Bacterial infection in lung requires long-term antibiotics. Treatment is recommended for people with symptoms and because treatment may reduce ongoing lung damage. The choice of antibiotics depends on the sensitivity of the organism, but one common regimen is clarithromycin, rifampin and ethambutol.
Full Answer
How are chronic lung infections diagnosed and treated?
Since the term “chronic lung infections” is reserved for those that fail to respond to treatment (antibiotics, etc.), the cause of treatment failure is as important as the infectious agent. Diagnosis must include a search for the patient’s underlying host factors, such as age, immunosuppression, and comorbidities.
What is a lung infection?
A lung infection is a condition in which a disease-causing microorganism causes damage and inflammation—due to the gathering of immune cells—in the airways or tissues of the lungs. Lung infections may be caused by viruses, bacteria, fungi, or rarely in the United States, parasites. In some cases, more than one type of microorganism is responsible.
How are chronic lung infections (CLL) prevented?
Prevention of chronic lung infections includes avoiding behaviors that increase risk, immunizations, and societal adjustments. Immunization for influenza and pneumococcus are the most important preventive strategies in prevention of pneumonia, especially for those cloistered in institutionalized settings.
Is a mild lung infection serious?
Lung infections like pneumonia are usually mild, but they can be serious, especially for people with weakened immune systems or chronic conditions, such as chronic obstructive pulmonary disease (COPD). Read on to learn the most common symptoms of a lung infection and what treatment you can expect if you have one.
What is a long term lung infection?
What Are Chronic Lung Infections? Chronic lung infections are those which do not resolve quickly or at all after antibiotic treatment. The most common causes are from chronic obstructive pulmonary disease (COPD), cystic fibrosis, and bronchiectasis, all of which involve inability to clear secretions.
What are some infectious lung diseases?
Lung diseases affecting your alveoli include:Pneumonia. ... Tuberculosis Pneumonia that slowly gets worse, caused by the bacteria Mycobacterium tuberculosis.Emphysema. ... Pulmonary edema. ... Lung cancer. ... Acute respiratory distress syndrome (ARDS). ... Pneumoconiosis.
What is emphysema disease?
Emphysema is a lung condition that causes shortness of breath. In people with emphysema, the air sacs in the lungs (alveoli) are damaged. Over time, the inner walls of the air sacs weaken and rupture — creating larger air spaces instead of many small ones.

What is the treatment for lungs infection?
Antibiotics are the mainstay of treatment for bacterial lung infections, with different antibiotics recommended depending on the particular type of infection and suspected organism. The choice of using oral antibiotics versus intravenous treatment will depend on the severity of the infection.
What is an infectious disease?
Infectious diseases are disorders caused by organisms — such as bacteria, viruses, fungi or parasites. Many organisms live in and on our bodies. They're normally harmless or even helpful. But under certain conditions, some organisms may cause disease. Some infectious diseases can be passed from person to person.
Is COPD the same as emphysema?
Emphysema is a type of COPD (chronic obstructive pulmonary disease). COPD is a group of lung diseases that make it hard to breathe and get worse over time. The other main type of COPD is chronic bronchitis.
What's the difference between COPD and emphysema?
Emphysema is one type of COPD disease. It damages the air sacs in the lungs, making it progressively harder for the body to get the oxygen it needs. The term COPD also covers chronic bronchitis and asthma. A person with emphysema has COPD, but a person with COPD may not necessarily have emphysema.
What causes COPD?
Smoking. Smoking is the main cause of COPD and is thought to be responsible for around 9 in every 10 cases. The harmful chemicals in smoke can damage the lining of the lungs and airways. Stopping smoking can help prevent COPD from getting worse.
What is a lung disease called?

Differences Between the Most Common Respiratory Infections. Four of the most common types of respiratory infections are COVID-19, the flu, pneumococcal disease, and colds.
Preventing Infectious Respiratory Diseases
Get Vaccinated. Talk to your doctor to see if you are up to date on your vaccinations. It’s always better to prevent a disease rather than treat it after it occurs.
Treating Infectious Respiratory Diseases
While each disease has slightly different symptoms, diagnostic tests, and treatment options, these overarching concepts provide a broad overlay for treatment.

The most common causes are from chronic obstructive pulmonary disease (COPD), cystic fibrosis, and bronchiectasis, all of which involve inability to clear secretions.
What are the respiratory changes that can begin lengthy (chronic) lung infections?
Depending on specific illnesses or the degree of debilitation, the respiratory changes that can begin lengthy (chronic) lung infections include: Loss of elastic recoil in the chest wall resulting in air trapping and increase in lung capacity and residual volume. Diminished respiratory muscle strength and endurance. Loss of alveoli.
Why are lung infections confusing?
Although different chronic lung infections are caused by different agents, they can be confusing because of similarities in their signs, symptoms, X-ray findings, and pulmonary compromise. The end result is a common syndrome whose cause may be difficult to identify specifically unless further testing is used.
What are the respiratory changes?
Depending on specific illnesses or the degree of debilitation, the respiratory changes that can begin lengthy (chronic) lung infections include: 1 Loss of elastic recoil in the chest wall resulting in air trapping and increase in lung capacity and residual volume 2 Diminished respiratory muscle strength and endurance 3 Loss of alveoli 4 Reduction in oxygen and carbon dioxide exchange 5 Inability to increase rate of respiratory effort 6 Decreased cough or gag reflex (leading to ineffective clearance or aspiration pneumonia 7 Decreased ability of cilia to move mucous and bacterial debris upward
Why are immunocompromised people ineffective?
Those who are immunocompromised (e.g., HIV) are who are pharmacologically immunocompromised (systemic corticosteroid use) may be ineffective in the first lines of defense due to limitations of the innate immune system.
What is the treatment for a fungal infection?
Fungal infections are treated with antifungal agents. Viral infections of the lung which fail to resolve are typically due to immunocompromise, so treatment will involve both antiviral agents and reduction of any immunosuppression.
What test is used to determine the severity of an infection?
Blood tests : helpful in identifying the severity of infection via a white blood count and even an allergic or parasitic component based on eosinophils (WBCs common in allergic reactions and parasites). Pulmonary function testing: to evaluate the degree of lung compromise with functional testing such as spirometry.
What is the best treatment for a fungal lung infection?
A fungal lung infection will require treatment with an antifungal medication, such as ketoconazole or voriconazole. Antibiotics won’t work on viral infections.
What is it called when you have a virus in your lungs?
When the large bronchial tubes that carry air to and from your lungs become infected, it’s referred to as bronchitis. Bronchitis is more likely to be caused by a virus than by bacteria. Viruses can also attack the lungs or the air passages that lead to the lungs. This is called bronchiolitis.
How do you know if you have a lung infection?
If you have a lung infection, here are the most common symptoms to expect: 1. Cough that produces thick mucus. Coughing helps to rid your body of the mucus produced from inflammation of the airways and lungs.

Can a viral lung infection last longer?
A lung infection causes symptoms similar to the cold or flu, but may be more severe and typically last longer . Your immune system will typically be able to clear a viral lung infection over time. Antibiotics are used to treat bacterial lung infections. See your doctor right away if you have:
Overview
A group of bacteria called Mycobacterium avium complex (MAC) causes MAC lung disease. Most people who breathe in or swallow these germs don’t get sick. But some pre-existing conditions can make some people more susceptible to developing a slow-growing infection once MAC enters their airway.
Symptoms and Causes
MAC bacteria naturally reside in soil and water. Stirring up soil or dust can make the bacteria airborne, and you may breathe them in. People who garden or work with soil have slightly more MAC than those who don’t. MAC is also in water, including the water in your home.
Diagnosis and Tests
Your healthcare provider will perform a physical exam and ask about symptoms.
Management and Treatment
Because MAC lung disease is difficult to get rid of, you may see an infectious disease or a pulmonary specialist. Both specialties have expertise in diagnosing and treating infections.
Prevention
Avoid hot tubs and saunas that recirculate hot, steamy water if your provider feels they may have been the source of your MAC bacteria.
Frequently Asked Questions
While you can’t catch a MAC infection from someone else, the condition sometimes affects more than one family member. Experts believe certain people have a genetic change (mutation) that makes them more susceptible to MAC infections.
What is lung disease?
