A chest infection is an infection of the lungs or large airways. Some chest infections are mild and clear up on their own, but others can be severe and life threatening.
Antibiotics aren't recommended for many chest infections, because they only work if the infection is caused by bacteria, rather than a virus. Your GP will usually only prescribe antibiotics if they think you have pneumonia, or you're at risk of complications such as fluid building up around the lungs (pleurisy).
Your doctor may prescribe antibiotics if the symptoms are severe and include high fever along with nasal drainage and a productive cough. Antibiotics may also be necessary if you feel better after a few days and then your symptoms return or if the infection lasts more than a week.
Signs and symptoms of a chest infection
coughing up yellow or green phlegm (thick mucus), or coughing up blood. breathlessness or rapid and shallow breathing. wheezing. a high temperature (fever)
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.
The symptoms of a chest infection are more likely to include coughing and bringing up phlegm. An upper respiratory tract infection may cause a cough, but it can also produce symptoms such as sneezing, a blocked or runny nose and a sore throat. The effects of a chest infection will also tend to last a little longer.
It could be a sign of something more serious, such as bronchitis or pneumonia, so stay at home and call your doctor right away.
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.
The typical antibiotic prescribed for a chest infection is amoxicillin (a type of penicillin). If you are allergic to amoxicillin, alternatives can be used like clarithromycin or doxycycline.
Your doctor will listen to your lungs with a stethoscope. If you have pneumonia, your lungs may make crackling, bubbling, and rumbling sounds when you inhale.
Dozens of conditions can cause a recurrent, lingering cough, but the lion's share are caused by just five: postnasal drip, asthma, gastroesophageal reflux disease (GERD), chronic bronchitis, and treatment with ACE inhibitors, used for high blood pressure and heart failure.
White snot can occur with a cold, for example, and pink boogers can be a sign of pregnancy. And while green or yellow snot may indicate a bacterial infection—and a need for antibiotics—it can also signal that your body is on the mend.
If your cough lasts longer than 3 weeks or isn't getting better after 10 days, you may need antibiotics for your cough.
After 2 or 3 days, mucus may change to a white, yellow, or green color. This is normal and does not mean you need an antibiotic. Some symptoms, especially runny or stuffy nose and cough, can last for up to 10 to 14 days. Those symptoms should improve over time.
A classic sign of bacterial pneumonia is a cough that produces thick, blood-tinged or yellowish-greenish sputum with pus. Pneumonia is an infection that inflames the air sacs in one or both lungs.
Is coughing up phlegm a good thing? Yes. While the presence of mucus may indicate an underlying issue, coughing up phlegm is a good thing because it helps clear irritants, allergens and infections out of your system.
Stage one: Congestion. The first stage of pneumonia occurs around 24 hours after developing an infection in the lungs. It also lasts for about 24 hours. During the congestion stage, the bacteria or virus has taken hold in the lungs and caused an infection.
