Types of Chest Infections
The most common types of chest infections include pneumonia and bronchitis. While tuberculosis is common worldwide, it’s not as common in the United States.
Bronchitis
Bronchitis is inflammation of the bronchi, the tubular structures that bring air in and out of the lungs. There are two main types of bronchitis: acute (short term) and chronic (persisting or constantly recurring).
Risk factors include:
Having a cold or other viral respiratory tract infectionChronic sinus infectionsAllergiesEnlarged tonsils
Most people who develop acute bronchitis don’t need medical intervention. However, people with certain conditions like existing heart or lung diseases should talk to a healthcare provider if they think they have or might develop bronchitis.
Pneumonia
In some people, bronchitis can develop into a more serious infection called pneumonia, which is an infection of one or both of the lungs. People at higher risk of getting pneumonia include:
Older adultsInfants under 24 monthsSmokers People with underlying medical conditions
Chest Infection Symptoms
Here are some of the symptoms of certain chest infections.
Bronchitis
Symptoms of acute bronchitis may include:
Body achesCoughing that starts off dry then eventually produces mucusMild fever and chillsFatigueRunny noseBreathing issuesSore throat
Pneumonia
Symptoms of pneumonia include:
Blue tinge to the lips and fingernail bedsConfusionCoughing that produces mucusFever and chillsExtreme fatigueRapid heartbeatLoss of appetite Chest pain when breathing in or coughingBreathing issues
Symptoms may vary depending on the individual and the type of pneumonia they have.
Mycoplasma pneumonia, or walking pneumonia, is the mildest form of this type of infection. It often presents similarly to the common cold.
Tuberculosis (TB)
This airborne bacterial infection mainly affects the lower respiratory tract. Symptoms of tuberculosis include:
Chronic cough that lasts longer than three weeksFever and chillsLoss of appetite Weight lossNight sweats
Some people may also cough up blood.
Causes
Acute bronchitis is usually the result of a virus, but it can be bacterial in origin. Irritants also can cause acute bronchitis. Pneumonia has many different potential causes. Bacteria, viruses, and fungi may all cause pneumonia. TB is a bacterial infection caused by a specific bacterium called Mycobacterium tuberculosis.
Diagnosis
Healthcare providers will perform a physical exam and take a medical history to diagnose bronchitis. Your healthcare provider may order a chest X-ray to check for pneumonia. A sputum culture can help determine whether the infection is bacterial or viral.
If your healthcare provider suspects you have pneumonia, you may be asked to get a computed tomography (CT) scan of your chest, a bronchoscopy (a procedure to look directly into your lungs and air passages), and blood tests.
If TB is a possibility, tests to confirm the diagnosis include:
Skin testsBlood testsChest X-ray or CT scan Sputum culture
Some of these tests can take weeks to produce results.
Treatment
Most chest infections, including bronchitis, don’t produce complications. If bronchitis occurs because of a virus, antibiotics won’t help fight the infection.
Healthcare providers may use antibiotics to treat a bacterial infection that has developed into pneumonia. Viral pneumonia typically clears up on its own in an otherwise healthy person.
At-home treatment strategies to manage symptoms include:
Taking over-the-counter (OTC) cough medicineUsing a humidifierHydrating to thin out mucusGetting lots of rest
Pneumonia is also treated with similar strategies, but depending on the cause, the severity of the case, and your underlying health, it may need to be treated with prescription drugs or even hospitalization and breathing support. Antibiotics may be prescribed for bacterial pneumonia, antiviral medications for influenza, and antifungal medications for pneumonia caused by fungal infections.
Treatment for TB depends on whether the infection is active or latent. In people infected with TB but with no active infection, the treatment is preventative and involves taking an antibiotic called isoniazid for up to nine months.
If the infection is active, treatment involves taking antibacterial medications for up to a year. It’s crucial to take the whole course of medication to prevent treatment-resistant TB.
A Word From Verywell
We’ve all dealt with the common cold at some point. Even a mild cold can drag a person down for days. Most people get over a cold without issue. Sometimes, though, the viral infection can progress, move into the lower respiratory tract, and cause more pronounced symptoms.
Chest infections, whether viral, bacterial, or fungal in origin, will often go away with proper at-home treatment—and lots of rest. However, if your symptoms are not going away or are getting worse, you should talk to your healthcare provider. Sometimes people with chest infections require medical treatment.
If you have underlying medical conditions, are over the age of 65, or have a compromised immune system, tell your healthcare provider if you’re experiencing any respiratory symptoms. Parents of very young children should get in touch with their pediatrician if you notice your child is sick and experiencing signs of a respiratory tract infection.
