India faces a significant public health challenge with an estimated 10,000 to 12,000 children born with thalassemia major annually. Despite the availability of preventive measures, the country lacks a comprehensive carrier screening program. The shift from treatment to prevention, including genetic counseling and IVF with Preimplantation Genetic Testing, is crucial for reducing thalassemia births.
- 01India sees 10,000 to 12,000 new thalassemia major cases each year, with 35 to 45 million carriers.
- 02Thalassemia is preventable through carrier screening and genetic counseling, which are not uniformly implemented in India.
- 03Countries like Cyprus and Iran have successfully reduced thalassemia births through structured programs.
- 04IVF combined with Preimplantation Genetic Testing for Monogenic Disorders can help prevent thalassemia in future children.
- 05Public health policies must prioritize preventive reproductive genetics to lower the long-term costs of treatment.

Thalassemia major, a severe inherited blood disorder, affects an estimated 10,000 to 12,000 children born in India each year, contributing to a significant public health crisis. With 35 to 45 million carriers of the beta thalassemia trait in the country, most cases are preventable through early carrier screening and genetic counseling. Despite the proven success of countries like Cyprus and Iran in reducing thalassemia births through structured programs, India still lacks a national framework for carrier screening, leaving many couples unaware of their genetic risks. The financial burden of managing thalassemia is substantial, often leading to emotional and financial strain on families. Advances in reproductive technology, such as IVF combined with Preimplantation Genetic Testing for Monogenic Disorders (PGT-M), offer a preventive approach by allowing couples to select embryos free from thalassemia before pregnancy. To effectively combat thalassemia, India must integrate genetic screening into routine reproductive health discussions, particularly in high-prevalence areas, and expand genetic counseling infrastructure. By prioritizing preventive measures, the country can significantly reduce the number of children born with thalassemia, addressing both the emotional and financial costs associated with this condition.
