Background In malaria-endemic countries in West Africa, sickle cell disease (SCD) contributes to childhood mortality. Historically, Liberia had regions wherein hemoglobin S and beta-thalassemia trait were mutually exclusive. Data on hemoglobinopathies in the Monrovia, the capital, are outdated and do not reflect urban migration. Updating the epidemiology of SCD is necessary to plan a public health and clinical agenda. Neither newborn screening (NBS) nor screening tools were available in-country. This pilot study aimed to determine the feasibility of NBS using a South-South partnership and define the incidence of sickle cell trait (SCT) and SCD in Monrovia. Procedure This descriptive epidemiologic feasibility study collected dried blood spots from 2785 consecutive newborns delivered at a hospital in Monrovia. Samples were analyzed by isoelectric focusing at a regional reference laboratory. Infants with SCD were referred for preventive care. Results SCT occurred in 10.31% of infants screened. SCD occurred in 33 infants screened [1.19% (95% CI: 0.79%–1.59%)](FS: 28/33, FSB: 2/33, FSA: 2/33, FSX 1/33). There were no infants with FSC phenotype observed. Non-sickling hemoglobin phenotypes ‘FC’ and ‘F’ were each present in 3 infants screened. Seventy-six percent of infants with SCD were brought to care, demonstrating the feasibility of our approach. Conclusions The incidence of SCD and other hemoglobinopathies remain high in Liberia. Additional studies are needed to clarify sickle genotypes and identify the contribution of silent beta-thalassemia alleles. By developing regional partnerships, countries similar to Liberia can acquire current data to inform NBS as an important public health initiative toward improving child health.
