INFLUENZA INVASION: Viral Attack on the Lung

Описание: INFLUENZA INVASION: Viral Attack on the Lung.

Influenza is a highly contagious respiratory virus that begins its attack deep within the delicate tissues of the lungs. The infection starts when viral particles latch onto receptors on the surface of pneumocytes—thin, vulnerable lung cells essential for gas exchange. Once attached, the virus slips inside and rapidly hijacks the cell’s machinery, forcing it to manufacture hundreds of new viral copies. As these particles accumulate, the overrun cell ultimately bursts, spilling fresh viruses throughout the surrounding air sacs.

This destructive process accelerates as neighboring cells fall victim, triggering a powerful inflammatory response. Fluid and immune cells begin leaking from tiny capillaries into the alveoli, filling the spaces that should be occupied by air. As the lungs become congested with this inflammatory fluid, oxygen struggles to cross into the bloodstream. The body becomes progressively deprived of oxygen, leading to shortness of breath, chest tightness, fever, and the potential for serious complications such as viral pneumonia or respiratory failure. Influenza’s rapid and aggressive invasion underscores the importance of vaccination, early treatment, and preventive measures during seasonal outbreaks.
