Step-by-step explanation:
Hypersensitivity and Flea Allergic Dermatitis in Animals
Allergies are the result of the immune system's hypersensitivity to substances that are typically harmless and can result in conditions such as hay fever, food allergies, and atopic dermatitis. When an individual who is already sensitized to an allergen comes into contact with it again, they might experience a type I hypersensitivity reaction, which can be immediate and severe. Flea allergic dermatitis is a common allergic skin disease in animals, particularly in cats and dogs, with dogs often more commonly affected. This condition arises when an animal that has an allergy to flea saliva is bitten by a flea.
Managing the symptoms of allergies can involve a variety of treatments depending on the severity and type of allergic reaction. Common treatments include antihistamines, corticosteroids, and avoidance of the known allergens. In the case of flea allergic dermatitis, treatments may include flea prevention and control measures, as well as medication to control itching and inflammation.
