What the question wants
Give an account of how technology was used to manage the COVID-19 pandemic.
How to structure it
Detect, track, treat, vaccinate, continue life.
- Testing
- Tracking and data
- Treatment and health care
- Vaccines and CoWIN
- Keeping life going
- Limits
How to think it through
Testing: RT-PCR scaled from one lab (NIV Pune) to thousands; indigenous kits (Mylab); TrueNat; pooled testing. Tracking: Aarogya Setu, ICMR portal, drones for surveillance and disinfection, GIS hotspot mapping. Treatment: eSanjeevani telemedicine (crores of consultations), oxygen tracking, ventilators by startups, PPE scaled from zero to world's second-largest maker. Vaccines: Covishield, Covaxin, ZyCoV-D; CoWIN platform, 220 crore doses, digital certificates. Life: online education (DIKSHA), DBT cash transfers, ONORC, UPI. Limits: digital divide, privacy concerns.
Model answer
In January 2020, India could test for the new coronavirus in just one laboratory, the National Institute of Virology in Pune. Within a year it had thousands of labs, Indian-made test kits and, soon after, a digital platform that delivered more than 220 crore vaccine doses. Technology turned a slow response into a fast one.
Testing and detection
- RT-PCR capacity scaled across the country; Mylab produced the first Indian kit.
- TrueNat machines, first made for TB, used in district hospitals.
- Pooled testing to save kits; rapid antigen tests for speed.
- Genome sequencing through INSACOG to track variants.
Tracking and data
- Aarogya Setu app for contact alerts.
- GIS mapping of hotspots and containment zones.
- Drones for surveillance and disinfection.
- Supercomputer models used to forecast case surges.
Treatment and health care
- eSanjeevani telemedicine, which went on to serve crores of consultations.
- Oxygen tracking and supply software during the second wave.
- PPE kits: India went from almost no production to one of the world's largest makers within months.
- Low-cost ventilators from startups and DRDO.
Vaccines
- Covishield, Covaxin and ZyCoV-D, the world's first DNA vaccine.
- CoWIN for registration, scheduling and digital certificates, later shared with other countries.
- Vaccine Maitri exports to partner countries.
Keeping life going
- Online education through DIKSHA and SWAYAM.
- Cash transfers to Jan Dhan accounts and free grain under PMGKAY via ONORC.
- UPI and e-commerce for contact-free payments.
Limits
- Digital divide: many poor and rural people could not use apps or online classes.
- Privacy concerns over Aarogya Setu data.
- Misinformation spread online as fast as the virus.
Technology did not stop the virus, but it made India's fight against it faster, wider and fairer than it would otherwise have been.
Draw: A timeline: Jan 2020 one lab → mid-2020 PPE and testing scale-up → 2021 CoWIN vaccination.

DRDO’s indigenous AIP for Kalvari-class submarines reaches the Setting to Work Phase-2 stage
Diesel-electric submarines must come up often to run their engines and charge batteries, which can give away their position. Air Independent Propulsion (AIP) lets them stay underwater much longer. The DRDO’s Naval Materials Research Laboratory has built India’s own AIP, and its energy module began the Setting to Work Phase-2 activity at Larsen and Toubro’s Hazira yard on 24 October. For you, it links fuel cells, the Kalvari class and defence self-reliance.

NVS-03 launch on 30 October: can ISRO’s new satellite bring NavIC back to life?
ISRO will launch NVS-03, its third new-generation navigation satellite, on 30 October 2026, The Indian Express reported on 24 October. NavIC, India’s own GPS-like system, has not been able to give location data because only three satellites work, while positioning needs at least four. If NVS-03 works, NavIC can offer positioning again. It is a lesson in why strategic technology needs both satellites and users.
