COVID-19 pandemic has caused unprecedented devastation worldwide. However, technological advancements are being availed readily to win over the crisis. Give an account of how technology was sought to aid management of the pandemic.
Approach · directive: “give an account”
What it asks · Give an account of the technologies used against COVID-19: testing and sequencing, tracing, treatment and vaccines, telemedicine, logistics, and continuity of work, learning and welfare.
Open with · The pandemic showed how quickly technology can be mobilised in a crisis, from genome sequencing and contact tracing to vaccines and online delivery of services.
Cover
- Detection: RT-PCR and rapid antigen tests, pooled testing, genome sequencing, and AI-aided reading of chest images.
- Tracing and surveillance: the Aarogya Setu app, GIS maps of containment zones, drones for surveillance and announcements, and thermal screening.
- Treatment: telemedicine such as eSanjeevani, indigenous ventilators, PPE and testing kits, plasma and repurposed-drug trials, and robots and UV disinfection in hospitals.
- Vaccines: developed in record time on mRNA, vector and inactivated-virus platforms; India's Covaxin and Covishield, with CoWIN for registration and certificates.
- Continuity: work from home and video conferencing, online classes (DIKSHA, SWAYAM), digital payments and DBT to reach the poor during lockdown.
- Supply: Lifeline UDAN flights and drones to carry medical supplies, and online portals to track hospital beds and essential goods.
- Limits: the digital divide, privacy concerns over tracing apps, misinformation, and dependence on imported inputs; technology works only with strong public-health capacity.
Close with · Technology helped detect, treat and cushion the crisis, but it works best with strong public-health systems, privacy safeguards and equal access.

Model answer · 235 words (UPSC limit 250) · Minimalist IAS
The pandemic showed how fast technology can be mobilised in a crisis: from genome sequencing and contact tracing to vaccines developed in under a year and public services delivered online.
Detection and surveillance
- Testing: RT-PCR and rapid antigen kits, pooled testing and genome sequencing tracked the virus and its variants; AI-aided reading of chest images supported diagnosis.
- Tracing: the Aarogya Setu contact-tracing app, GIS maps of containment zones, thermal screening, and drones for surveillance and public announcements.
Treatment and hospitals
- Telemedicine through eSanjeevani kept care going during lockdown; indigenous ventilators, PPE and testing kits were scaled up; robots and UV disinfection reduced staff exposure; trials tested plasma and repurposed drugs.
Vaccines
- Vaccines came in record time on mRNA, viral-vector and inactivated-virus platforms; India's Covishield and Covaxin were delivered through CoWIN, which handled registration, slots and certificates.
Continuity of life and welfare
- Work from home and video conferencing, online classes through DIKSHA and SWAYAM, digital payments, and direct benefit transfers that reached the poor during lockdown.
Supply and logistics
- Lifeline UDAN flights and drones moved medical supplies, and online portals tracked hospital beds and essential goods.
Limits
- The digital divide excluded many from online classes and vaccine slots; tracing apps raised privacy concerns; misinformation spread as fast as facts; and imported inputs created dependence.
Technology helped detect, treat and cushion the crisis, but it worked only where public-health capacity, privacy safeguards and equal access backed it.
