👉 Infections are caused by various pathogens, including bacteria, viruses, fungi, and parasites, which invade and multiply within the body, often leading to illness or disease. When a pathogen enters the body, it can trigger an immune response, but if the infection is severe or the immune system is compromised, it can result in infection. This process involves the pathogen invading tissues, evading or overcoming the body's defenses, and causing damage or dysfunction. Common symptoms of infection include fever, inflammation, pain, and swelling, which are the body's attempts to fight off the invader. Effective treatment typically involves antibiotics for bacterial infections, antiviral medications for viral infections, antifungal agents for fungal infections, and antiparasitic drugs for parasitic infections. Understanding the nature of infection is crucial for developing appropriate preventive measures and therapeutic strategies to protect health and prevent the spread of disease.
