World Birth Defects Day is observed to raise awareness about conditions that remain one of the leading causes of neonatal mortality and childhood disability in the Americas. Despite many being preventable or treatable, thousands of families each year face diagnoses that require specialized care, long-term follow-up, and comprehensive support. Under the theme “Every journey matters,” this year’s observance highlights not only the impact on affected children but also on their families and communities, emphasizing the need for stronger prevention efforts and timely access to quality health services.
Although neonatal mortality in the region has declined significantly over the past two decades, deaths due to congenital malformations have not decreased at the same pace. More than 20,000 newborns die annually from birth defects in the Americas, and nearly 22% of deaths in the first month of life are linked to these conditions. As progress is made in controlling infections and childbirth complications, birth defects account for a growing proportion of neonatal deaths.
This gap is partly due to the complexity of preventing and addressing birth defects. While other causes of neonatal mortality have been reduced through relatively simple and cost-effective interventions, tackling congenital anomalies requires sustained action before pregnancy, during gestation, and after birth. It involves integrated measures related to health, nutrition, environmental protection, and access to specialized services. Persistent inequalities in prevention, early diagnosis, and care, along with weaknesses in surveillance systems, further complicate effective responses.
Birth defects in the region stem from multiple causes, including genetic factors, nutritional deficiencies such as lack of folic acid, infections during pregnancy like rubella and Zika, and environmental exposures. While not all cases are preventable, many can be avoided or mitigated through public health interventions such as proper nutrition, vaccination, infection prevention, and strengthened preconception and prenatal care.
Among the most impactful public health measures are food fortification with folic acid, which significantly reduces central nervous system defects, and vaccination against rubella to prevent congenital rubella syndrome. Strong epidemiological surveillance, screening programs, and registry systems are also essential for reducing the burden of these conditions and improving health outcomes.
To support evidence-based decision-making, regional efforts have focused on strengthening surveillance and data systems. Consolidated data from national programs help identify trends, close gaps, and guide resource allocation. Timely and reliable information enables better planning of services, particularly for conditions that can be treated after birth, such as certain congenital heart defects and metabolic disorders.
Technical cooperation, training, and policy development also play a key role in improving prevention, early detection, and comprehensive care. Many effective actions can be implemented through primary health care, especially in preconception and prenatal services. A comprehensive approach that combines prevention, timely diagnosis, specialized treatment, and long-term follow-up—grounded in equity and free from stigma—is critical to supporting affected families.
The Zika epidemic of 2016–2017 underscored the importance of coordinated surveillance systems capable of detecting unusual increases in congenital anomalies. It also highlighted the need to integrate epidemiological monitoring with clinical care and long-term follow-up, reinforcing a life-course approach and comprehensive response to infectious disease-related birth defects.
Significant challenges remain in expanding neonatal screening coverage and ensuring equitable access to early diagnosis and specialized services across Latin America and the Caribbean. Social, economic, and geographic disparities continue to affect timely care. Strengthening prevention before and during pregnancy, addressing environmental risks, and ensuring effective referral networks are essential steps toward reducing the impact of conditions such as congenital heart defects and spina bifida.
The central message of this year’s observance is that every child and every family deserves support, respect, and access to quality health services. Advancing prevention, early detection, and comprehensive care through strong public policies and resilient health systems is vital. Behind every diagnosis is a story that calls for sustained commitment, equity, and compassionate support.
