A n infection of the bronchi that may be indistinguishable from the common cold, often associated with repetitive coughing or sputum production. It is usually caused by viruses (especially rhinoviruses, influenza A or B, parainfluenza, adenoviruses, or respiratory syncytial virus) or less often by Mycoplasma pneumoniae, Chlamydia, streptococci, Haemophilus spp, Moraxella lacunata, Bordetella pertussis, staphylococci.
Acute bronchitis is a type of bronchitis that typically arises suddenly, often as a result of a viral infection, but tends to resolve within a few days. However, it can sometimes lead to bacterial infection of the airways as a complication. Individuals who smoke, infants, the elderly, and those with lung disease are particularly vulnerable to this condition. Symptoms encompass wheezing, shortness of breath, and a cough that produces yellow or green sputum. Additionally, individuals may experience pain behind the sternum (breastbone) and fever.
To alleviate symptoms of bronchitis, it is advisable to consume ample fluids and engage in practices such as steam inhalation or the use of a humidifier. In the majority of cases, no additional treatment is required, as bronchitis tends to resolve on its own. However, acute bronchitis can be severe in individuals who already have pre-existing lung damage.
