Lung infections caused by viruses, fungi, or bacteria are common and can be triggered by asthma, bronchitis, pneumonia, or tuberculosis. Infections weaken lung tissue, making it susceptible to harmful particles. Treatment depends on the severity and type of infection and may require antibiotics or other medication. Precautions such as hand washing and avoiding contact with sick people are important to prevent the spread of infection.
A lung infection is inflammation in or around the lung tissue caused by a virus, fungus, or bacteria. There are a number of things that can trigger this type of problem, but the four most common tend to be asthma, bronchitis, pneumonia and tuberculosis. The lungs are usually very moist, making them an ideal breeding ground for a number of harmful things. Their tissues are also very sensitive and prone to damage from particles that are inhaled or otherwise introduced. Healthy people can normally ward off infections in the lungs and elsewhere as a regular function of the immune response, but problems are much more likely when lung tissue is already weakened, whether by lifestyle or environmental reasons such as smoking or alcohol. air pollution or for things like sickness and respiratory weakness. Most infections are treatable, but success often depends on how quickly the problem is detected and how widespread it is. Simple cases can often be resolved with a single course of medication, but more advanced infections often require powerful prescription drugs and other sometimes invasive treatments.
Basic strokes
The lungs are one of the central parts of the human respiratory system, supplying oxygen to the blood and most parts of the body. This system also includes the nasal cavity, pharynx and trachea. Infections that start anywhere in the respiratory tract can quickly spread to the lungs and vice versa.
There are many different types of infections, each with its own cause and basic characteristics. In most cases, however, they begin when some form of irritant causes a weakening of a portion of the lung tissue that makes that tissue more susceptible to bacteria, viruses, or infection. People commonly inhale problematic particles, and a number of harmful bacteria float around the bodies of healthy people from time to time as well. Infections typically only occur if they find a place to attach themselves and begin to regenerate.
Asma
Asthma is a chronic inflammatory disease that blocks the airways and is one of the most common causes of lung infections, particularly in children. The cause of the condition is threefold. In most people it is a convergence of bronchial edema, increased mucus and constriction of the bronchi.
Signs and symptoms of asthma include tightness in the chest, wheezing, coughing and wheezing. Some of the biggest environmental triggers are mold, mildew, seasonal pollen, and certain foods. Some conditions, such as gastroesophageal reflux disease (GERD) and allergic rhinitis, also contribute to asthma attacks. Asthma-related infections are usually treated with inhaled inflammatory agents such as bronchodilators and glucocorticoids.
Bronchitis
Bronchitis is an inflammation of the lung tissue caused by a virus or bacterium and is another very common source of infection. It is usually caused by inflammation of the airways, and the infection occurs when the windpipe and bronchi in the lungs swell, usually from a cold or other viral attack. The incubation period for the infection is typically four days after the inciting illness. Bronchitis is often seen in both adults and children.
Pneumonia
Pneumonia is an acute inflammation of the lungs and is sometimes referred to as an acute respiratory tract infection of the alveoli. This condition is often caused by bacteria, viruses, fungi and staphylococci. Pneumonia ranges from mild to severe and can sometimes be life-threatening. It is seen most often in elderly patients and young children, although it can affect anyone. Antibiotics are one of the most common things doctors use to treat these types of infections, but there are some strains of pneumonia that are resistant to most antibiotics.
Tuberculosis
Tuberculosis is one of the most serious lung diseases a person can get. It is a serious lung infection caused by mycobacterium tuberculosis. The lungs are usually the main organ affected, but the infection can and often does spread. The early stages of the condition usually have no identifiable symptoms and are usually only detected during a chest X-ray or tuberculosis skin test.
Once set up though, it’s usually pretty obvious. Symptoms of progressive tuberculosis include cough, night sweats, back pain and weight loss. The condition is highly contagious and is spread through the sputum coughed up by infected people. Those who have contracted the disease are often placed in quarantine and usually have to undergo an intensive battery of drugs, including antibiotics, to make the symptoms subside.
Treatment options and precautions
Many lung infections are treatable and even curable, but most require prompt medical attention. They rarely go away on their own, partly because of how easily bacteria and viruses thrive in moist tissue, but also because of how quickly problems can spread from the lungs and other parts of the body. People who are having trouble breathing or have a lot of chest pain are usually advised to get medical help, particularly if they have a history of respiratory infections or have recently suffered from a cold or flu.
Lung infections are often very serious and many are contagious. It is important for people to avoid other people who are sick with these types of infections. If it is necessary to be around him, health precautions should be taken, such as washing his hands often and avoiding direct contact with the sick person. Hand sanitizer should be kept on hand for places that don’t have easy access for hand washing.
