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.
A chest infection is an infection of the lungs or airways. The main types of chest infection are bronchitis and pneumonia. Most bronchitis cases are caused by viruses, whereas most pneumonia cases are due to bacteria. These infections are usually spread when an infected person coughs or sneezes.
Causes. Sinus infections happen when fluid builds up in the air-filled pockets in the face (sinuses). This fluid buildup allows germs to grow. Viruses cause most sinus infections, but bacteria can cause some sinus infections.
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.
The research found that patients producing discoloured phlegm are prescribed antibiotics more frequently than those not producing phlegm unlike those producing clear/white phlegm.
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.
Antibiotics and sinus infections
This may give you the idea that you need antibiotics, but most clear up without them. Antibiotics have no effect on viruses and aren't recommended within the first week of developing a cold. About 70% of sinus infections go away within two weeks without antibiotics.
The most common cause of acute sinusitis is a viral infection associated with the common cold. This condition is also called viral sinusitis. Bacterial sinusitis occurs much less commonly, in only 0.5 to 2 percent of cases, usually as a complication of viral sinusitis.
Even without antibiotics, most people can fight off a bacterial infection, especially if symptoms are mild. About 70 percent of the time, symptoms of acute bacterial sinus infections go away within two weeks without antibiotics.
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.
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.
Typically, antibiotics are needed when: Sinus infection symptoms last over a week. Symptoms worsen after starting to get better. Sinusitis symptoms are severe (high fever, skin infection or rash, extreme pain or tenderness around the eyes or nose)
Bacterial infections may be the result of "secondary infection" (meaning that the virus initiated the process but a bacteria followed) when the: Symptoms persist longer than the expected 10-14 days a virus tends to last. Fever is higher than one might typically expect from a virus.
The radiograph still remains the reference standard for a medical diagnosis of pneumonia, and also helps to differentiate between bacterial and viral pneumonia. However, a combination of clinical symptoms, exam findings, and imaging is the best way to uncover the most likely culprit.
Many symptoms are the same, including headache or facial pain, runny nose and nasal congestion. Unlike a cold, a sinus infection symptoms may be caused by bacterial infections. It often requires treatment with antibiotics (drugs that kill the germs causing the infection).
Left untreated, a sinus infection has the potential to spread to your meninges (the protective coverings around your brain and spinal cord), causing them to become inflamed — a condition called meningitis. Meningitis gives rise to the following signs and symptoms: Sudden, high-grade fever. Neck stiffness.
Sinus infections can be viral or bacterial. “Either way, it's best to stay home,” Wigmore says. Viral sinus infections are often contagious. If you have had symptoms longer than one week, or if you have severe facial pain, teeth/jaw pain, or fever, you may have a bacterial infection and should consult your doctor.
You doctor may recommend antibiotics if: You have symptoms of a bacterial infection and you have not gotten better after 10 days, even with home treatment. Your symptoms are severe, or you have other problems, such as pus forming in your sinus cavities. You have had sinusitis for 12 weeks or longer (chronic sinusitis).
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.
Yellow mucus can indicate a bacterial infection in the nasal passages. This type of infection often requires antibiotics to clear up. If the yellow color is accompanied by thick and discolored nasal discharge, it may be a sign of a sinus infection.
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.
