Does Pneumonia Berge Is Caused
There are hundreds of types of pneumonia, and most have an origin in an overreaction of your natural defenses that causes infections in the lungs. By rapidly accumulating their white blood cells, white blood cells destroy the invading organisms. You breathe through the tubes that carry air , which are filled with bacteria and fungi.
World Pneumonia Day: Know The Difference Between Viral And Bacterial Pneumonia
- World Pneumonia Day: While bacterial pneumonia is predominantly localized to an area of the lung, viral pneumonia is randomly distributed in all areas of both lungs.
World Pneumonia Day: Pneumonia is a form of acute respiratory infection that affects the lungs. It is most commonly caused by virus or bacteria. Any infection causing an inflammatory response in the lung is referred to as pneumonia. Though the majority of pneumonia is caused by bacterial infections, viral infections like influenza or Covid 19 virus can also affect the lungs and can cause serious inflammatory damage to them.
In Covid times rise in atypical bacterial infections leading to pneumonia which is also called “Walking Pneumonia” caused by organisms like Mycoplasma, Leptospira, oriented , etc, is also seen which usually causes milder disease and can be effectively treated with antibiotics.
“Viral pneumonia is slightly different from bacterial pneumonia in a clinical presentation like the patient will be having rapid progression of symptoms with high-grade fever and severe breathlessness and cough dragging the patient to the hospital,” says Dr. Gopi Krishna Yedlapati, Consultant Interventional Pulmonologist, Yashoda Hospitals Hyderabad.

Is Pneumonia Primarily A Result N Cause Of Pneumonia
There can be many causes of pneumonia, including viruses, bacteria, and fungi. A number of strains of influenza, respiratory syncytial virus , and SARS-CoV-2 are likely to result in viral pneumonia in the United States. It is common for patients to develop bacterial pneumonia due to a strain of Pneumococcus pneumoniae.
Difference Between Viral And Bacterial Pneumonia
Viral vs Bacterial Pneumonia
Pneumonia is an acute respiratory illness associated with recently developed radiological pulmonary shadowing, which may be segmental, lobar, or multilobar. It can occur both as a primary disease or, more commonly, as a complication that affects many seriously ill hospitalized patients. It can be resulted from different pathogenic organisms including bacteria, viruses, fungi etc.
Since all pneumonias share common characteristics, this article points out some of the differences between bacterial pneumonia and viral pneumonia with regard to their prevalence, pathogenic organisms, clinical symptoms and signs, investigations, complications and the management.
It usually causes acute air space pneumonia which results from infection by bacteria that multiply extracellularly in the alveoli. The commonest pathogen is streptococcus pneumoniae which accounts for 60% 70% of the cases while the other bacteria includes legionella pneumophilia , mycoplasma , staphylococcus aureus , etc.
The clinical symptoms and signs vary depending on the organism. For example, streptococcus pneumoniae shows rapid onset symptoms and produces rusty colour sputum while mycoplasma pneumonia has much more complications than the above. Rare complications of mycoplasma pneumoniae include haemolytic anaemia, erythema nodosum, myocarditis, pericarditis, meningoenchephalitis etc.
Bacterial pneumonias are more common than viral pneumonias.

Both Bacteria And Viruses Can Cause Pneumonia But One Is Much Worse For The Heart
11 November 18
CHICAGO Pneumonia caused by bacterial infections poses a much greater threat to the heart than pneumonia caused by viral infections, a new study suggests.
Patients in the study who were diagnosed with bacterial pneumonia had a higher risk of heart attack, stroke or death, compared with patients diagnosed with viral pneumonia, the researchers found.
The findings were presented here today at the American Heart Association’s Scientific Sessions annual meeting. The study has not yet been published in a peer-reviewed journal.
Both bacteria and viruses can cause pneumonia, an infection characterized by inflammation in the air sacs of the lungs.
In the study, the researchers looked at data from 2007 to 2014 on around 4,800 patients at a Utah hospital who had been diagnosed with pneumonia and hospitalized. Around 80 percent of the patients had been diagnosed with bacterial pneumonia. The researchers then looked at data on those patients for the 90 days following their diagnosis, noting which patients experienced heart attack, stroke, heart failure or death.
The researchers found that 34 percent of the patients with bacterial pneumonia had a major heart complication within that 90-day window, compared with 26 percent of the patients diagnosed with viral pneumonia.
How Is Pneumonia Treated
Treatment depends on the type of pneumonia you have. Most of the time, pneumonia is treated at home, but severe cases may be treated in the hospital. Antibiotics are used for bacterial pneumonia. Antibiotics may also speed recovery from mycoplasma pneumonia and some special cases. Most viral pneumonias dont have specific treatment. They usually get better on their own.
Other treatment may include eating well, increasing fluid intake, getting rest, oxygen therapy, pain medicine, fever control, and maybe cough-relief medicine if cough is severe.

Besides Vaccination What Else Can I Do To Prevent Bacterial And Viral Pneumonia
Receiving all recommended vaccinations is one of the best ways to prevent pneumonia. Additionally, there are several other ways to prevent pneumonia, including:
- Quitting smoking, and avoiding secondhand smoke. Smoking damages your lungs.
- Washing your hands before eating, before handling food, after using the restroom, and after being outside. If soap is not available, use an alcohol-based hand sanitizer.
- Avoiding being around people who are sick. Ask them to visit when they are feeling better.
- Not touching or sharing objects that are shared with others. Germs can be transferred from object to you if you touch your nose or mouth without washing or sanitizing your hands first.
- Eating a healthy diet, exercise, and get enough rest. Healthy habits keep your immune system strong.
- Getting treated for any other infections or health conditions you may have. These conditions could weaken your immune system, which could increase your chance of infections.
- Avoiding excessive consumption of alcohol.
Why Is Pneumonia Dangerous What Are The Possible Complications Of Leaving This Condition Untreated
Pneumonia can usually be treated successfully without leading to complications. However, complications like the ones listed below can develop in some patients, especially those in high-risk groups.
Fluid or pus could get accumulated between the covering of the lungs and the inner lining of the chest wall this is called a pleural effusion . A chest tube may be needed to drain the fluid/pus.
Pus might collect in the lung area infected with pneumonia . Rarely this may require surgery.
Bacteria can spread to the bloodstream and other organs. This is a serious complication since the infection can cause the blood pressure to be dangerously low.
Although most people recover from pneumonia, it can be fatal in some cases. Approximately 5 to 10 percent of patients admitted to a general medical ward, and almost 30 percent of patients with severe infection admitted to an intensive care unit can die.

Additionally, what are the 4 stages of pneumonia?
Pneumonia has four stages, namely consolidation, red hepatization, grey hepatization and resolution.
- Consolidation. Occurs in the first 24 hours. Cellular exudates containing neutrophils, lymphocytes and fibrin replaces the alveolar air.
- Red Hepatization. Occurs in the 2-3 days after consolidation.

How Long Does Viral Pneumonia Last
Your recovery time depends on how healthy you were before you were diagnosed with viral pneumonia. A young, healthy adult will usually recover faster than other age groups. Most people recover in a week or two. Adults or seniors may take several weeks before they fully recover.
The best way to prevent pneumonia is to practice good hygiene, get the seasonal flu shot every year, and try to avoid those around you who are sick with a cold or the flu.
What Are The Signs And Symptoms Of Bacterial Versus Viral Pneumonia In Adults
Symptoms of pneumonia can range from mild sometimes called walking pneumonia to severe. How serious your case of pneumonia depends on the particular germ causing pneumonia, your overall health, and your age.
Bacterial pneumonia: Symptoms of bacterial pneumonia can develop gradually or suddenly. Symptoms include:
- High fever
Additional symptoms appearing about a day later include:
- Higher fever
- Shortness of breath

What’s The Connection Between Coronavirus And Pneumonia
Infection with SARS-CoV-2 begins when respiratory droplets containing the virus enter your body through your upper respiratory tract. As the virus multiplies, the infection can progress to your lungs and can further spread the infection. During this time, the chances of developing pneumonia become high and thus can lead to COVID-19 pneumonia.
Now, the question comes – how does this actually happen? Well, the oxygen you breathe into your lungs crosses into your bloodstream inside the alveoli, the small air sacs which are present in your lungs. However, infection with SARS-CoV-2 can damage the alveoli and surrounding tissues.
Further, as your immune system fights the virus, inflammation can cause fluid and dead cells to build up in your lungs. These factors interfere with the transfer of oxygen, leading to symptoms like severe coughing and extreme shortness of breath.
According to the studies, people infected with COVID-19 pneumonia can also go on to develop other illnesses such as acute respiratory distress syndrome . Acute respiratory distress syndrome is a progressive type of respiratory failure that occurs when the air sacs in the lungs fill up with fluid. This can make it the person hard to breathe and thus leads to breathlessness.
At times, such patients are also put under ventilation for life support.
Who Is Most At Risk For Getting Pneumonia
People who have an increased risk of pneumonia include:
- People over the age of 65 and infants under age 2. The weakening immune system of older people makes them less able to fight off illnesses. Similarly, the immune system of infants is still developing and not at full-strength, making them more susceptible to infection.
- People with a health-caused weakened immune system. Examples include:
- People who are receiving chemotherapy
- Transplanted organ recipients
- People who have HIV/AIDS
- People with autoimmune disease and who are taking medications that suppress the immune system.

Pneumonia Virus Of Mice
Pneumonia virus of mice was highly prevalent in mouse colonies before routine surveillance programs were initiated. This virus or related viruses also infect rats, cotton rats , hamsters , gerbils , guinea pigs , and dogs. The infection is often subclinical and typically detected by sero-surveillance, generally by ELISA. Pneumonia virus of mice received its name when pneumonia developed in suckling mice following experimental serial passage, but natural disease occurs only in immunodeficient mice. Seropositive immunocompetent mice recover from infection without evidence of a carrier state, but the virus is a clinically important infection in immunodeficient mice, such as nude and severe combined immunodeficient mice. Like Sendai virus, pneumonia virus of mice is noncytolytic and infects respiratory epithelium and type II pneumocytes. However, pneumonia virus of mice virus tends to infect individual cells, rather than the entire respiratory epithelial population, so cellular immune responses do not result in recognizable necrotizing lesions that are typical of Sendai virus infection. T-cell-deficient mice develop progressive interstitial pneumonia that is difficult to differentiate from Sendai virus pneumonia in immunodeficient mice. Pneumonia virus of mice infection of marginally immune deficient mice may exacerbate pneumonias caused by either Pneumocystis spp. or bacterial infections.
How Are They Treated
Many cases of walking pneumonia dont require treatment. To help your body heal, its best to rest as much as possible and stay hydrated. If you have a fever, you can take acetaminophen or ibuprofen. You can also ask your doctor about taking an antibiotic.
Pneumonia and more serious cases of walking pneumonia may need additional treatment, such as:
- oxygen to assist with breathing
- intravenous fluids
- breathing treatments to help loosen the mucus in your airways
- corticosteroids to reduce inflammation
THE MAIN DIFFERENCE:
Walking pneumonia often doesnt require treatment, though some cases may need antibiotics. Pneumonia may require additional treatment to improve breathing and reduce inflammation in your airways.

Causal Model : The Fork
In our second model , we again assume that viral severity drives bacterial infection, but we assign all mortality to be a direct outcome of V, with no effect of B. In other words, V is the common cause of B and D. As in the pipe model, the virus promotes bacterial infection through some mechanism , but it is the virus alone that drives mortality bacterial infection is simply a signpost of virally mediated death. In our simulation , we again see the same qualitative pattern of bacterial infections enriched among fatal cases despite the fact that B is not a direct cause of death.
Viral And Bacterial Pneumonia Symptoms Are Quite Similar
If you have pneumoniaeither bacterial or viralyoull typically have a cough that brings up sputum, fever, shortness of breath, and chest pain when you cough or take a deep breath, says Kimberly Brown, MD, MPH, an emergency medicine doctor in Memphis, Tennessee.
It can be difficult to tell by symptoms alone whether you have viral or bacterial pneumonia, says Dr. Brown.
But there is one potential tip-off that its bacterial, and not viral. Generally, bacterial pneumonia causes the more severe symptoms, Turner says.
Don’t Miss: Does The Flu Cause Pneumonia
Causal Model : The Multi
Finally, we consider the case where V causes mortality directly and also indirectly via B . The virus may kill without bacterial infection and also potentiate a bacterial infection that then kills. In this model, we yet again see more bacterial infection in non-survivors. The multi-path causal model introduces the potential for multiple causal pathways connecting viral infection to death and so raises the more quantitative question of their relative importance.
To summarize, our simple epidemiological causal analysis demonstrates that we cannot simply infer from the suggestive pattern of data in Figure 1 that bacterial infections play a causal role in COVID-19 deaths as alternate causal pathways can account for the same pattern in the data . Under all four causal structures, individuals with bacterial infection had a higher mortality rate than those without. In the pipe causal structure , bacterial infection is the sole direct cause of death, and so consequently in our simulation of this model all individuals who died had a bacterial infection. We can therefore rule this structure out, as COVID-19 patients frequently die of viral complications without reported secondary bacterial infection. In contrast, the remaining three causal structures all generate patterns of data that reflect real-world observations , while capturing very different biological assumptions on the relationships between viral infection, secondary bacterial infections, and death.
How The Virus Or The Bacterial Affects The Lungs
Viruses in case of COVID-19 affect both sides of the Pneumon by releasing a more uniform kind of inflammatory response that results in an elevated cellular mucus and debris where earlier open pneumon pockets were present.
Bacteria affects or attacks only one part or lobe of the pneumon resulting in a specific region of inflammation to take over the cellular particles that were filled with air.

How Soon After Treatment For Pneumonia Will I Begin To Feel Better
How soon you will feel better depends on several factors, including:
- Your age
- The cause of your pneumonia
- The severity of your pneumonia
- If you have other at-risk conditions
If you are generally healthy, most symptoms of bacterial pneumonia usually begin to improve within 24 to 48 hours after starting treatment. Symptoms of viral pneumonia usually begin to improve within a few days after starting treatment. A cough can last for several weeks. Most people report being tired for about a month after contracting pneumonia.
