Abstract
Late human immunodeficiency virus (HIV) diagnosis is an important cause of HIV-related morbidity and mortality in infants and children. Methods: This retrospective cohort study of HIV-infected children diagnosed in Sergipe, in northeastern Brazil, between 2002 and 2011 aimed to determine the prevalence of and risk factors for late HIV diagnosis. Results: Of 55 infants and children with confirmed infection, 42 (76.5%) were diagnosed at >= 12 months old. No antiretroviral prophylaxis during delivery (OR 5.48, 95% CI 1.11-32.34) was associated with late diagnosis. Conclusions: More than 75% of cases were diagnosed late. Efforts are needed to improve early HIV diagnosis in infants.
