[EpiData: the natural heir to EpiInfo 6?].

EpiData is an epidemiological software developed by the EpiData Association (www.epidata.dk). Following the EpiInfo 6 philosophy, Epidata, offers all the advantages of EpiInfo 6: simplicity, applicability, few operation and communication system requirements, widening them with a clear focus on data quality and documentation plus the advantages that, for many users, has the Windows operating system. The aim of this Note is to introduce to potential users the strengths and limitations of EpiData, a software that can become in a short time the equivalent to what EpiInfo 6 was a few years ago.
