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.
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.
Can you confirm? ANSWER: Greenish-gray or yellowish nasal mucus — your health care provider might call it purulent nasal discharge — isn't a sure sign of a bacterial infection, although that is a common myth — even in the medical world.
Yellow mucus or green mucus for longer than two weeks accompanied by pain and pressure in your sinuses and face. These symptoms may indicate a sinus infection.
For adults – seek medical attention if:
Your nasal discharge is yellow or green and you also have sinus pain or fever. This may be a sign of a bacterial infection. You have blood in your nasal discharge or a persistent clear discharge after a head injury.
The yellow color comes from the cells — white blood cells, for example — rushing to kill the offending germs. Once the cells have done their work, they're discarded in your snot and give it a dark yellowish tinge. Your illness may last anywhere from 10 to 14 days, but keep an eye on your nasal discharge.
Sindwani says. “Usually after about seven days, if you have that yellow or green snot, and you're not feeling well, that's when we might consider giving you a course of antibiotics.”
Days 3 to 5: Cough and More Nasal Congestion
You may notice that mucus from your runny nose has become thicker, with a yellow or green tinge. This usually is due to a spike in the number of white blood cells your immune system has dispatched to overcome the virus, according to the Mayo Clinic.
When you have a cold or other respiratory illness, you might see a range of different colours of mucus or snot when you blow your nose. We're often told – even by doctors – that green or yellow secretions indicate you're infectious. But this isn't true.
Seasonal allergies are a good example. They can cause all sorts of nasal discharge — thick or thin, yellow, green, or clear — even though there's no infection at all.
Testing. A lab test is the only ironclad way to determine if you truly need an antibiotic. A physician can collect a sample of bodily gunk (whatever you can cough up or blow out of your nose) or take a throat swab. In general, a culture, in which bacteria are grown in the lab and tested, can take a day or two.
Clear or white mucus often indicates a viral infection, while yellow or green mucus may suggest a bacterial infection. The biggest difference between viral and bacterial bronchitis is treatment, as antibiotics used to treat bacterial infections don't kill viruses.
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.
Yellow phlegm is a sign that your body is fighting off a mild infection. "White blood cells are responsible for fighting infections, and as they get picked up in the mucus, they can cause it to have a yellowish hue," says Dr. Kreel.
It has been shown that a yellowish or greenish sputum colour is often related to the bacterial load of patients suffering from COPD exacerbation [16], [17] or patients hospitalized due to respiratory conditions [18].

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.
Mucus that's green-tinged or yellow can mean that your sinuses have been exposed to an irritant, often an infection. One form your mucus can take is a thick, rubbery, solid consistency. This can be a sign of anything from dry air in your home to a bacterial infection.
Common conditions that cause phlegm to turn yellow include pneumonia, bronchitis, and sinusitis. A person should contact their doctor if they have been producing yellow phlegm for more than a few days.
Green or yellow “sputum,” as clinicians call it, more often than not reflects a bacterial infection, whereas clear, white or rust colored phlegm most likely does not, according to the new study. The results could help doctors determine whether or not a patient would benefit from antibiotics.
Blowing the nose regularly prevents mucus building up and running down from the nostrils towards the upper lip, the all-too-familiar runny nose. Later in colds and with sinusitis, nasal mucus can become thick, sticky and harder to clear.
Chronic sinusitis is most likely if you have two or more of the following symptoms: Nasal congestion or stuffy nose. Mucus and pus-like discharge (yellow fluid draining out of your nose) Postnasal drip (mucus dripping at the back of your throat)
Common symptoms of pneumonia include: a cough – which may be dry, or produce thick yellow, green, brown or blood-stained mucus (phlegm)
However, if you have other respiratory illnesses such as bronchitis or pneumonia with COVID-19, you may have a wet cough that contains mucus. 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.
