Nature

Congenital deformities and disorders are either: (a) attributable to faulty genetic information which affects the development of the foetus and shows at birth or in early childhood; the malformation may be inherited (be familial) or arise spontaneously in the individual egg, sperm or embryo;or (b) arising from inherited genetic information from other internal or external factors, such as hormonal disturbance, drugs, toxins and mutagens (collectively called teratogens) and physical injury.

Types of common congenital anomalies include atresia (a normal opening or tube in the body is closed or absent), stenosis (abnormal narrowing of a bodily canal or passageway), malpositioning, malformation, discolouration or absence of an organ. Cysts, and accessory or multiple organs occur. Organs may show congenital malfunction.

Background

The global significance of congenital abnormalities emerged in the mid-20th century, notably after the thalidomide tragedy of the 1960s, which revealed the vulnerability of fetal development to environmental factors. Subsequent international surveillance, such as the establishment of the International Clearinghouse for Birth Defects Surveillance and Research in 1974, highlighted the widespread prevalence and diverse causes of these conditions, prompting coordinated research and policy responses across continents.

Incidence

Congenital abnormalities affect an estimated 6% of all live births worldwide, accounting for approximately 7.9 million children annually. The burden is particularly high in low- and middle-income countries, where limited access to prenatal care and diagnostic services exacerbates the impact. These conditions are a leading cause of infant mortality, long-term disability, and significant healthcare costs, making them a persistent global health concern.
In 2022, Brazil reported a notable increase in microcephaly cases linked to congenital Zika virus infection, particularly in the northeastern states. This outbreak highlighted the vulnerability of populations to emerging infectious causes of congenital abnormalities.

Claim

Congenital abnormalities are a profoundly serious problem that demands urgent global attention. These conditions not only cause immense suffering for affected children and their families but also place a significant burden on healthcare systems. Ignoring congenital abnormalities perpetuates preventable disability and death. It is unacceptable to overlook the need for better prevention, early detection, and treatment. Addressing congenital abnormalities must be a top priority for any society that values health, equity, and human dignity.

Counter-claim

It is misguided to consider congenital abnormalities an important problem. With modern medicine and technology, most cases are manageable or even preventable. The focus on congenital abnormalities diverts resources from more pressing health issues affecting larger populations. In reality, their overall impact on society is minimal compared to chronic diseases or infectious outbreaks. Prioritizing congenital abnormalities is an inefficient use of healthcare attention and funding.
