What is a lung infection?
A lung infection can be caused by viruses, bacteria, or even fungi. One of the most common types of lung infections is pneumonia. Pneumonia, which affects the lung's smaller air sacs, is most commonly caused by:
- Contagious bacteria
- Viruses and
- Fungi

Get A Second OpinionHow do lung infections occur
Bronchitis occurs when the large bronchial tubes that carry air to and from your lungs become infected. Bronchitis is more likely to be caused by a virus rather than a bacterial infection.
Viruses can also infiltrate the lungs or the airways leading to the lungs. Bronchiolitis is the medical term for this condition. Infants are the most commonly affected by viral bronchiolitis.
Symptoms of lung infections
A lung infection can cause mild to severe symptoms. These are determined by several factors, including age and general health, as well as whether the infection is caused by a virus, bacteria, or fungus.
- Strong chest pains
- High fever
- A cough that produces a lot of mucus
- Muscle aches
- A stuffy nose
- Breathing difficulty
- Tiredness
- Sneezing
- The appearance of bluish skin or lips
- Rattling or crackling sounds in the lungs
The following are symptoms of a lung infection:
- Strong chest pains
- High fever
- A cough that produces a lot of mucus
- Muscle aches
- A stuffy nose
- Breathing difficulty
- Tiredness
- Sneezing
- The appearance of bluish skin or lips
- Rattling or crackling sounds in the lungs
Strong chest pains:
The pain in the chest caused by a lung infection is frequently described as sharp or stabbing. When coughing or breathing deeply, chest pain tends to worsen. Sharp pains can sometimes be felt in your mid to upper back.
High fever:
A fever develops as your body attempts to combat the infection. The average body temperature is around 98.6°F (37°C). If you have a bacterial lung infection, your fever can reach dangerous levels of 105°F (40.5°C). Any high fever above 102°F (38.9°C) frequently causes a slew of other symptoms, including:
- Sweating
- Muscle aches
- Dehydration
- Headache
- Weakness
A cough that produces a lot of mucus:
Coughing aids in the removal of mucus produced by the airway and pulmonary inflammation. This mucus may contain blood as well. When you have bronchitis or pneumonia, you may have a cough that produces thick mucus with a distinct color, such as:
- Clear
- White
- Green
- Yellowish-grey
Muscle aches:
When you have a lung infection, your muscles and back may ache. This is known as myalgia. When you have an infection, you may experience muscle inflammation, which can lead to body aches.
A stuffy nose:
A runny nose and other flu-like symptoms, such as sneezing, are frequently associated with a lung infection such as bronchitis.
Breathing difficulty:
Shortness of breath indicates that breathing is difficult or that you are unable to inhale fully. If you're having trouble breathing, you should see a doctor right away.
Tiredness:
As your body fights off an infection, you will typically feel sluggish and tired. Rest is essential during this time.
Sneezing:
When you exhale, you may hear wheezing, which is a high-pitched whistling sound. This is caused by clogged airways or inflammation.
The appearance of bluish skin or lips:
Due to a lack of oxygen, your lips or nails may begin to turn a slightly blue color.
Rattling or crackling sounds in the lungs:
A crackling sound in the base of the lungs, also known as bibasilar crackles, is one of the telltale signs of a lung infection. A stethoscope is a tool that a doctor can use to hear these sounds.
What are the causes of lung infections?
Bacteria or viruses are the cause of lung infections. Lung infections are classified into three types:
- Bronchitis
- Pneumonia, and
- Bronchiolitis
The most common microorganisms that cause bronchitis are:
- Viruses like influenza and respiratory syncytial virus (RSV).
- Mycoplasma pneumoniae, Chlamydia pneumoniae, and Bordetella pertussis are examples of bacteria.
The following are the most common microorganisms that cause pneumonia:
- Streptococcus pneumoniae (the most common), Haemophilus influenzae, and Mycoplasma pneumoniae are examples of bacteria.
- Viruses like the influenza virus and RSV.
Fungi such as Pneumocystis jirovecii, Aspergillus, or Histoplasma capsulatum can cause lung infections in rare cases. Fungal lung infection is more common in immunocompromised people, either due to cancer or HIV or because they are taking immunosuppressive medications.
Treatment for lung infections
Antibiotics are usually required to treat a bacterial infection. An antifungal medication, such as ketoconazole or voriconazole, will be required to treat a fungal lung infection.
Antibiotics do not treat viral infections. Usually, you'll have to wait for your body to fight the infection on its own.
Home remedies for lung infections
The following home care remedies can help your body fight off the infection and make you more comfortable:
- To reduce your fever, take acetaminophen or ibuprofen.
- Drink plenty of water
- Try a cup of hot tea with honey or ginger
- Gargle with saltwater
- Rest as much as you can
- To add moisture to the air, use a humidifier
- Take any prescribed antibiotics until they are finished
Preventions of lung infection:
Although not all lung infections can be avoided, you can reduce your risk by following these guidelines:
- Wash your hands frequently
- Do not touch your mouth and face with your hands
- Avoid sharing utensils, food, or beverages with others
- Avoid congested areas where a virus can easily spread
- Don't use tobacco
- To avoid influenza infection, get a flu shot every year
For those at higher risk, one of two vaccines is the most effective way to prevent bacterial pneumonia caused by the most common strains of bacteria:
- Pneumococcal conjugate vaccine PCV13
- Pneumococcal polysaccharide vaccine PPSV23
These vaccines are advised for:
- Newborns
- Adults in their golden years
- Those who smoke
Conclusion:
A lung infection has symptoms similar to the common cold or flu, but it can be more severe and lasts longer.
Typically, your immune system will be able to clear a viral lung infection over time. Bacterial lung infections are treated with antibiotics.
Consult your doctor right away if you have any of the following symptoms:
- Breathing difficulties
- Bluish tint to your lips or fingertips
- Excruciating chest pain
- A high temperature
If you are over the age of 65, have a child under the age of two, or have a chronic health condition or a compromised immune system, you should seek medical attention right away if you have any symptoms of a lung infection.

The following are some common symptoms of a lung infection:
Pneumonia is a lung infection that can cause severe or life-threatening illness, as well as death. If you or a loved one is experiencing symptoms of pneumonia, it is critical to seek medical attention, especially if you have certain risk factors.
When a dangerous microbe, such as a bacterium or a virus, enters the lungs and causes damage, this is referred to as a lung infection. A lung infection can range in severity from mild to life-threatening. Although the majority of lung infections are treatable and most people recover, they are also extremely dangerous.
In patients with acute bacterial rhinosinusitis, amoxicillin is the preferred treatment. In patients with acute, uncomplicated bacterial rhinosinusitis, short-course antibiotic therapy (median of five days) is as effective as longer-course treatment (median of ten days).
