I recently heard from a woman who lost her six-year-old daughter to Thalassemia. She went on to detail the grueling cycle of blood transfusions, the emotional exhaustion and the constant struggle her child endured as a result of the disease and the medical treatment. Then came the familiar revelation: the child’s parents were first cousins.
Tragedies like this expose a very important and critical, yet heavily ignored public health crisis in Pakistan. Despite the devastating toll of inherited genetic disorders, a vast majority of the population remains entirely unaware that marriages between close blood relatives make it much more likely for their children to inherit life-threatening genetic conditions, such as Thalassemia Major. According to the Punjab Thalassemia Prevention & Research Institute (PTGD), the high incidence of consanguineous unions, where first-cousin marriages alone account for 60% of all marital bonds, serves as a major factor behind the high prevalence of thalassemia in Pakistan. The reality here is incredibly harsh. According to the Thalassemia Federation of Pakistan, this manifests in 5,000 to 9,000 children born with Thalassemia every single year. Although marriage is a personal and cultural matter, the state also has a responsibility to ensure that citizens are equipped with basic health information before making life-changing decisions.
This is where law and policy can play a constructive role too. In recent years, Pakistan has begun taking legislative steps toward addressing this issue. Most notably, the Parliament has passed The Islamabad Capital Territory Compulsory Thalassemia Screening Act, 2025 under which couples in the federal capital are required to undergo a thalassemia screening test before their marriage can be formally registered. Some critics might view this as state overreach, however, the aim here is not to restrict marriage choices, but to ensure that individuals know if they carry the gene before starting a family.
By penalizing marriage registrars (Nikah Khwans) who fail to comply, the state is finally enforcing its own rules in public health policy.
The law also places responsibility on healthcare institutions treating thalassemia patients to identify and counsel their blood relatives, especially those of marriageable age. This policy aligns directly with standard medical best practices. Similarly, clinicians play a vital role in identifying these risks during pregnancy. Dr Sohail Ahmad, a renowned consultant gynecologist, highlights a critical clinical rule of thumb, where any pregnant women attending antenatal clinics who have low hemoglobin (anemia) and small red blood cells are advised to undergo further screening with an iron level check and a specialized hemoglobin test to identify the underlying cause and catch any potential thalassemia risks early in the pregnancy.
Furthermore, the law introduces ‘cascade screening’, a method requiring healthcare institutions to trace and counsel the immediate blood relatives of existing patients. The medical necessity of this clause is obvious; by targeting the immediate families of known patients, the state can catch carriers where they are most likely to be found. Moreover, the legislation emphasizes public awareness campaigns to educate people about inherited blood disorders and their prevention.
By penalizing marriage registrars (Nikah Khwans) who fail to comply and bypass these checks, the state is finally enforcing its own rules in public health policy. Although making this work on the ground in a country where marriage registration is often casual and unregulated will be an uphill battle, it is a fight the state can no longer avoid.
This approach is already working in other countries. Take the example of Cyprus, where mandatory premarital screening was instituted alongside the backing of local community institutions, the birth rate of children born with Thalassemia Major was successfully reduced by 96%, achieving near-zero new cases in subsequent decades. Even in Europe, the legislative tide is turning toward stricter public health measures; Sweden's parliament recently voted to legally ban marriages between first cousins, taking legal effect on July 1, 2026, marking a major policy shift driven by combined state concerns over genetic public health risks. These examples prove that when a government steps up to regulate public health instead of ignoring it, national disease burdens drastically decrease.
However, as groundbreaking as the 2025 Act is, it highlights a glaring disparity; this law currently only applies to Islamabad, and implementation across other cities and provinces isn’t yet present. Since health is a provincial subject following the 18th Amendment, Articles 141 and 142 of the Constitution confine Parliament’s legislative competence strictly to the federal capital; hence, this federal law is just a small fix for a massive national issue. According to hospital data cited by Al Jazeera, there are currently over 100,000 registered Thalassemia Major patients suffering nationwide, a number that grows by thousands each year outside the capital. A stronger legal framework around preventive genetic screening could help shift society from reacting to tragedy toward preventing it. True progress will not be measured by the laws passed in Islamabad, but by how quickly provincial assemblies replicate this framework.
We must stop treating thalassemia as an unavoidable twist of fate. Every child born with thalassemia represents not just a medical failure, but a policy failure. Pakistan has the legislative blueprint and the undeniable medical data; what it needs now is the political will to take this policy nationwide, shifting our society from merely mourning preventable tragedies to actively stopping them.
