Chest infections are common respiratory illnesses that affect the lungs and the airways. Chest infection occurs when microorganisms like bacteria, viruses, or fungi invade the chest, and irritate the lining of the lungs which leads to inflammation. This illness happens all over the world, and can affect anyone from adults to children, most especially during the cold and flu season.
Types of Chest Infection
As mentioned earlier, chest infection can happen because of a fungi, bacteria, or viruses invasion in the chest, which means that there are different types of chest infections, and each one of them has its own symptoms.
- Pneumonia: Pneumonia is a serious lung infection caused by bacteria, viruses, or fungi. It causes high fever, cough, and then trouble breathing to stop.
- Bronchitis: Bronchitis is one of the chest infections which affects the bronchial tubes in the lungs, making them inflamed. This is usually caused by a virus (influenza virus, rhinovirus, coronavirus, or respiratory syncytial virus (RSV)), and it can lead to cough, mucus production, and discomfort in the chest.
While pneumonia and bronchitis are the most common types of chest infections, they are not the only types of chest infections. There are other types of chest infections like tuberculosis (TB), bronchitis, lung abscess, and empyema.
Symptoms of Chest Infection
- Dry cough
- Shortness of breath
- Chest pain
- Fever
- Tiredness
- Wheezing (high-pitched sound when you breathe)
- Thick mucus when you cough
Causes of Chest Infection
Infection: The number one cause of chest infection is being infected by germs like bacteria, viruses, and fungi. Once any of these germs get into your body system, they invade your lungs or airways, causing what can be some of the most uncomfortable symptoms of chest infections.
Health Conditions: There are some existing health conditions like asthma or chronic obstructive pulmonary disease (COPD), that basically make it more likely for you to get a chest infection. Conditions like that make your lungs more sensitive and less able to fight off infections.
Weak Immune System: If your immune system is weakened, your body will struggle to protect you from illnesses, such as those that cause chest infections. A weakened immune system is frequently brought on by health conditions such as autoimmune disease or by treatments that weaken the immune system.
Irritants: Being exposed to irritants like cigarette smoke or air pollution irritates and inflames the lining of the airways, making it easier for germs to get into your system and cause problems.
Age and Lifestyle: Older people or people with unhealthy lifestyles like regular smoking, are more likely to get a chest infection. As you age, it’s only normal for your immune system to get weaker. On the other hand, unhealthy habits can further weaken your immune system, reducing the body’s ability to fight off infections.
Bottom Line
Chest infections are common respiratory illnesses that affect your breathing, especially during cold and flu season.
Pneumonia and bronchitis are the most well-known types of chest infections, but there are others like tuberculosis (TB) and lung abscesses. There are a few key things that can increase your chances of getting a chest infection such as conditions like asthma or COPD, or exposure to irritants like smoke or pollution etc.
