Community factors in the development of antibiotic resistance.

The global impact of antibiotic resistance is potentially devastating, threatening to set back progress against certain infectious diseases to the pre-antibiotic era. Although most antibiotic-resistant bacteria originally emerged in hospitals, drug-resistant strains are becoming more common in the community. Factors that facilitate the development of resistance within the community can be categorized as behavioral or environmental/policy. Behavioral factors include inappropriate use of antibiotics and ineffective infection control and hygiene practices. Environmental/policy factors include the continued use of antibiotics in agriculture and the lack of new drug development. A multifaceted approach that includes behavioral strategies in the community and the political will to make difficult regulatory decisions will help to minimize the problem of antimicrobial resistance globally.
