The viruses that affect the lungs are Rhinovirus, Respiratory Syncytial Virus, Parvovirus B19, Parainfluenza, Influenza, Coronaviruses and Adenovirus.
The bacteria that causes lung infections are Mycobacterium tuberculosis, Staphylococcus aureus, Haemophilus species and Streptococcus pneumoniae.
A lung infection is called pneumonia.
Pneumonia is a lung infection that can be caused by bacteria, viruses, or fungi.
The infection with pneumonia causes the lungs' air sacs (alveoli) to become inflamed and fill up with fluid or pus which can make it hard for the oxygen you breathe in to get into your bloodstream.
The 4 stages of pneumonia symptoms are early congestion, red hepatization, gray hepatization and resolution.
Pneumonia is sometimes caused by a virus but pneumonia can also be caused by bacteria, fungi or other infections.
Viruses, bacteria, and fungi can all cause pneumonia. In the United States, common causes of viral pneumonia are influenza, respiratory syncytial virus (RSV), and SARS-CoV-2 (the virus that causes COVID-19).
A common cause of bacterial pneumonia is Streptococcus pneumoniae (pneumococcus).
The danger signs of pneumonia are.
Abnormal body temperature, such as fever and chills or a lower-than-normal body temperature in older adults or people with weak immune systems.
Shortness of breath or difficulty breathing.
The signs of silent pneumonia are.
Sore throat (pharyngitis)
Feeling tired (fatigue)
Chest pain.
Mild chills.
Low-grade fever.
Persistent cough that can be dry or produce mucus.
Sneezing.
Headache.
The 4 stages of pneumonia are congestion, red hepatization, gray hepatization and resolution.
During the congestion phase, the lungs become very heavy and congested due to infectious fluid that has accumulated in the air sacs.
The early signs of pneumonia are.
Cough, which may produce greenish, yellow or even bloody mucus.
Fever, sweating and shaking chills.
Shortness of breath.
Rapid, shallow breathing.
Sharp or stabbing chest pain that gets worse when you breathe deeply or cough.
Loss of appetite, low energy, and fatigue.
Not all cases of pneumonia warrant a trip to the ER.
That is unless the pneumonia gets worse or you're not getting better.
Pneumonia can be life-threatening if left untreated, especially for certain at-risk people.
You should call your doctor if you have a cough that won't go away, shortness of breath, chest pain, or a fever.
You should also call your doctor if you suddenly begin to feel worse after having a cold or the flu.
