Antimicrobial resistance poses global health threat
Antimicrobial resistance (AMR), where microbes become resistant to drugs, is a major global health concern. It is driven by overuse of antimicrobials and poor sanitation, hindering infection treatment and increasing mortality.
Antimicrobial resistance (AMR), the phenomenon where microbes evolve to resist drugs designed to kill them, is classified as one of the top 10 global public health threats by the World Health Organization (WHO). This growing resistance makes common infections harder to treat and increases the risk of disease spreading, severe illness, and death.
The primary drivers of AMR are the overuse and misuse of antimicrobial medicines, including antibiotics, antivirals, antifungals, and antiparasitics. Factors such as inadequate access to clean water and sanitation, along with poor infection prevention and control practices in healthcare settings and agriculture, also significantly contribute to the spread of resistant pathogens.
Beyond public health, AMR imposes a substantial economic burden. Longer hospital stays, the need for more expensive second- and third-line treatments, and increased mortality all strain healthcare systems and reduce economic productivity. Without effective antimicrobials, modern medical procedures like complex surgeries, cancer chemotherapy, and organ transplants would become significantly riskier.
The situation is compounded by a dwindling pipeline of new antimicrobial drugs. To combat this crisis, the WHO emphasizes the need for a coordinated, multi-sectoral approach, often referred to as 'One Health'. This involves improving antimicrobial stewardship, enhancing infection prevention, investing in research and development for novel treatments, and increasing public awareness about responsible antimicrobial use.
