Objective: To assess the number of children born with microcephaly in the State of Paraíba, north-east Brazil.
Methods: We contacted 21 maternity centres belonging to a paediatric cardiology network, with access to information regarding more than 100 000 neonates born between 1 January 2012 and 31 December 2015. For 10% of these neonates, nurses were requested to retrieve head circumference measurements data from delivery-room books.
Problem: Providing health care for children with congenital heart diseases remains a major challenge in low- and middle-income countries.
Approach: In October 2011, the Government of Paraíba, Brazil, established a paediatric cardiology network in partnership with the nongovernmental organization Círculo do Coração. A cardiology team supervised all network activities, using the Internet to keep in contact with remote health facilities.
