Current Status of β-Thalassemic Burden in India.

Thalassemia is a major public health concern in India. The thalassemic burden in India is high, with an estimated 100,000 patients diagnosed with β-thalassemia syndrome. However, the exact number is unknown because of the absence of National Registries for patients. India alone contributes to approximately 25% of the global β-thalassemia burden. A possible option to control this burden is to endorse education and awareness programs, compulsory prenatal screening, and develop suitable facilities for genetic counseling, and availability of cost-effective diagnostic tests in India, especially in rural areas. In addition to the various clinical complications associated with thalassemia, lifelong intervention creates mental and physical trauma in patients and their relatives. Government and nongovernment organizations have initiated screening programs to prevent thalassemia. However, prenatal screening is not mandatory, and the reachability of screening programs in rural areas is yet to begin. This review article will discuss the progress in thalassemia research in India, including its prevalence, spectrum of β-thalassemia mutations, preventive and therapeutic measures, and awareness programs. More importantly, we will discuss the need and roadmap to strengthen prevention programs in India.
