Although most common chest infections will clear up without treatment, if the infection is particularly severe or symptoms do not begin to ease within 2–3 weeks, it may be time to see a doctor. Other symptoms that also indicate it is time to see a doctor include: coughing up blood or bloody mucus.
A chest infection will either be caused by: a virus (like viral bronchitis) – this usually clears up by itself after a few weeks and antibiotics will not help. bacteria (like pneumonia) – a GP may prescribe antibiotics (make sure you complete the whole course as advised by the GP, even if you start to feel better)
With rest, sleep and plenty of water, you should start feeling better within 10 days without needing antibiotics. However, symptoms of the common cold, flu and more severe chest infections can overlap making it difficult to self-assess your condition.
The symptoms of viral and bacterial chest infections are similar but the colour of any mucus coughed up may indicate the cause; white or clear mucus usually indicates a viral infection whereas green or yellow mucus suggests that the infection is bacterial.
Pneumonia can be life-threatening if left untreated, especially for certain at-risk people. You should call your doctor if you have a cough that won't go away, shortness of breath, chest pain, or a fever. You should also call your doctor if you suddenly begin to feel worse after having a cold or the flu.
Pneumonia has four distinct stages of infection: Congestion, red hepatization, gray hepatization, and resolution. Keep in mind that everyone who gets pneumonia will have a different experience. You may not follow the same timeline or have the same symptoms in each stage.
If you have a bacterial chest infection, you should start to feel better 24 to 48 hours after starting on antibiotics. You may have a cough for days or weeks. For other types of chest infections, the recovery is more gradual. You may feel weak for some time and need a longer period of bed rest.
Signs and symptoms of a chest infection
The main symptoms of a chest infection can include: a persistent cough. coughing up yellow or green phlegm (thick mucus), or coughing up blood. breathlessness or rapid and shallow breathing.
If your bronchitis is caused by a virus, you can be contagious for a few days to a week. If your bronchitis is caused by bacteria, you usually stop being contagious 24 hours after starting antibiotics. Other causes of bronchitis aren't contagious.
Even if you're coughing up yellow or green phlegm, you might not need antibiotics. Your mucus color alone can't tell you if a virus or bacteria is causing your cough. If your cough lasts longer than 3 weeks, it's time to see a healthcare provider. You may need an X-ray or antibiotics.
What does a pneumonia cough sound like? This will depend on the type of pneumonia you have and be either a dry or chesty cough. Bacterial pneumonia is more serious and often results in a gurgling sound when breathing and mucus or phlegm when coughing.
Mucus: The Warrior
Coughing and blowing your nose are the best ways to help mucus fight the good fight. “Coughing is good,” Dr. Boucher says. “When you cough up mucus when you are sick, you are essentially clearing the bad guys—viruses or bacteria—from your body.”
A bronchitis cough sounds like a rattle with a wheezing or whistling sound. As your condition progresses, you will first have a dry cough that can then progress towards coughing up white mucus.
See a doctor if you have any of the following: Temperature of 100.4 °F or higher. Cough with bloody mucus. Shortness of breath or trouble breathing.
Pneumonia is inflammation of the lungs, usually caused by an infection. Most people get better in 2 to 4 weeks, but babies, older people, and people with heart or lung conditions are at risk of getting seriously ill and may need treatment in hospital.
The associated cough and mucus can last up to three weeks. If your chest infection is taking longer to shift, or it seems to be getting worse, it is really important to contact your GP. If you have already had antibiotics and they have not worked, don't be afraid to ask for an x-ray, or even a CT scan, like Ruthra.
