Model answer

Written by UPSC Answer Check against this question's marking rubric, to the expected length. UPSC does not publish answers for Mains — this is one way to score well, not an official key.

End TB Strategy. The End TB Strategy moves TB control beyond vertical DOTS to an integrated, patient-centred, rights-based, evidence-based, multi-sectoral approach aligned with SDG 3.3. Its three pillars are: (1) integrated, patient-centred prevention, diagnosis, treatment and care; (2) intensified TB research and development; and (3) strong health systems with predictable financing. Its thirteen components are prevention (including BCG, preventive therapy, contact tracing and nutrition), diagnosis, treatment, care and support; research, diagnostics, vaccines and new treatments; and health systems, community/civil-society engagement, infection control and quality use of medicines, financing, and governance with data and surveillance. Major barriers are MDR/XDR-TB and drug resistance, diagnostic delays, stigma, poverty, weak primary care, funding gaps, and COVID-19 disruption.

HPV vaccination in India. India carries about 12% of global cervical cancer burden (≈77,000 new cases and 41,000 deaths annually). Impact so far is limited but measurable: Tamil Nadu’s demonstration project has vaccinated over a million girls, with reported coverage around 70% in pilot districts, and SIIP inclusion plus NTAGI recommendations have moved HPV vaccine for girls 9–14 toward national rollout. National coverage remains low, so population impact is still potential rather than realized; high coverage could prevent 70–80% of cervical cancer. Because most oncogenic HPV infections occur soon after sexual debut, pre-exposure vaccination of 9–14-year-olds is the most cost-effective route to a measurable fall in cervical cancer in India.

Available HPV vaccines and schedules. Available vaccines are bivalent Cervarix (HPV 16/18), quadrivalent Gardasil (6/11/16/18), and nonavalent Gardasil 9 (adds 31/33/45/52/58). For 9–14 years, a two-dose schedule is used, usually 0 and 6–12 months; for 15–26 years, three doses at 0, 1–2 and 6 months. Manufacturer schedules are Cervarix 0, 1–2, 6 months; Gardasil and Gardasil 9 0, 2, 6 months, with the same two-dose option for younger adolescents.

Breast lump. If malignant, examination may show a hard, irregular, fixed lump; skin dimpling, tethering, ulceration or peau d’orange; nipple retraction or bloody discharge; enlarged hard/matted axillary nodes, and possibly contralateral nodes. Investigation is by triple assessment: clinical examination, imaging (mammography and ultrasound; MRI when indicated), and cytology/histology (FNAC or, preferably, core biopsy), followed by ER/PR/HER2 receptor testing. In modified radical mastectomy, preserve pectoralis major; pectoralis minor may be preserved (Auchincloss) or divided (Patey), while the long thoracic nerve to serratus anterior, thoracodorsal nerve to latissimus dorsi, and intercostobrachial nerve must be protected.

The way forward is therefore to operationalize End TB components, scale HPV vaccination with coverage monitoring, and apply disciplined triple assessment and nerve-sparing MRM.

What "Discuss" is asking you to do

Lay the issue out from more than one side — how it arose, what is claimed for it, what is held against it, and where it now stands. UPSC attaches discuss to broad topics with several live dimensions, so coverage of the dimensions earns more than the strength of your opinion.

Structure that answers it

Set the issue up → the case as it is made → the case against → the dimension both sides leave out → where the balance now lies

Where marks are lost

Listing facts with no thread between them, or arguing one side throughout and calling it a discussion.
