U84.9: Resistance to unspecified antimicrobial drugs

Resistance to unspecified antimicrobial drugs, also known as antimicrobial resistance (AMR), is a condition where bacteria, viruses, parasites or fungi evolve over time and no longer respond to medicines such as antibiotics, making infections harder to treat and increasing the risk of disease spread, severe illness or death. This phenomenon usually occurs when drugs are used too often or incorrectly. Common symptoms vary based on the specific type of infection, but could include fever, sore throat, cough, and skin sores. If the body's immune system cannot control the bacteria or other pathogens due to their resistance to drugs, the infection can progressively get worse and potentially affect multiple systems in the body. Effective treatment becomes increasingly difficult, as options for treating these resistant infections are limited and may require higher doses or stronger types of medications. Antimicrobial resistance is a serious global health issue that could impact anyone, of any age, in any country.
