Experts call for shifting the narrative on Antimicrobial Resistance from statistics to human connection

Antimicrobial Resistance (AMR) is being reframed as a communication crisis rather than just a medical one. Since the 2010 discovery of the NDM-1 enzyme, the focus has been on alarming global statistics, which often leads to public apathy. Experts now advocate for a narrative centered on the 'human microbiome'—the trillions of beneficial microbes that are disrupted by unnecessary antibiotic use. By emphasizing how antibiotics can harm individual health, immunity, and mental well-being, health advocates hope to move from a 'language of war' against bugs to a 'language of wisdom' in preserving life-saving drugs.

  • NDM-1 (New Delhi Metallo-beta-lactamase) brought global attention to AMR in 2010.
  • Unnecessary antibiotic use can disrupt the human microbiome for months, affecting long-term health.
  • Reframing AMR as a solvable, individual health challenge is more effective than using abstract, large-scale statistics.

Experts Propose Biannual Vaccination Strategy to Combat India's Substantial Influenza Burden

India faces a significant but underestimated burden of influenza, with two distinct seasonal peaks: winter (January-March) and post-monsoon (July-September). Current influenza vaccines provide short-lived protection, with antibody levels declining significantly within three to six months. Because the virus undergoes constant antigenic drift, experts suggest that a single annual shot is insufficient for year-round protection in India's tropical climate. The article advocates for a biannual vaccination schedule (June and November) and the inclusion of influenza vaccines in the Universal Immunisation Programme (UIP) to reduce hospitalisations and deaths, particularly among children and the elderly who are most at risk.

  • India experiences two influenza peaks, unlike temperate countries which typically have one winter peak.
  • Vaccine effectiveness drops significantly within 90 days, leaving populations vulnerable during the second annual peak.
  • Less than 5% of Indians currently receive influenza vaccines due to a lack of government policy and public awareness.

Informal sector dominance and regulatory gaps hinder formal e-waste recycling in India

Despite government efforts to promote formal e-waste recycling through the Extended Producer Responsibility (EPR) framework, the informal sector continues to play a dominant role. Millions of tons of electronics are disposed of annually, but only about one-third is processed through proper channels. The informal sector often harvests components for repair rather than recycling, which disrupts the 'circular economy' and leads to environmental hazards. Policymakers face a dilemma as informal set-ups provide livelihoods but lack the technology for safe metal extraction. Strengthening the EPR framework and improving material traceability are essential to secure critical minerals like lithium and cobalt.

  • India generated approximately 4.17 million metric tonnes of e-waste in 2022, but only a third is processed formally.
  • The Extended Producer Responsibility (EPR) framework requires manufacturers to collect and recycle their end-of-life products.
  • Informal recyclers often prioritize component harvesting for repairs over the extraction of precious metals.
