Coughs, stuffy noses, fevers, and a slew of other viruses are on their way when the temperature cools. Influenza (flu) and pneumonia are the two most debilitating diseases that occur at this time of the year. Both the flu and pneumonia are severe diseases, and the flu may lead to pneumonia.
Flu vs Pneumonia
The main difference between flu and pneumonia is that flu usually occurs without warning, while pneumonia takes longer to develop and may be a consequence of flu. A viral infection causes the flu, while pneumonia may be caused by either a bacterial or viral illness. Pneumonia is a lung infection that causes more respiratory symptoms, while the flu causes muscle aches and pains as well as tiredness.
Flu (influenza) is a highly contagious viral infection and one of the most serious diseases in winter. Influenza is readily transmitted from person to person, typically via coughing or sneezing. Cough, cold, and fever are all symptoms of the flu. Pneumonia occurs when the congestion from these diseases spreads to the lungs.
Pneumonia is an illness or inflammation of the lungs that may be fatal. Pus and other fluids can block the air sacs and prevent oxygen from entering the circulatory system. The body’s cells cannot function correctly if there is insufficient oxygen in the blood, which may lead to death.
Comparison Table Between Flu and Pneumonia
| Parameters of Comparison | Flu | Pneumonia |
| Caused | Caused by Influenza virus. | It settles in the lungs where germs, bacteria, and the virus can cause inflammation. |
| Serious | More serious than the common cold. | Most serious should be treated |
| Effects | Nose, throat, and lungs. | Lungs. |
| Soreness and Pain | Sore muscles in your legs, arms, body. | Pain in the chest. |
| Symptoms | Nausea and headache, loss of appetite, high fever, chills, sweat. | Coughing with mucus, disorientation, extreme fatigue. |
What is Flu?
Although the typical cold is usually not a big problem (adults may catch two to three colds a year, while children may catch eight), the flu or influenza is similar to colds in many ways, but it is much more serious. Both are viral respiratory diseases, but although there are more than 200 viruses that can cause colds, there are far fewer influenza viruses.
On the other hand, these influenza viruses are constantly evolving and adapting, which is why it feels different every time they are infected, and just because you’ve had it once doesn’t guarantee your body will identify it and deal with it more quickly the next time. The flu is most infectious in the first three to four days after symptoms appear, although it may spread from one day before symptoms appear to up to a week after you get ill.
While some cold and flu symptoms are similar, such as a stuffy nose, cough, headaches, muscular pains, and tiredness, flu symptoms will be more severe. Also suffer fever, nausea, chills, and sweats, and a lack of appetite. The symptoms will come on fast as well. Antibiotics don’t work on viruses, so most people don’t need to see a doctor for the flu (but extremely young or elderly people, or those with specific medical problems, should).
What is Pneumonia?
Pneumonia, like the flu, is a respiratory illness. Pneumonia, on the other hand, is a more specialized illness that causes inflammation of the air sacs in one or both lungs. In addition, unlike the flu, pneumonia may be caused by a virus, bacteria, or fungus, but bacterial infections are the most frequent cause of pneumonia in adults. Streptococcus pneumonia, the most frequent cause of bacterial pneumonia, has a vaccination, but it’s usually only advised for infants, adults over 65, and people with long-term health problems.
Cough, fever, chills, sweating, headaches, nausea, and exhaustion are all symptoms that are comparable to the flu. It’s also possible that you’re having trouble breathing. You may not realize you need to visit a doctor until you’ve been ill for a long time since the symptoms are so similar. An evaluation, which may include listening to your lungs and perhaps a chest x-ray or blood test, can help a doctor decide whether you have pneumonia.
If the doctor suspects bacterial pneumonia, antibiotics (or antifungals if the infection is caused by a fungus) will most likely be prescribed. Pneumonia is infectious regardless of what caused it. The same precautions that you use to avoid colds and flu washing your hands, wiping germy surfaces, covering your mouth while coughing and sneezing apply to pneumonia as well.
Main Differences Between Flu and Pneumonia
- The influenza virus causes flu, while pneumonia causes inflammation in the lungs due to germs, bacteria, and viruses.
- The flu is a more severe illness than a typical cold. While pneumonia is the most severe illness, it should be treated.
- Flu affects the nose, throat, and lungs, whereas pneumonia affects the lungs severely.
- Flu sore muscles in your legs, arms, body, whereas in pneumonia, pain in the chest severely.
- Symptoms of Flu are Nausea and headache, loss of appetite, high fever, chills, sweat, whereas symptoms of pneumonia are coughing with mucus, disorientation, extreme fatigue.
Conclusion
Influenza is a frequent cause of pneumonia, particularly in young children, the elderly, pregnant women, those with certain chronic health problems, and nursing home residents. The symptoms of flu will appear soon. Stuffy nose, sore throat, fever, and muscle pain all appear out of thin air, and you can determine the exact time they started.
Pneumonia develops gradually, with symptoms becoming more severe over many days. The majority of flu infections do not progress to pneumonia, but those that do are more severe and fatal. There are vaccinations that protect against influenza and certain kinds of pneumonia, but none are 100 percent effective. Because flu strains vary each year, you should receive a flu shot every season to ensure that you are protected against the most recent strains. Pneumonia vaccines are generally only required once, but in rare cases, a booster vaccination may be needed.
