Therefore, yellowish or green sputum may be a normal feature in patients with viral bronchitis. Also, sputum production in viral airway infections may be clear, white, or even tinged with blood [15].
Small amounts of white mucus may be coughed up if the bronchitis is viral. If the color of the mucus changes to green or yellow, it may be a sign that a bacterial infection has also set in. The cough is usually the last symptom to clear up and may last for weeks.
Changes in mucus color, from clear to white to yellow to green, are part of the normal course of an illness. It's a sign that your immune system is fighting to get better. Pink, red, orange, or brown snot, on the other hand, is typically not from an illness.
Clear snot is in the normal range, while white mucus can mean you're congested and yellow or green mucus can sometimes mean that you have an infection.
Red or pink phlegm can be a more serious warning sign. Red or pink indicates that there's bleeding in your respiratory tract or lungs. Heavy coughing can cause bleeding by breaking the blood vessels in the lungs, leading to red phlegm.
Green and cloudy: viral or bacterial infection
A lot of the symptoms of viral infections – fever, cough, headache, loss of smell – overlap for COVID-19 and other viral infections like the flu, respiratory syncytial virus and the common cold.
Common symptoms of pneumonia include: a cough – which may be dry, or produce thick yellow, green, brown or blood-stained mucus (phlegm)
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.
Does coughing up mucus mean you're getting better? In most cases, coughing up mucus means your body is working to fight off an infection, and it is in the healing stages. Drink plenty of fluids to help thin the mucus.
Signs and symptoms of a chest infection

Brown and black. Brown phlegm may indicate possible bleeding. While it is likely due to bleeding that happened a while ago, it can also indicate a chronic infection such as bronchitis. People who smoke may also have brown phlegm.
Instead, your doctor looks largely at symptom duration to determine the source of your infection. A viral sinus infection will usually start to improve after five to seven days. A bacterial sinus infection will often persist for seven to 10 days or longer, and may actually worsen after seven days.
Check if you have a chest infection
Chest infections often follow colds or flu. The main symptoms are: a chesty cough – you may cough up green or yellow mucus.
When you do cough up phlegm (another word for mucus) from your chest, Dr. Boucher says it really doesn't matter if you spit it out or swallow it.
One of the first signs of a cold is green or yellow mucus. It's no reason for concern, and in fact, it means your body is working extra hard to fight off infection. White blood cells rush to battle infection, and when they've done their job, they get flushed out of the body along with the virus.
These four stages of pneumonia are congestion, red hepatization, gray hepatization, and resolution, respectively.
A dry cough is one of the most common coronavirus symptoms, but some people may have a cough with phlegm (thick mucus). It can be difficult to control your cough but there are a few ways to help.
Bronchitis is an infection of the main airways of the lungs (bronchi), causing them to become irritated and inflamed. The main symptom is a cough, which may bring up yellow-grey mucus (phlegm). Bronchitis may also cause a sore throat and wheezing.
The virus life cycle can be divided into three stages—entry, genome replication, and exit (Fig. 3.1 ).
Some symptoms, especially runny or stuffy nose and cough, can last for up to 10 to 14 days.
Even if mild symptoms remain, you are likely not contagious after 10 days.
If you cough up phlegm that's yellow, green, brown, black, white or red — or if you cough up mucus for two weeks or longer, schedule a visit with your healthcare provider. They can find out what's causing you to cough up phlegm and treat any underlying conditions.
