A virus, bacteria, fungus, or parasitic infection can cause a lung infection. Sometimes, the lung infection can affect the smaller air sacs causing pneumonia, or the larger airways causing bronchitis.
Pneumonia is a common type of lung infection. It is most commonly caused due to contagious bacteria or a virus.
A person can suffer from any type of lung infection when he or she breathes in the bacteria or virus when an infected person nearby coughs or sneezes.
Pneumonia, bronchitis, tuberculosis, and bronchiolitis are the common types of lung infection.
Most commonly, people suffer from pneumonia during winter or spring. It can strike suddenly and resolve on its own within a few days. People will experience the symptoms according to age, the cause, and the severity of the infection. In some cases, underlying health conditions may also cause such symptoms:
As said, there are four types of lung infections such as bronchiolitis, bronchitis, tuberculosis, and pneumonia. Typically, they are caused due to bacteria or a virus.

Bronchitis is caused due to most common microorganisms like:
Pneumonia is caused by the most common microorganisms like:

This helps your doctor to diagnose any type of lung infection and determine the exact location of the infection.
It is a procedure where the doctor draws a sample of fluid from your lungs to do an intense cough analysis to find the infection and its causes.
This procedure measures the oxygen levels in the blood. Lung infections like pneumonia can prevent your lungs from passing sufficient oxygen into the bloodstream.
Blood tests help to confirm an infection and try to identify the type of microorganism that causes infection. However, the blood test does not always yield microorganism identification.
This test helps determine your lung capacity and what kind of lung impairment you may be suffering. In this test, you blow air into a device called a spirometer. The device checks how much air your lungs can hold and how quickly it can get out of your lungs. This test helps to detect the signs of emphysema and asthma.
In this test, your doctor will collect a sample of mucus through a swab inserted through the nose to analyze and find the virus that causes bronchiolitis.
Doctors may order additional tests if you or the patient is older than 65 years and have any severe health conditions or it’s symptoms.
Bacteria, viruses, fungi, or parasites may give you a lung infection. The common types of lung infection include pneumonia, bronchitis, tuberculosis, and bronchiolitis. If you show the symptoms of any of these conditions, consult with a doctor right away.
