👉 Infections occur when harmful microorganisms, such as bacteria, viruses, fungi, or parasites, invade and multiply within the body, disrupting normal cellular functions and causing illness. These pathogens can enter through various means, including cuts, wounds, or mucous membranes, and often thrive in environments where the immune system is compromised. When the body's defenses fail to eliminate the infection, it can lead to inflammation, tissue damage, and systemic symptoms like fever, pain, and fatigue. Treatment typically involves antibiotics for bacterial infections, antiviral medications for viral ones, antifungal agents for fungal infections, or antiparasitic drugs for parasitic conditions. In severe cases, hospitalization may be necessary to manage complications, provide supportive care, and ensure the body can effectively fight off the infection.
