Chest Infection – Overview
Chest infection refers to an infection that affects the lungs or large airways, usually caused by viruses or bacteria. It can range from mild bronchitis to more serious pneumonia. While many people recover within a few days or weeks, chest infections can become dangerous, especially in the elderly, children, and those with weakened immune systems.
The two most common types of chest infection are bronchitis and pneumonia. Bronchitis involves inflammation of the bronchial tubes and is typically viral, whereas pneumonia affects the air sacs (alveoli) in the lungs and is more often bacterial.
Symptoms may include a persistent cough (with or without mucus), chest pain or tightness, fever, fatigue, shortness of breath, and wheezing. In some cases, especially in pneumonia, people may also experience rapid breathing, confusion (particularly in older adults), or bluish lips and fingertips due to lack of oxygen.
Chest Infection
Chest infections are more common during winter, when cold and flu viruses are widespread. Smoking, chronic lung conditions, and poor immunity increase the risk of developing a serious infection.
While mild cases can be managed at home with rest, fluids, and over-the-counter medications, more severe infections may require antibiotics or hospital care. Early treatment prevents complications and supports a faster recovery.
Iinfection is a broad term, and understanding its types, causes, and warning signs can help you seek care promptly and reduce the risk of serious illness.
