DeCS - Health Sciences Descriptors is the trilingual vocabulary (English, Portuguese and Spanish) that represents the standard terminology used for both indexing and navigating the VHL information sources. The compatibility with the MeSH (Medical Subject Headings) terminology from NLM (National Library of Medicine) and the commitment with constant updating and translation to Portuguese and Spanish allowed the effective cooperation with the UMLS (Unified Medical Language System, NLM) project in the last years. The DeCS also contains the terminology of areas such as Public Health, Homeopathy, Science and Health, and Health Surveillance.
