Allergy Viral

What happens quite often, the cause of diseases in the form of allergies is a huge number of different viruses (microorganisms) that affect the body’s immune system. The spread of viral and bacterial infections affects the development of an allergic reaction. Bacteria and viruses reach the upper layers of the respiratory tract, which provokes and reduces protection against diseases and various attacks that can cause allergies even in a healthy person. An abnormal hypersensitivity reaction manifests itself in a variety of ways, such as soft tissue swelling or anaphylaxis, immune disorders, viral infections, or decreased defenses. A certain disease can take the form of an allergy when a virus disrupts the immune system. Processes after contracting an infection can take a long time and sometimes cause an allergic reaction.
