Steps taken for Prevention and Control of Vector-Borne Diseases

1. At a Glance

• Vector-Borne Diseases (VBDs) in India: six diseases tackled under the National Vector Borne Diseases Control Programme (NVBDCP) — Malaria, Dengue, Chikungunya, Japanese Encephalitis (JE), Lymphatic Filariasis, and Kala-azar [2].
• Administered by the National Centre for Vector Borne Diseases Control (NCVBDC) under the Ministry of Health and Family Welfare (MoHFW) within the umbrella of the National Health Mission (NHM) [1][2].
• High UPSC salience: intersects GS-II (health governance, centre-state) and GS-III (S&T, disease ecology, climate-health linkage).

2. Why in the News

• 17 March 2026 PIB release by MoHFW reiterating steps for prevention and control of VBDs, including free JE vaccine under UIP and Sentinel Surveillance network for Dengue and JE [1].
• Union Health Minister J P Nadda reviewed Dengue and Malaria preparedness with States to galvanise preventive activities [3].

3. Background & Evolution

• National Malaria Control Programme launched 1953; rechristened National Malaria Eradication Programme (1958).
• NVBDCP constituted in 2003-04 by merging vertical programmes (malaria, filaria, kala-azar, JE, dengue; chikungunya added later) [2].
• Renamed/restructured as National Centre for Vector Borne Diseases Control (NCVBDC) under Directorate General of Health Services [2].
• National Framework for Malaria Elimination (2016-2030) aligned with WHO Global Technical Strategy; revised target: zero indigenous malaria cases by 2027, sustain elimination by 2030 [2].

4. Core Static Facts

• Implementing body: NCVBDC, Dte.GHS, MoHFW; funded via NHM (Centre-State cost sharing) [1][2].
• Diseases covered (6): Malaria, Dengue, Chikungunya, JE, Lymphatic Filariasis, Kala-azar [2].
• Elimination targets: Malaria — 2030; Kala-azar — eliminated as public health problem (<1 case per 10,000 at block level); Lymphatic Filariasis — elimination via MDA [2].
• JE Vaccine: Free under Universal Immunization Programme (UIP); 2 doses at 9-12 months and 16-24 months; given in endemic districts [1][3].
• Surveillance network for Dengue & JE: Sentinel Surveillance Hospitals (SSH) + Apex Referral Laboratories (ARLs); GoI supplies test kits free [1][3].
• Capacity (overall VBD diagnostics): 869 SSH and 27 ARLs provide free testing; >5,520 Dengue diagnostic kits supplied to States in 2025 [3].
• JE-specific: 28 SSH identified, kits provided free by MoHFW [3].
• Supportive interventions: Behaviour Change Communication (BCC), Inter-sectoral Convergence, Human Resource Development [1].
• Constitutional anchor: Public Health is a State subject (Schedule VII, List II, Entry 6) [1].

5. Multi-Dimensional Analysis

• Administrative / Federal: Centre provides financial & technical assistance via NHM; States execute (case management, fogging, insecticides) — classic cooperative federalism model with implementation asymmetry [1][2].
• Scientific / Technological: Integrated Vector Management (IVM) — Indoor Residual Spraying (IRS), Long-Lasting Insecticidal Nets (LLINs), larvivorous fish, source reduction; rapid diagnostic kits (NS1, IgM ELISA) [2][4].
• Social / Equity: Kala-azar concentrated in Bihar, Jharkhand, WB, UP; JE burden in Assam, UP, Bihar, WB — predominantly tribal/poor rural; equity gap in BCC and ASHA reach [2].
• Environmental / Climate: Urbanisation, monsoon variability, stagnant water, deforestation alter Aedes/Anopheles ecology; WHO flags climate change as expanding VBD geography [4].
• Geopolitical: WHO Global Vector Control Response (GVCR) 2017-2030 mirrored by India; SE Asia Region (SEARO) collaboration on cross-border malaria [4].

6. Recent Developments (last 12-18 months)

• 17 Mar 2026 — MoHFW reiterated JE vaccination, SSH/ARL surveillance, and BCC strategy [1].
• 2025 — >5,520 Dengue diagnostic kits supplied to States; J P Nadda chaired Dengue-Malaria review [3].
• World Malaria Day 2025 observed with renewed push toward 2027 zero-indigenous-case milestone [2].
• Joint NVBDCP-WHO national consultation on Integrated Vector Management aligned with GVCR [4].

7. Prelims Hooks

• NVBDCP covers 6 VBDs: Malaria, Dengue, Chikungunya, JE, Lymphatic Filariasis, Kala-azar [2].
• Nodal body: NCVBDC (renamed from NVBDCP HQ), under Dte.GHS, MoHFW [2].
• JE vaccine under UIP: 2 doses at 9-12 months and 16-24 months [1].
• 869 Sentinel Surveillance Hospitals + 27 Apex Referral Labs for VBD diagnosis [3].
• 28 Sentinel Surveillance Hospitals specifically for JE diagnosis [3].
• India's malaria elimination target year: 2030 (zero indigenous cases by 2027) [2].
• Kala-azar vector: Phlebotomus argentipes sandfly; JE vector: Culex mosquito; Dengue/Chikungunya: Aedes aegypti.
• Public Health is a State subject — Centre supports via NHM [1].
• Three supportive interventions: BCC, Inter-sectoral Convergence, HRD [1].
• WHO global framework: Global Vector Control Response 2017-2030 [4].
• Funding route: National Health Mission, MoHFW [1].
• Diagnostic kits for Dengue & JE provided free of cost by GoI [1].

8. Mains Relevance

• GS-II: Issues relating to development & management of Social Sector/Services — Health; Government policies & interventions.
• GS-III: Science & Technology — health technology; Disaster Management (epidemic preparedness).
• Probable stems: 1. "Despite multiple vertical disease control programmes, India's vector-borne disease burden persists. Examine the structural and ecological reasons." 2. "Discuss the role of Integrated Vector Management in achieving India's 2030 malaria elimination target." 3. "Public health being a State subject often hampers uniform vector-borne disease control. Critically analyse."

10. Common Errors / Trap Areas

• NVBDCP vs NCVBDC — same programme, renamed centre; do not treat as separate.
• JE vaccine schedule — 2 doses (not 3); ages 9-12 mo & 16-24 mo, not at birth [1].
• Mosquito-disease pairing: Aedes → Dengue/Chikungunya/Zika; Culex → JE/Filaria; Anopheles → Malaria; Phlebotomus (sandfly) → Kala-azar (not a mosquito).
• Confusing Sentinel Surveillance Hospitals (869) with JE-specific SSH (28) [3].
• Malaria target: eliminate by 2030, not eradicate; WHO certifies elimination after 3 consecutive years of zero indigenous cases.
• Public health is State subject — Centre cannot directly implement, only fund/coordinate [1].
