Coughing, wheezing, and struggling to catch your breath — bronchitis can turn a simple cold into something much more uncomfortable. But beyond the symptoms, one question often comes to mind: Is bronchitis contagious?
With respiratory illnesses often spreading in workplaces, schools, and homes, it’s important to know how bronchitis works so you can protect yourself. So, let’s explore what bronchitis is, how long it lasts, how to prevent it, and whether you should worry about catching it from others.
What Is Bronchitis?
Bronchitis occurs when the bronchial tubes — the passages responsible for carrying air to the lungs — become inflamed. This inflammation results in swelling, mucus buildup, and even difficulty breathing, often accompanied by a persistent cough.
There are two main types of bronchitis: acute and chronic. Acute bronchitis is a temporary condition usually caused by viral or bacterial infections. It typically lasts for a few weeks and often develops after a cold or the flu. Chronic bronchitis is a more long-term condition, with symptoms lasting for several months or longer. Chronic bronchitis is often linked to smoking or extended exposure to irritants like pollution. Along with emphysema, chronic bronchitis is considered a form of chronic obstructive pulmonary disease (COPD).
