Acute Bronchitis Infection: Viral Cough Condition Information Guide
Summary
Acute bronchitis is a common condition that inflames the airways in your lungs, leading to a persistent cough. Usually caused by a virus, it often starts with a dry cough that becomes more productive, meaning you might start coughing up mucus. Other symptoms can include mild fever, tiredness, and difficulty breathing. This condition typically resolves on its own within 2-3 weeks. While antibiotics don't help with viral bronchitis, taking care of yourself at home can ease your symptoms.
What Is This & Why It Matters
Acute bronchitis happens when the tubes that carry air to your lungs become swollen and irritated. This swelling makes it hard for air to move in and out of the lungs, causing a cough. Most cases are due to viruses, which means they can't be treated with antibiotics. Instead, the focus is on relieving symptoms and supporting your body's recovery. According to ACEP 2024 guidelines, conservative management is recommended, emphasizing rest and hydration.
What You Should Do
- Stay hydrated by drinking plenty of fluids like water and herbal teas.
- Rest as much as possible to help your body fight the infection.
- Use a humidifier or inhale steam from a hot shower to soothe your throat.
- Gargle with warm salt water to ease throat irritation.
- Take over-the-counter medications like acetaminophen for fever and pain relief.
- Keep your head elevated while sleeping to reduce nighttime coughing.
What You Should NOT Do
- Avoid smoking or exposure to secondhand smoke, which can worsen symptoms.
- Don't take antibiotics unless prescribed by a doctor; they're ineffective against viruses.
- Refrain from overusing cough suppressants; they can prevent clearing mucus from your lungs.
- Avoid strenuous activities that can strain your breathing.
- Don't ignore worsening symptoms; consult a doctor if they occur.
