue-tinged lips or skin. When in doubt about breathing, choose the ER.
