A cough that lingers for weeks after a cold has cleared is one of the most common reasons patients end up at a chest medicine consultation — and more often than not, it turns out to be bronchitis rather than the cold itself dragging on. Alliance Hospital BD’s One Stop Respiratory Center in Shyamoli provides complete diagnosis and treatment for both acute and chronic bronchitis, for patients across Shyamoli and nearby Mohammadpur.
This guide explains the difference between acute and chronic bronchitis, how each is treated, and when it’s time to see a specialist.
Bronchitis is inflammation of the bronchial tubes, the airways that carry air to and from the lungs. It comes in two distinct forms that are treated quite differently. Acute bronchitis is usually caused by a viral infection, often following a cold or flu, and typically resolves on its own within one to three weeks. Chronic bronchitis, on the other hand, is a long-term condition defined by a persistent cough with mucus production on most days for at least three months, generally linked to smoking or long-term exposure to irritants, and is considered a form of COPD.
According to the NHS’s overview of bronchitis, a cough from acute bronchitis can linger for several weeks even after other symptoms have cleared, which is normal but still worth mentioning to a doctor if it doesn’t gradually improve.
These signs can point to a more serious infection, an underlying condition like COPD, or in rare cases something requiring urgent attention. Alliance Hospital’s Accidental & Emergency Center in Shyamoli operates 24 hours with direct access to the chest medicine team when needed.
Diagnosis usually starts with a physical examination and a review of symptom history, particularly how long the cough has lasted and how often it recurs. A chest X-ray may be used to rule out pneumonia or other conditions, and pulmonary function testing can help distinguish chronic bronchitis from other respiratory conditions like asthma when the pattern isn’t clear.
Since acute bronchitis is usually viral, antibiotics generally aren’t effective or necessary. Treatment focuses on rest, hydration, and symptom relief — cough suppressants or expectorants where appropriate, and fever-reducing medication if needed. Most cases resolve fully within a couple of weeks without lasting effects.
Chronic bronchitis requires a longer-term management approach, since it reflects ongoing airway inflammation rather than a passing infection. Treatment typically includes bronchodilator inhalers to ease breathing, and in some cases inhaled corticosteroids to reduce inflammation. Pulmonary rehabilitation — a structured program of exercise training and breathing techniques — often meaningfully improves day-to-day symptoms.
Quitting smoking is central to managing chronic bronchitis. Since ongoing irritant exposure is usually what’s driving the inflammation, continued smoking or exposure tends to undermine any other treatment. Stopping is the single step most likely to slow progression and reduce symptoms.
For acute bronchitis, good hygiene practices — regular handwashing, avoiding close contact during respiratory illness, and staying up to date on vaccinations — reduce the risk of the viral infections that typically cause it. For chronic bronchitis, avoiding smoking and long-term exposure to dust, fumes, or air pollution is the most effective preventive step, alongside prompt treatment of any respiratory infections that do occur.
Alliance Hospital’s Chest Medicine department is led by Prof. Dr. Md. Rashidul Hasan, holding an MD in Chest Diseases, with extensive experience distinguishing and managing both acute and chronic respiratory conditions.

Patients from Mohammadpur, Adabor, and Kallyanpur can reach the One Stop Respiratory Center within a short drive given its location just off Ring Road in Shyamoli, with the same diagnostic testing and treatment options available near Mohammadpur.
Dealing with a lingering cough or recurring chest infections? Alliance Hospital’s Chest Medicine team in Shyamoli can help identify the cause and get you the right treatment.
Acute bronchitis, since it’s usually caused by a virus, can be contagious in the same way a cold or flu is. Chronic bronchitis, caused by long-term irritant exposure rather than infection, is not contagious.
Usually not. Most acute bronchitis is viral, so antibiotics won’t help and aren’t typically prescribed unless a secondary bacterial infection is suspected.
Acute bronchitis typically resolves within one to three weeks, though a lingering cough can persist a bit longer even after other symptoms clear. Chronic bronchitis is an ongoing condition requiring long-term management.
In some cases, an untreated or severe respiratory infection can progress to pneumonia, which is part of why a cough that’s worsening rather than improving should be evaluated by a doctor.
Chronic bronchitis is considered one of the two main forms of COPD (alongside emphysema), so it’s typically managed as part of an overall COPD treatment plan rather than as a separate condition.
