A further clinical case of Influenza (flu) has been confirmed on a yard, in Gayton, adjacent to the yard where an outbreak was confirmed last week. We are still awaiting confirmation, probably early this week, as to the exact strain of flu virus we are dealing with.
Equine influenza has a maximum incubation period of 3 days and affected horses can then shed the virus for up to 11 days. It therefore makes sense that there should be no movement of horses on and off affected yards for at least 14 days after the onset of clinical signs in an affected individual.
It would appear vaccination does seem to be protecting individuals in the face of infection. Vaccinated horses can still become infected but often only show mild symptoms such as a serous nasal discharge rather than the typical signs of coughing, high temperature and profuse nasal discharge. Vaccinated horses can also shed the virus and can therefore spread the disease but usually for a shorter period of time. In order to offer maximum protection in the face of an outbreak, we recommend that your horse should have a flu booster vaccination if it has not received one within the last 6 months.
We will be able to offer further advice once we know which virus strain we are dealing with.
The following video shows a couple of individuals infected with flu.
