Pre & Mains Notes

1. H1N1 in India: No New Strain, Existing Vaccines Sufficient WHAT HAPPENED ICMR reported that the H1N1 viruses currently circulating in India belong to the A/Missouri/11/2015 (H1N1)pdm09-like virus strain, with no new H1N1 strain identified. CORE ISSUE India is witnessing a seasonal rise in H1N1 cases, but current circulating strains remain well matched with available vaccines. KEY DETAILS - Current strain: Predominantly A/Missouri/11/2025 (H1N1)pdm09-like virus, with the lineage circulating since 2025. - Cases rising: Delhi reported over 1,777 confirmed H1N1 cases by August 2026, while Kerala and Karnataka also reported rising cases. - No new strain: ICMR found no evidence of a new or more dangerous H1N1 strain; infections are likely to decline as the current strain continues circulating. - High-risk groups: Children, elderly people, pregnant women and those with underlying medical conditions face higher risks of complications. WHY IT MATTERS Highlights the importance of seasonal influenza surveillance, vaccination and early treatment, particularly for vulnerable populations. 2. Polysilicon Manufacturing: Building India’s Solar Supply Chain WHAT HAPPENED MNRE is formulating a dedicated subsidy scheme to establish 30 GW of domestic polysilicon manufacturing capacity by 2030. CORE ISSUE Reducing India’s dependence on imported upstream solar materials by developing domestic polysilicon production. KEY DETAILS - What is polysilicon? A high-purity crystalline form of silicon and the key upstream feedstock for solar PV ingots/wafers and semiconductors. - Manufacturing: Quartz/silica → metallurgical-grade silicon → chlorosilanes → purification → ultra-high-purity polysilicon through Siemens Process or FBR. - High purity: Solar-grade polysilicon generally requires 6N–9N purity, while semiconductor-grade requires even higher purity. - Strategic importance: Domestic production can strengthen India’s solar manufacturing and semiconductor value chains, while reducing vulnerability to imported upstream materials. WHY IT MATTERS Polysilicon is a critical link between raw silicon and finished solar cells/semiconductors. Building domestic capacity can improve India’s renewable-energy supply-chain resilience and strategic autonomy.

Pre & Mains Notes

1. Mobile Manufacturing Scheme: ₹62,500 Crore Push WHAT HAPPENED The Centre has introduced a ₹62,500-crore, five-year mobile manufacturing scheme to scale domestic production, deepen component sourcing and promote Indian smartphone brands. CORE ISSUE Moving India’s mobile sector from assembly-led growth to deeper domestic manufacturing and brand development. KEY DETAILS - Two tracks: Supports large-scale mobile manufacturers/EMS companies and separately provides incentives for Indian smartphone brands. - PLI successor: Manufacturers must meet turnover and domestic production thresholds; incentives are linked to incremental sales over a baseline. - Domestic brands: Indian-owned brands can receive an additional 5% incentive on incremental sales; products made and designed in India can get further design/R&D incentives. - Strategic shift: Focuses on developing domestic supply chains, intellectual property, design capabilities and brands capable of competing with global players. WHY IT MATTERS Aims to reduce dependence on imported components and move India higher up the global electronics value chain, from assembly to design, components and Indian brands.
