Let's learn more about COVID Pneumonia, the pneumonia that comes with COVID.

Are you also worried that something will happen to your lungs when you get COVID? Sometimes when you get COVID-19 (`COVID-19`) it just comes on like a fever or a cold and gets better in a few days, but for some people it can be a little more severe. That's when this condition called ``COVID pneumonia'' or ``COVID Pneumonia'' occurs. Let's talk about this simply, in a way that you can understand, as if you were talking to a close friend.

What is COVID Pneumonia?

Simply put, COVID pneumonia is an infection that occurs inside your lungs. It is caused by the virus called SARS-CoV-2, which causes COVID-19. You can get COVID-19 and develop pneumonia as a complication. This is when your body's immune system fights off the viral infection in your lungs, causing the lungs to swell and fill with fluid. This makes it very difficult to breathe.

You may have heard of something called `(Bilateral interstitial pneumonia)`. Pneumonia associated with Covid-19 often occurs in both lungs at the same time. That's why it's called `(Bilateral)`. The tissue that surrounds the air sacs and blood vessels in the lungs is called `(Interstitial tissue).` In this condition, this tissue in both lungs is damaged. Some people can develop `(long COVID or PASC - post-acute sequelae of SARS CoV-2)` lung problems even after they recover from Covid.

How does COVID-19 affect the lungs?

Covid-19 is a respiratory disease caused by the virus `(SARS-CoV-2)`. This virus enters your respiratory tract directly and damages your lungs. So, as your immune system works to fight this infection, the inflammation that it causes can also damage your lungs. Also, fluid starts to accumulate in the tiny air sacs `(alveoli)` inside the lungs. That's what we call pneumonia.

Can COVID-19 cause pneumonia?

Yes, it is possible. The virus that causes COVID-19 can infect your lungs and cause pneumonia. Sometimes, when your immune system is weakened by COVID, another bacteria can infect your lungs and cause pneumonia. This is called a ``superinfection.`` Also, if you have difficulty breathing due to COVID-19 and are connected to a ``ventilator,`` there is a risk of developing ``ventilator-associated pneumonia.``

Are Covid pneumonia and Covid-19 two diseases?

No, they are not two diseases. To be precise, these are two different cases of the same disease. Covid-19 is a respiratory disease caused by the `(SARS-CoV-2)` virus. Covid pneumonia is a complication of Covid-19, a condition in which the lungs become swollen and filled with fluid, making it difficult to breathe.

What is the difference between Covid pneumonia and other types of pneumonia?

Any pneumonia causes the lungs to swell and fill with fluid. However, research has found that the way the virus that causes Covid pneumonia, SARS-CoV-2, spreads through the lungs is a little different than pneumonia caused by other viruses and bacteria.

Think of it this way. Usually, another type of pneumonia is something that spreads quickly through the lungs, like a wildfire. The symptoms come on suddenly and get worse quickly. But it doesn't last long.

But in Covid pneumonia, the virus seems to enter several places in the lungs at the same time and stay there. Then, using your own immune system, it starts to spread to other parts of the lungs. It's like lighting a lot of small fires in a forest. After a while, the sparks from those fires spread, ignite new places, and gradually spread the damage to the entire area. So Covid pneumonia is likely to last longer and damage more parts of the lungs .

Who is at higher risk of developing Covid pneumonia?

There are some people who are at higher risk of developing severe COVID-19 disease and conditions like COVID pneumonia. If you fall into one of these groups, it's a good idea to be a little more careful, right?

• If you are over 65 years old.
• If pregnant.
• If you are a smoker, or if you have smoked in the past.
• If someone has had an organ or blood stem cell transplant.

Also, if you have any of the following medical conditions, your risk is even higher:

• Blood disorders (e.g. sickle cell disease, thalassemia).
• Cancerous conditions.
• Cerebrovascular disease (e.g. stroke).
• Chronic kidney or liver disease (e.g. hepatitis, cirrhosis, non-alcoholic fatty liver disease (NAFLD)).
• Chronic lung diseases (e.g. asthma, COPD, pulmonary fibrosis, pulmonary hypertension, pulmonary embolism).
• Cystic fibrosis.
• Neurological diseases like dementia and Alzheimer's disease.
• Diabetes (Type 1 or Type 2) `(Diabetes - Type 1 or Type 2)`.
• Birth defects such as cerebral palsy and Down syndrome.
• Heart disease (e.g. heart failure, coronary artery disease, hypertension).
• HIV/AIDS or other diseases that weaken the immune system.
• Mental health problems (e.g. depression, schizophrenia ).
• Obesity.
• Drug use (such as alcohol, opioids, cocaine).
• Tuberculosis.

How many people who get COVID-19 develop pneumonia?

Typically, about 15% of people who get COVID-19 develop severe complications, including COVID-19 pneumonia. That means more than 77 million people worldwide have now experienced severe cases of COVID-19. So this is not something to be taken lightly.

What are the symptoms of Covid pneumonia?

The symptoms of COVID-19 pneumonia can be very similar to those of a normal COVID-19 infection. However, if these symptoms appear new or if existing symptoms become more severe , it may mean that your COVID-19 condition is progressing to pneumonia. If this happens, it is important to seek medical advice immediately.

• Difficulty breathing (dyspnea) or shortness of breath.
• Feeling confused, like losing your mind.
• Feeling extremely tired and exhausted.
• Cough (maybe a cough with mucus).
• Fever.
• Chest pain or tightness.
• Blue discoloration of the lips, skin, or nails (cyanosis).

If any of these symptoms appear new or worsen, it's best to see a doctor immediately. Don't ignore it, especially if it's accompanied by difficulty breathing.

How do I know if my COVID-19 infection is progressing to pneumonia?

The symptoms of both COVID-19 and pneumonia are very similar, so it can sometimes be difficult to diagnose. However, if the COVID-19 infection progresses to pneumonia, the main and most obvious symptom is increasing difficulty breathing. If you feel like you are having trouble breathing, or if you are feeling suffocated, go to the nearest hospital immediately.

Is Covid pneumonia contagious?

The virus that causes COVID-19 is contagious. When you are infected, you can spread the virus to others not only when you cough, sneeze, talk, but also when you breathe. Pneumonia is a condition that occurs in your lungs when you have COVID-19. You can spread COVID-19 to someone else from someone who has COVID pneumonia. However, it is not certain that that person will also develop pneumonia.

However, sometimes you can develop pneumonia due to a bacterial infection along with Covid-19, as we have said before, a ``superinfection.'' That bacterial infection can be contagious. It can also cause pneumonia in someone else.

How to diagnose Covid pneumonia? (Diagnosis)

To find out for sure if you have COVID pneumonia, a doctor will ask you about your symptoms and do a physical exam. They will listen to your lungs with a stethoscope, check your blood pressure, temperature, and oxygen levels (pulse oximetry). Often, a nasal swab may also be taken to confirm whether you have COVID-19 or another viral infection.

In addition, several other tests can be performed:

• Imaging of the lungs:A chest X-ray or CT scan is done to check for lung infections.
• Blood tests: A sample of your blood will be taken to help determine whether your pneumonia is caused by COVID-19 or a bacteria.
• Sputum test: You are asked to cough, and a sample of the sputum is taken and sent to a laboratory to see if there is an infection and what is causing it.
• Pleural fluid culture: Sometimes, a small amount of fluid around the lungs is taken using a thin needle and tested.
• Arterial blood gas test: A blood sample is taken from an artery in your wrist, arm, or groin to check the level of oxygen in your blood. This can give an idea of ​​how well your lungs are working.
• Bronchoscopy: In an emergency, a thin, lighted tube (bronchoscope) can be passed into the lungs to look inside and take tissue or fluid samples.

How is Covid pneumonia treated?

If you are diagnosed with COVID pneumonia, you will likely be hospitalized. There, you may receive treatment such as:

• Antiviral medications: There are some antiviral medications, such as Remdesivir or Paxlovid™, that directly attack the virus that causes COVID-19 and help control the infection.
• Antibiotics: These are given for pneumonia caused by bacteria. These medications are given if it is confirmed that you have a bacterial infection along with COVID pneumonia. Sometimes, they may also be given as a precautionary measure if there is a suspicion that you may have a bacterial infection.
• Supplemental oxygen: If your lungs are working but your body is not getting enough oxygen, supplemental oxygen is given through a tube placed in your nose or a mask placed on your face.
• IV fluids: Things like IV saline are given to stop the body from becoming dehydrated.
• Removing fluid from the lungs: Fluid that has accumulated in the lungs can be removed either by inserting a catheter or through surgery.
• Corticosteroids: Steroid-type medications, such as Dexamethasone, are used to reduce swelling in the lungs.
• Monoclonal antibodies: Treatments like Tocilizumab can help reduce or prevent inflammation.
• Mechanical ventilation: If you are unable to breathe properly on your own, you will be connected to a ventilator. In this, a tube is placed down your throat into your windpipe, and a machine is used to breathe for you. During this time, you will be put to sleep.
• Extracorporeal membrane oxygenation (ECMO): If your lungs or heart are not working properly, you may be connected to an ECMO machine. This is a life-saving treatment that takes over the work of your heart and lungs.

Remember, your doctor will evaluate each of these treatments and determine what is best for your condition. Therefore, it is important to follow their instructions exactly.

How to prevent Covid pneumonia?

The best way to prevent COVID pneumonia is to reduce your risk of developing COVID-19 and other conditions that can damage your lungs. You can do these things:

• Getting the Covid-19 vaccine.
• Get vaccinated against pneumococcal disease, which can cause bacterial pneumonia.
• Avoid smoking and protect yourself from secondhand smoke.
• Wash your hands thoroughly with soap and water before eating, before preparing food, and after using the toilet. If soap is not available, use an alcohol-based hand sanitizer.
• If you or someone else has COVID-19, avoid close contact and sharing items.
• If you have other health conditions (those that fall into the risk groups we discussed earlier), get them treated properly, as those conditions can make COVID-19 more severe.

How long does it take to recover from Covid pneumonia?

It's impossible to say exactly how long COVID pneumonia will last. It can vary from day to day. Some days you may feel better, but then it can get worse. Typically, a mild case of the illness will take three to six weeks to recover. However, if the condition is severe, it can take months to recover. How quickly you feel better depends on:

• your age.
• The severity of pneumonia.
• Whether you have any other health problems or complications.

If you continue to have health problems after treatment for COVID pneumonia, it is important to see your doctor again for advice.

What are the possible complications of Covid pneumonia?

Covid pneumonia is a complication of Covid-19 infection. There are different levels of how sick you can get from the `(SARS-CoV-2)` virus. Think about it this way:

1. Viral respiratory illness: This is the mildest form of COVID-19 infection. But it can still cause symptoms like fever, sore throat, and difficulty breathing, which can be very serious. Most people can manage their symptoms at home. However, if symptoms become severe, they may need to be hospitalized.

2. COVID pneumonia:This is when the lungs become infected, swollen, and filled with fluid, making it difficult to breathe. If you have COVID pneumonia, you will need to be monitored closely in the hospital and treated for your symptoms. This is usually considered a moderate to severe case of COVID-19.

3. Acute respiratory distress syndrome (ARDS): Acute respiratory distress syndrome (ARDS) is a condition in which the respiratory system fails. This is when your lungs are not working properly, preventing your body from getting enough oxygen. If you get into this critical stage of COVID-19, you may need to be connected to a ventilator to breathe for you.

What is the recovery rate from Covid pneumonia?

In normal times, when hospitals are not overwhelmed by the influx of patients, the recovery rate from COVID pneumonia is about 80%. That means that about 80 out of 100 people recover. However, if a large wave of patients arrives at once and overwhelms hospitals, the number of deaths from COVID pneumonia can double. Therefore, seeking treatment as soon as possible increases your chances of saving your life and recovering quickly.

What can I do to stay well when I have COVID pneumonia?

After you are discharged from the hospital, you can do these things to continue your recovery journey at home:

• Control your symptoms with the medications and other treatments recommended by your doctor.
• Take every prescribed medication and treatment exactly as prescribed, until it is completed on time.
• Get plenty of rest. Don't overwork your body.
• Continue to monitor your symptoms. If you feel unwell at any time, or if you develop new symptoms, call your doctor immediately.

What are the signs that Covid pneumonia is getting better?

As you begin to recover from COVID pneumonia, you should no longer have difficulty breathing. As your condition improves, your doctors will reduce the number of machines you are on to help you breathe and the amount of oxygen you are given.

If you feel like you can do some of your normal activities after you get home, that's also a good sign that you're recovering.

When should I see a doctor?

If you have any symptoms of COVID-19, such as loss of taste or smell, sore throat, fever, cough, or difficulty breathing, get tested for COVID-19. If you are at risk for severe COVID-19, or if you have questions about how to manage your symptoms, contact your doctor.

When should I go to an emergency room?

If you have COVID-19 andIf you develop new symptoms or if an existing symptom gets worse, especially if you have trouble breathing, feel confused, can't seem to stay awake, or if your skin, lips, or fingernails appear to be turning blue, go to an emergency room immediately or call 911.

Some people have very mild symptoms of COVID-19. But others can develop severe conditions like COVID pneumonia. It's important to pay close attention to your symptoms. This is especially important if you're over 65 or have other chronic conditions that can make COVID-19 more severe.

The virus can cause serious damage over time. So, if your symptoms become severe, don't delay in seeing a doctor or going to the hospital. Symptoms like difficulty breathing, difficulty staying awake, confusion, and blue skin, lips, and fingernails are not normal. They need to be treated immediately.

Finally, remember (Take-Home Message)

Covid pneumonia is not something to be trifled with, my friends. It is a serious complication of Covid-19.

• Be aware of the risk factors and symptoms so that you can take action quickly.
• Prevention is the best way. Get vaccinated properly and practice good hygiene.
• If symptoms become severe, especially if you have difficulty breathing, seek medical advice without delay. Prompt treatment can save a life.

Let's all be careful and try to recover from this pandemic as soon as possible. If you have any problems, don't be afraid to talk to a doctor.
