In February 2019, an outbreak led to horse-racing meetings being cancelled in Britain between February 7 and February 12, after horses from an infected yard in Cheshire had raced the previous day. Following the first three cases at these stables, a further three cases were reported. It became known that there had recently been several outbreaks across Europe, and 7 in the UK since the start of 2019. In the latest incident, initially three vaccinated horses tested positive, resulting in the British Horseracing Authority (BHA) calling off races and putting in place "quarantine and biosecurity measures". The BHA stated "The full extent of potential exposure is unknown". The disease has been spreading across northern Europe, with the Republic of Ireland, France, Belgium and the Netherlands all affected.
