I think you mean the coronavirus pandemic of 2019. Hopefully that clarifies!
Airway blockage or limitation is a hallmark of the group of chronic, irreversible respiratory disorders known as a chronic obstructive pulmonary disease (COPD). It is not treatable or contagious. Reduced pulmonary airflow brought on by elevated inflammation characterises asthma and chronic obstructive pulmonary disease (COPD).
Two primary phenotypes have been established based on clinical, pathological, and radiological characteristics:
Emphysema type A and type B patients are referred to as "pink puffers" and "blue-bloaters," respectively (chronic bronchitis)
Dyspnea is the most common symptom in Type A patients, while cough and hypersecretion are mild. The main causes of the decreased diffusing capacity for carbon monoxide (DLCO) and frequently enlarged lung volumes in Type A patients include non-homogeneous ventilation and ventilation-perfusion mismatch. Type A patients also seldom have hypercapnia or recurrent heart failure.
Mucous hypersecretion is the predominant symptom of type B patients, although dyspnea is mild. While lung capacities are not expanded and carbon monoxide diffusing ability is often conserved, type B patients frequently exhibit hypercapnia, hypoxia, secondary pulmonary hypertension, and cardiovascular comorbidities.

Answer:
renal column
Explanation:
The renal column is also known as Berlin column . It is a medullary expansion of the renal cortex in the middle of the renal pyramids. It enables the cortex to be better tied down. Every section comprises of lines of veins and urinary cylinders and a sinewy material.each renal columns comprises of lines of veins and urinary cylinders and a sinewy material.
