Antibiotics have revolutionized modern medicine by effectively treating bacterial infections and significantly reducing global mortality. However, the emergence and rapid spread of antibiotic resistance have become a major public health concern worldwide. Antibiotic resistance occurs when bacteria develop mechanisms to survive exposure to previously effective drugs, largely due to the misuse and overuse of antibiotics in human healthcare, agriculture, and animal husbandry. This review examines key drivers of antibiotic resistance, including inappropriate prescribing, poor patient adherence, self-medication, and extensive agricultural use, all of which contribute to the selection and spread of resistant microorganisms. The impact of antibiotic resistance on infectious diseases is profound, leading to treatment failure, prolonged illness, increased mortality, and higher healthcare costs. Common infections such as pneumonia, tuberculosis, urinary tract infections, and hospital-acquired infections are becoming increasingly difficult to manage due to multidrug-resistant pathogens. In addition to clinical challenges, antibiotic resistance imposes significant economic and social burdens on healthcare systems and communities worldwide. This article also highlights essential prevention and control strategies, including antimicrobial stewardship programs, infection control practices, public education, and regulatory measures in agriculture. Furthermore, the importance of ongoing research into new antibiotics, rapid diagnostic tools, and alternative therapies such as bacteriophage therapy is emphasized. Addressing antibiotic resistance requires coordinated global action involving healthcare professionals, policymakers, researchers, and the public to preserve the effectiveness of existing antibiotics and ensure sustainable management of infectious diseases.
