Basic definition of infection refers to the harm caused by pathogenic microorganisms such as bacteria, viruses, fungi, parasites, or other infectious agents entering the human body. Some infections
Viral infections are caused by viruses that invade the body's cells and can range from mild, self-limiting illnesses to severe and life-threatening diseases. While many common viral infections
Unlike viral infections, most bacterial infections can be effectively treated with antibiotics, although the growing emergence of antimicrobial resistance has become a major global health concern.
Fungal infections can range from superficial skin and nail infections to severe invasive diseases affecting internal organs, particularly in immunocompromised individuals. These infections trigger
