Clinical studies of severe COVID‑19 have
highlighted dysregulated host immune responses that contribute significantly to
lung pathology. When COVID-19 causes a severe infection, it is common for
immune pathways to show dysregulation.

lung pathology. When COVID-19 causes a severe infection, it is common for
immune pathways to show dysregulation.

Which mechanism best accounts for the tissue
damage observed in severe cases?

Accepted Answer

Excessive
activation of inflammatory cascades leads to immune‑driven lung damage

Answer

Insufficient
inflammatory signalling allows uncontrolled viral replication without injury

Answer

Interferon
suppression uniformly protects lung tissue during viral infections

Answer

Reduced
cytokine production prevents immune cell recruitment to the lungs
