Revision summary
Sickle cell disease (SCD) is a major genetic burden in India's tribal belt, driven by high carrier frequencies (HbS allele) linked historically to endemic malaria selection pressure. States such as Madhya Pradesh, Chhattisgarh, and Gujarat have ramped up targeted screening, genetic counselling, and treatment facilities under national missions. The National Sickle Cell Anaemia Elimination Mission aims to eradicate the disease by 2047 through universal screening and community awareness. Integrating anthropological insights into public health delivery remains critical for addressing tribal health disparities.

Introduction
Sickle cell disease (SCD) is a debilitating monogenic blood disorder characterized by abnormal hemoglobin, disproportionately affecting indigenous (tribal) populations in central and western India. High carrier frequencies in these geographically isolated and endogamous groups reflect historical balancing selection against falciparum malaria.
Body
Epidemiological Profile and Prevalence
- Genetic concentration: The highest prevalence of the sickle cell trait (HbAS) and disease (HbSS) is concentrated in the central tribal belt, spanning Madhya Pradesh, Chhattisgarh, Maharashtra, Gujarat, and parts of Odisha and Rajasthan.
- Carrier frequency: Studies indicate that the carrier frequency ranges from 1% to over 40% in certain endogamous tribal groups such as the Bhils, Gonds, Baigas, and Korkus.
- Malaria hypothesis: High endemicity of Plasmodium falciparum malaria in these forested regions historically provided a survival advantage to heterozygotes (balanced polymorphism), perpetuating the allele.
State-Level Interventions and Policy Initiatives
- Screening and diagnosis: Affected states have deployed point-of-care solubility tests and HPLC (High-Performance Liquid Chromatography) testing during community outreach camps and ASHAs-led drives.
- National mission linkage: States are actively implementing the National Sickle Cell Anaemia Elimination Mission (launched in 2023), aiming to screen 7.4 crore people in vulnerable age groups over three years.
- Counselling and management: Specialized day-care centres, hydroxyurea therapy distribution, and pre-marital genetic counselling cards are being rolled out in high-burden districts to manage morbidity and reduce births of affected children.

Conclusion
Addressing sickle cell disease among tribal groups requires sustained biomedical interventions combined with culturally sensitive health communication. Bridging genetic screening with community engagement will be vital to achieve the national goal of eliminating sickle cell anaemia as a public health problem by 2047.

Tribal situation in India
• British officials like J.H. Hutton and T.C. Hodson wrote detailed monographs on North-East tribes, focusing on kinship, material culture, and oral traditions. • Early census operations and George Abraham Grierson's Linguistic Survey of India mapped the region's diverse racial affinities and language families. • These records preserved endangered mythologies, customary laws, and folklore during a period of rapid administrative change. • However, this scholarship served imperial goals of governance, using "divide and rule" tactics that hardened fluid tribal identities into rigid groups. • Victorian unilinear evolutionism wrongly viewed tribes as static "primitive specimens" rather than dynamic societies. • Modern anthropology relies on this historical baseline while correcting colonial biases through indigenous agency and reflexivity.

Tribal situation in India
Tribal India clusters in the Himalaya, North-East, middle Indian uplands, western hills, southern enclaves, and islands. North-East institutions include morung, Khasi matriliny, Inner Line, and Sixth Schedule councils. Middle India shows khuntkatti, manjhi, sarna, and a tribe–caste continuum under the Fifth Schedule. Western Bhils are more peasantised; southern Toda and Chenchu keep specialised dairies or foraging. Island PVTGs are bands with a separate contact ethic from Nicobarese horticultural villages.

Bio-genetic variability of Indian tribes
Tribal situation in India
Indian tribes vary genetically by region and language family. They are not Risley’s or Guha’s single tribal type. Local castes may be closer than distant tribes. Siwalik apes are not tribal ancestors. Health policy must follow local variation.
