What is a condition that occurs when pathogens in the body multiply and damage body cells?

A condition that occurs when pathogens in the body multiply and damage body cells is known as an infection. Infections can be caused by various types of pathogens, including bacteria, viruses, fungi, and parasites. As these microorganisms multiply, they can disrupt normal cellular functions, leading to inflammation and tissue damage, which may result in symptoms such as fever, pain, and fatigue. Treatment often involves the use of antibiotics, antivirals, or antifungals, depending on the type of pathogen involved.
