Introduction
Large-area lung infections are pulmonary infectious diseases caused by various pathogens. The most common type is pneumonia, which can be triggered by pathogenic microorganisms such as bacteria, mycoplasma, chlamydia, and viruses, leading to extensive infection in the lungs. In severe cases, it may cause symptoms such as chest tightness, difficulty breathing, and respiratory failure, and could potentially lead to complications including shock and renal insufficiency.
Lung infections involving large areas are pulmonary infectious diseases caused by various pathogens. The most common among these is pneumonia, which can be triggered by pathogenic microorganisms such as bacteria, mycoplasma, chlamydia, and viruses, leading to extensive lung involvement. In severe cases, symptoms such as chest tightness, difficulty breathing, and respiratory failure may occur, potentially resulting in complications including shock and renal insufficiency.
1. Bacterial infection causing pneumonia
The most common clinical cases involve bacterial infections in the lungs caused by Streptococcus, Staphylococcus, Klebsiella pneumoniae, or Haemophilus influenzae. Clinically, it is important to identify the causative pathogen as precisely as possible and select appropriate antibiotics based on its susceptibility. Additionally, adequate nutritional support and symptomatic management should be emphasized.
2. Viral infection causing pneumonia
When the body is invaded by viruses such as adenovirus, coronavirus, influenza virus, or herpes simplex virus, extensive lung infection may also develop. In such cases, antiviral therapy is required; if secondary bacterial infection occurs, antibiotic treatment should be administered concurrently.
3. Fungal infection causing pneumonia
Common causes of fungal lung infections in clinical practice include Candida albicans, Actinomyces, and Aspergillus infections. Prompt and effective antifungal treatment is essential to prevent disease progression.
When extensive lung infection occurs, comprehensive diagnostic evaluations must be performed first to determine the underlying cause, followed by timely and appropriate management.
