bronchitis with fever

Overview

Bronchitis is swelling of the tubes that carry air to and from your lungs. When you also have a fever, it usually means there is an infection causing the swelling.

Yes, bronchitis is very common, especially during the colder months.

Anyone can get bronchitis, but it affects smokers, people over 40, and those with weak immune systems more often.

Symptoms

Common symptoms

• A cough that may bring up mucus
• Fever (temperature above 100.4°F or 38°C)
• Chest tightness or aching
• Shortness of breath
• Wheezing (a whistling sound when breathing)
• Tiredness and body aches

Symptoms in children

• Higher fevers than adults often have
• More frequent coughing, especially at night
• Trouble feeding or drinking because of coughing
• Fussiness or irritability

Symptoms in older adults

• Less obvious fever – may only feel warm or have a low temperature
• Confusion or being less alert than usual
• Weakness and trouble walking
• Loss of appetite

Causes

Main causes

• Viral infections (e.g., cold, flu, RSV)
• Bacterial infections (less common)
• Inhaling lung irritants like smoke or fumes

Risk factors

• Smoking or being around smoke
• Having asthma or COPD
• Weak immune system (from age, illness, or medicines)
• Living in crowded or damp conditions

When to see a doctor

See a doctor urgently if:

• You have any of the emergency symptoms listed above.
• Fever does not go down after 3 days of home care.
• You have a lung condition like asthma and your symptoms get worse.

Book a routine appointment if:

• Cough lasts more than 3 weeks after fever is gone.
• You get bronchitis often (several times a year).
• You have a chronic health condition and want a check-up.

Diagnosis

A doctor will ask about your symptoms and listen to your lungs with a stethoscope. They may also check your oxygen level and temperature.

Tests that may be done

• Chest X-ray (to rule out pneumonia)
• Sputum culture (testing the mucus you cough up)
• Pulse oximetry (clip on your finger to measure oxygen)

What to expect at your appointment

The exam is quick and painless. If you have a fever, the doctor may also do a flu or COVID-19 test.

Treatment

Treatment focuses on easing your symptoms while your body fights the infection. Most cases do not need antibiotics.

Self-care at home

• Get plenty of rest.
• Drink lots of fluids (water, warm tea, clear soups).
• Use a humidifier or breathe steam from a hot shower to soothe your airways.
• Avoid smoke and strong fumes.

Medical treatments

Over-the-counter pain and fever reducers can help with fever and body aches. Your doctor may suggest inhalers or cough medicines to help open your airways. If a bacterial infection is found, antibiotics may be prescribed. Always use medicines as directed by your doctor.

When is surgery considered?

Surgery is not needed for bronchitis with fever.

Living with this condition

During the illness, take it easy. Stay home from work or school to rest and avoid passing the infection to others. Wash your hands often and cough into your elbow.

Lifestyle tips

• Quit smoking – it is the single best step you can take.
• Avoid lung irritants like dust, strong cleaners, and secondhand smoke.
• Get plenty of sleep to keep your immune system strong.

Diet and exercise

Eat a balanced diet with fruits and vegetables. While you are sick, rest; as you recover, start with gentle activities like short walks. Walking can help clear your lungs.

Mental health and emotional wellbeing

Feeling tired and coughing a lot can make you feel frustrated or down. It is normal to be anxious about your breathing. Talk to your doctor if your mood does not improve as you get better.

Prevention

You cannot always prevent bronchitis, but you can lower your risk by washing hands often, avoiding sick people, and not smoking.

Vaccines

Flu and pneumonia vaccines can help prevent infections that lead to bronchitis. Ask your doctor which vaccines are right for you.

Screening programmes

No routine screening tests are needed for bronchitis.

Complications

If left untreated

• Pneumonia (infection spreads to the air sacs in your lungs)
• Chronic bronchitis (long-term inflammation and cough)
• Worsening of asthma or COPD

Long-term outlook

Most people with bronchitis and fever get better fully within 1 to 3 weeks. Even if it feels slow, your body is healing. With rest and care, the outlook is very good.
