Every year, many people suffer from respiratory illnesses. Some illnesses are mild and some even more severe; they require hospitalization. Flu and pneumonia are two conditions that are often confused with each other. Understanding the difference between the two is necessary for early diagnosis and proper treatment.
Whether you are protecting your health or simply trying to get information about diseases and conditions this guide will help you to understand the key differences between flu and pneumonia.
Understanding the Flu
In medical terminology flu is known as influenza because it is caused by the influenza virus. It is a contagious infection that affects your nose, throat and lungs. It can easily spread from one person to another through their workspaces or communities. People suffer from the flu, especially in the fall and winter due to seasonal changes. The onset of this disease is rapid because the symptoms appear very fast in a person affected by the disease. It is a key indication of the influenza virus that differentiates it from pneumonia.
Recovery from flu depends on the severity of its occurrence and the individual’s health. If an individual maintains good nutrition and diet and stays consistent with their fitness and exercise, they recover fast. Infants, older adults and pregnant women and people with compromised immune systems face a high risk of complications from having the flu.
Understanding Pneumonia
Pneumonia is a condition in which the alveoli, the air sacs present in the lungs get inflamed due to the filling of fluid, like pus, due to any bacteria, virus or fungi. It is more severe than a normal flu. Pneumonia is an infection that affects the lungs deeply, so breathing becomes difficult and symptoms become worse. There are different types of pneumonia. Among them are necrotizing pneumonia, a very dangerous type of pneumonia that involves death of lung tissue, and cavitary pneumonia, a rare but severe form in which lung tissue dies and forms cavities. Pneumonia involving more than one lobe of the lung is called multifocal pneumonia.
Flu Symptoms vs Pneumonia Symptoms
Pneumonia and flu are the two main illnesses that people mistakenly think they have. This usually happens because both diseases share a few symptoms. Fever, coughing, and tiredness could be caused by either illness, but there are differences in how they show up and how severe the sickness is.
Flu Symptoms
Flu attacks with not only high fever but also chills, hotness, body, and muscle pains. Gradually or suddenly, headache, extreme tiredness, sore throat, dry cough, and runny or blocked nose can come up. The onset of flu symptoms is very fast.
Pneumonia Symptoms
Usually, pneumonia symptoms are hard to differentiate from the flu or cold symptoms at first, but they progress and get worse in the end. Among pneumonia, shortness of breath, fever, chills, and a bad cough with thick mucus are the main signs. Moreover, the chest pain caused by pneumonia is aggravated by deep breathing.
Always present are sweating, weakness, tiredness, and, in very bad cases, lips or nails turning blue. Pneumonia goes deeper into the lungs than the flu, hence the latter’s severity with breathing problems is not the same as the former’s.
Pneumonia vs Bronchitis
Pneumonia and bronchitis share the same symptoms of coughing and lung irritation. So these are also often confused with each other. It is important to know that pneumonia is a disease that affects the lung tissues, while bronchitis is a disease that affects the bronchial tubes of the respiratory tract. Mostly, bronchitis does not cause any dyspnea, shortness of breath or any extreme level of reduced oxygen levels but comes with a cough that lasts for weeks. On the other hand, pneumonia, if left untreated, can be deadly. Especially for elderly people and those suffering from any mental health disorder because it weakens their immunity.
Flu and Pneumonia: What are the Causes?
Influenza, commonly known as the flu, is a virus that affects the respiratory tract. Influenza viruses are of three types, influenza virus type A, B and C. Types A and B are serotype viruses that mainly cause the epidemic flu. Influenza type C is a mild form of the virus and is less detected. These viruses are transmitted by coughing, sneezing, and even talking.
One of the most common sources of pneumonia is a bacterium known as Streptococcus pneumoniae. It can also be caused by a virus or fungi. Fungi causing pneumonia are rare but the most dangerous ones.
It is important to mention here that flu is a primary infection followed by a secondary infection, the pneumonia, if it is severe and affects the lungs. Pneumonia can occur after flu. But flu after pneumonia is not common.
Who is More Vulnerable to Flu and Pneumonia?
Flu or pneumonia can occur in any person. But infants, elderly people above 65 years of age, and patients with severe heart or lung diseases are mostly affected. In some cases pregnant women are also at risk of developing flu or pneumonia. People with chronic diseases and conditions such as diabetes or asthma are also more prone to getting an infection quickly. Moreover, poor diet and nutrition, lack of physical fitness and reduced immunity levels also affect the ability of the body to fight against diseases.
How to Diagnose Flu and Pneumonia?
Flu and pneumonia are diagnosed mainly through their symptoms. But there are some special lab tests that help them differentiate from each other. For flu diagnosis, the Rapid Influenza Diagnostic Test is used for confirmation of the disease. And pneumonia is detected by physical examination, chest x-ray and blood and sputum culture. These cultures help to diagnose a specific form of pneumonia.
Treatment of Flu and Pneumonia
Flu is treated mainly at home, not taking any specific medications. Rest, increased fluid intake and some OTC medication are used to treat flu. You can also get some antivirals from the drugstore. A balanced diet, moreover, reduces the recovery period.
Pneumonia requires a proper examination and treatment. Ruling out its underlying cause is important. Figuring out whether it is caused by any bacteria, virus or fungi is important for the specified treatment. After ruling out antibiotics, antivirals or antifungal medications are prescribed. Severe forms of pneumonia do require proper hospitalization.
Recovery Period of Flu and Pneumonia
In minor cases of flu, the majority of people recover within a week after the onset of flu while in severe cases, recovery may take up to fourteen days. Moreover, fatigue may last longer, especially for people with stressful occupations or unstable mental health.
On the other hand, the recovery time of pneumonia depends on its type and severity. Mild pneumonia generally takes one to three weeks, while severe cases last months to a year or even longer.
Recovery from pneumonia is slow because of the healing process of the lungs. The people with pre-existing conditions or those with weakened immune systems will take longer than usual to recover from pneumonia.
Prevention
Flu and pneumonia can be prevented by receiving a flu vaccination every year and by consistent hand sanitization. Good hygiene plays a preventive role in human health. Vaccinations prescribed by a pediatrician can be considered for infants. Regular physical fitness and exercise, along with a good diet, can help keep the body’s immune system strong.
A Visit to the Doctor
If you experience some difficulty in breathing, have chest pain, or have a very high fever that lasts more than three days, you should visit your doctor immediately. You should consider visiting your doctor if you experience any disorientation, severe fatigue, or if the lips and nails is turning blue.
Conclusion
Differentiating flu and pneumonia helps you to early diagnose and early treat the conditions. Flu and pneumonia are both respiratory diseases, in which pneumonia is more of a concern and requires immediate medical treatment especially for people more prone to it. The best you can do for your family and yourself is to stay healthy by being proactive and educated about health. Getting your vaccinations and having a yearly checkup will help you to reduce the chances of flu or pneumonia development.
