Inflammatory lesions in general are clinical symptoms such as fever, cough, sputum, local edema, pain, etc. that occur after the body has been infected with bacteria or viruses and other pathogens, usually due to infection with bacteria or viruses and other pathogens such as mycoplasma and chlamydia. The most common infections are upper respiratory tract infections such as influenza, viral flu, and lobar pneumonia or lung abscess due to Staphylococcus aureus infection, as well as mycoplasma pneumonia and chlamydia pneumonia after mycoplasma and chlamydia infection. In the case of adenovirus infection, there is also a possibility of viral pneumonia in patients. In these cases, the pathogen should be actively identified before considering the next step of treatment. For viral infections, active supportive therapy is usually needed to maintain immunity and symptomatic treatment, and recovery is usually slow in about 1-2 weeks. For bacterial infections, fever and elevated white blood cells are often associated with the infection, and anti-inflammatory treatment with sensitive antibiotics is required.
