Mains Probable Question

Discuss the significance of India's efforts in developing gene therapy for sickle cell disease and its impact on public health, particularly among Scheduled Tribes.

Model Answer

Introduction

Sickle cell disease (SCD) is a genetic blood disorder characterized by the presence of abnormal hemoglobin, leading to distorted (sickle-shaped) red blood cells. These cells can obstruct blood flow, causing severe pain, organ damage, and increased risk of infection. SCD has a high prevalence among the Scheduled Tribes in India, making it a significant public health concern. India’s recent efforts to develop gene therapy for SCD using CRISPR-Cas9 technology represent a major advancement in the country's healthcare strategy. This initiative aims to eradicate the disease by 2047 and improve the quality of life for affected populations. This essay explores the significance of these efforts and their impact on public health, particularly among the Scheduled Tribes.
