Equine Influenza (EI)

RESPE are calling for vigilance following the influenza alerts from 14 December 2018 to 2 January 2019. To date, four influenza outbreaks have been confirmed in France by LABEO Frank Duncombe. An investigation is underway to explore a possible epidemiological link between the last three outbreaks (competition in a neighbouring foreign country and importation of an unvaccinated animal from the same country).

On 14 December 2018, the first influenza outbreak was identified in Paris (ICC Dec 18 #06). In this equestrian centre of about 100 horses, nine of them presented with coughing, nasal discharge and pyrexia. They were all or part vaccinated. Health measures were put in place as soon as the clinical signs appeared, in particular concerning the movements that have been suspended since the confirmation of the first case.

The second outbreak is in the Pas-de-Calais (ICC Dec 18 #08). A four-year-old Selle Fran├žais Sports Horse was diagnosed positive for flu on 21 December 2018. This horse was not vaccinated. To date: 14 out of 50 horses show symptoms of coughing and pyrexia. Health measures have also been taken in this outbreak at the onset of symptoms and have been strengthened since the confirmation of the cases.

A third outbreak in the Ardennes was confirmed on 28 December 2018 (ICC Dec 18 #10). They are all up to date on their vaccinations and the clinical signs started after the introduction of an unvaccinated horse from Belgium. To date, the RESPE expects additional information on the characteristics of this outbreak. Health measures have been put in place, including stopping movements since confirmation.

The last outbreak is in Nord (ICC Jan 19 #01). There are 100 vaccinated horses at this premises, of which six horses are declared symptomatic with a variable clinical picture according to the individuals. Among them, a horse was diagnosed positive for flu on 2 January 2019. This horse had recently travelled to Belgium for participation in a competition.
