Is Green Mucus from Nose Covid-19 or Allergy?
Medically reviewed by Dr. Mandy Liedeman


Many people may find the appearance of green mucus from the nose unappealing. The presence of such a thing in your pharynx, nasal cavity, and, ultimately, your mouth raises the concern of why it is there in the first place. Phlegm, on the other hand, serves as a lubricant and a barrier.

This mucus can change color due to various conditions that reflect the body’s health status. It may act as a significant health marker, indicating signs of infection, or raise a red flag, signaling you to take corrective action. This may also make you wonder about the COVID-19 phlegm color.

This blog details what different mucus colors indicate, all the facts about your mucus color, and all you should know about COVID-19.

What Does the Color of Your Mucus Mean? 

Surprisingly, the mucus changes color more readily than a person can think. It can change its shade across various colors, with each shade corresponding to some meaning. You might ignore the changes in your everyday routine, but it is better to keep track if you find something unusual apart from your regular, habitual recurrence. Is mucus a sign of COVID-19?

The simple statement that can summarize the answer to this question is that it may or may not be. Here is a guide to the different colors of phlegm and their meanings:

Clear & Watery Mucus

A scratchy throat might indicate that you have COVID-19, not a specified thing that can be stated when you have clear and watery mucus. This type of mucus can be found when there is a seasonal cold. The disease’s initial signs are clear and light mucus whenever you get a common cold or flu. Moreover, It is runny, and controlling it might not be easy. The good news is that clear mucus does not mean you have COVID-19, a slight cold that is viral in the changing seasons. The combined symptoms are watery eyes, an itchy nose, a scratchy throat, and sneezing.  

One of the most common issues that usually results in a runny nose and clear mucus is non-allergic rhinitis. It is a non-allergic condition in which you see this particular type of mucus due to hormonal changes or something that might irritate your nose lining. You can experience this severe effect when you inhale hot spices or often come across highly pungent smells and odors. 

Watery eyes and nose might not be a particular symptom of COVID-19, but the prolonged condition may have dangerous effects. It may be an alarming sign of cerebrospinal fluid rhinorrhea caused by head trauma or injury. Nevertheless, the COVID-19 mucus color is not clear.  

Foamy Green Phlegm 

Well, Is green mucus a sign of COVID? It might be a clear symptom of COVID-19, or it could be any other underlying illness. Are you experiencing green-colored and foamy mucus? Chances are that you are showing signs of a bacterial infection.  

It could also mean that you have an allergic infection, which is why your throat is itchy and you see green phlegm.

Pink Boogers or Red Specks 

There is no need to worry if you have just discovered some pink boogers or red specks. This symptom is not a dangerous sign as long as these boogers and dots are tiny in number. While suffering from an infection, the nasal discharge, mucus, can become red or pinkish because of too much-blowing actions. Since there is constant rubbing and blowing, it is possible that the internal area of the nose gets inflamed and begins to leave red specks on your tissue paper.  

Red specks and pink boogers are often found when someone suffers from an allergy or a viral infection. The use of sprays to treat these ailments of constant blowing of a runny nose can cause the nose tissues to become dry, thus leading to pinkish-red mucus or snot emission when using a tissue. When this happens, the best way to treat it is by using a saline spray or a humidifier to reduce the effects of a dry and red nose.  

Black & Gray Mucus 

Though black and gray mucus types are not commonly seen, they are not to be considered too unusual. This type of mucus can be found in the nostrils when a person spends too much time in an environment full of pollutants harmful to the respiratory system. Examples of such domains include areas where too many factories emit toxic smoke or those that have suffered from fire-related disasters. Such spaces are bound to have pollutants that can damage one’s lungs and breathing system. 

When inhaled, these pollutants can impair the normal functioning of the human respiratory system. Regardless of the color, quantity, or consistency of the mucus emitted, it is always important to note that uncommon symptoms can hint at possible sinus infections. Suppose you continue to suffer from such symptoms related to sinus. In that case, it is recommended to consult a physician and seek medical aid to preserve your health and future well-being.  

Why Does Your Snot Change Its Color? 

You might have noticed that your snot during COVID-19 has some distinctive color that can be shocking at first sight. This colored snot can be traced back to white blood cells containing a greenish-colored enzyme. Upon receiving signals of a virus invasion, these white blood cells rush to the affected area and have such an effect that they can cause your snot to turn the same color, green. If you ask yourself, “Is green mucus a sign of COVID?” you can rest assured. 

Though a common symptom of COVID-19 is green mucus, a green or colored mucus can also indicate regular flu. Green slime can be found under normal conditions when a person suffers from a viral or bacterial infection.  

Green is not the only color you might find in your snot. Studies show that mucus can also contain hints of red or brownish blood red colors that prolonged colds can bring. When your nose gets dry and requires constant rubbing or blowing, the internal area can get irritated and filled with blood. You should not be too worried about small amounts of blood in your snot since this can also happen under chronic conditions. However, if you find large volumes of red-colored snot coming out of your nose, calling a medical expert is probably a good idea.  

Another commonly found color in mucus is brown or orange mucus. Though this weird color may cause panic, dried blood is most likely one possible cause of this symptom. This brown mucus can be brought on if a person breathes in something of a similar color, for instance, dirt, sand, or smoke coming out of a fire or cigarette. In severe cases, brown mucus can denote the possibility of bronchitis, requiring you to seek medical attention immediately since it can affect your normal breathing functions.  

Covid: Why So Much Mucus?

The human body produces about 1 liter to 1.5 liters of mucus daily. The body generates mucus without taking any breaks 24 hours a day. The mucus goes down through the nose without disturbing and making the person uncomfortable. Besides that, there are times when the mucus gets thicker. This does not mean that the body is producing more mucus; instead, the consistency of the mucus has changed. This makes the host feel uncomfortable. In some cases, the body naturally generates mucus of more than the usual amount and reaches the limit. 

An infection such as a bad cold, an allergy, or something the body finds irritating causes a disturbance in the average mucus production. This results in more mucus driven. There are many other reasons for having more mucus than usual. They can be eating something beyond the tolerance level of spice the body can handle. Surprisingly, drinking milk can also be a factor in producing excessive amounts of mucus. 

Misunderstanding About COVID-19 

The biggest misconception about COVID-19 is that most people who have been through COVID-19 once won’t get it again. After that, they forget all about it and stop taking any precautions to avoid being in contact with it again. The biggest mistake is to stop wearing a mask. A person does form a kind of immunity after healing from the covid-19. But the immunity lasts not long; it lasts about three to four months. After this duration, the chances of getting COVID-19 start getting higher and higher. The chances of children getting COVID-19 are higher than adults, mainly because they don’t take precautions too seriously. 

The best option is to get fully vaccinated. To prevent getting COVID-19, take care of hygiene, don’t contact someone sick often, try not to touch your face, and most of all, wear a mask for protection. Practicing these precautions daily will reduce the chances of getting COVID-19 to a bare minimum.

Covid-19 Symptoms 

Based on expert opinions, the most commonly found symptoms of COVID-19 include a sore throat, shortness of breath, tiredness, constant sneezing, and a runny nose.

Additionally, many patients have reported that after contracting the virus, they experienced continuous coughing, itchy throat, and occasional rise in body temperature, often recorded as equal to or greater than 38 degrees centigrade.

Is mucus a sign of COVID-19? Yes, mucus can most probably be found in COVID-19 patients because infections can lead to lung congestion that stays in the system even after the virus has left the body.

How do I tell the difference between COVID-19 and allergies? 

When a virus remains in the system for too long, exposure to harmful variants of the same virus can result in more severe symptoms in patients. Symptoms like blood in cough, pneumonia, bronchitis, or even death can result when the virus gets too powerful to control.  

The symptoms can vary from person to person. Some patients report that while under the influence of this virus, they felt nothing or mild symptoms, including the ones mentioned previously. However, there have also been reports of people suffering that the need to administer proper hospital medicine has become necessary.  

Can you Get Covid Through your Eyes?

Yes, COVID can be transmitted through the eyes like the nose or mouth. Therefore, COVID safety kits have glasses that shield the eye’s path from the entrance of the virus into the body. But the transmission through tears is still uncertain.

How long does Sore throat COVID-19 Last? 

The effects of the virus tend to be more problematic for those in their 40s or 50s because, at this age, the immune system is not as active as it was in the earlier years of one’s life span.

Moreover, people with chronic conditions like diabetes, heart disease, cancer, asthma, etc., can experience worse symptoms because of their previous states.  

Can you have COVID-19 and flu at the same time?

Yes, you can have COVID-19 and flu simultaneously. “Flurona” is the term used to describe the condition in which an individual is having influenza (flu) and COVID-19 simultaneously. However, this term is not commonly used by medical professionals. It can be very challenging to differentiate between the two conditions, although, Flurona is rare.
COVID-19 and influenza are both viral diseases that affect the respiratory system. The symptoms of Flurona include:

  • cough
  • chills
  • fever
  • fatigue
  • shortness of breath
  • body aches
  • sore throat
  • runny or stuffy nose
  • vomiting
  • headache
  • diarrhea
  • loss of taste or smell
Any unusual color of mucus may need an evaluation by a qualified professional. Discuss with a professional now!

When to consult a doctor?

If you are stressed that you have COVID-19 after checking for possible signs, it is wise to ensure you protect the ones around you by taking preventive measures. Additionally, getting the proper tests done to confirm whether you have the virus is always recommended.  

The doctor may suggest some tests, including bronchoscopy or any other relevant test, to help determine the actual cause. 

If you are experiencing green-colored mucus, there is no need to worry; you need to consult a doctor.
