The dates between brackets are the date of start and the date of end of validity of the record “disease”. When relevant, these dates indicate either when a disease has become an WOAH-listed disease or has stopped being an WOAH-listed disease, either when a change in the reporting of the disease according to the WOAH Codes has occurred. When no date is specified, this means that the record “disease” is valid in WAHIS database from 2005 up to date. For example, “Camelpox (2006 -)” means that camelpox was listed in 2006 and continue to be an WOAH-listed disease up to date; “Vesicular stomatitis (-2014)” means that vesicular stomatitis is not an WOAH-listed disease any more since 2014.
It is worth to specially mention “Highly path. avian influenza (-2017)” and “Highly pathogenic influenza A viruses (infection with) (non-poultry including wild birds) (2017-)”. For this particular disease, “2017” is the year when a change in reporting was introduced by the Terrestrial Code, namely, from 2017 this disease is reported in poultry and non-poultry separately.
