👉 Modern infection, also known as infectious disease, refers to the presence and spread of pathogens—such as bacteria, viruses, fungi, and parasites—that cause illness in humans, animals, or plants. Advances in medical science, including improved diagnostics, vaccines, antibiotics, and hygiene practices, have significantly reduced the incidence and severity of many infectious diseases. However, the emergence of antibiotic-resistant bacteria and the rapid global spread of pathogens due to travel and trade continue to pose significant challenges. Modern medicine also emphasizes prevention through public health measures, such as vaccination programs and sanitation, to control and mitigate the impact of infections on populations worldwide.
