No horses on a New Jersey farm have shown symptoms of a deadly virus nearly a month after an infected horse visited for an exhibition, according to the New Jersey Department of Agriculture.

It's been 27 days since a Pennsylvania horse was somewhere in the Garden State — the agriculture department won't say where — for a weekend show before that horse was discovered to be carrying the EHV-1 virus.

The show horse and two others developed EHM, which is a neurological diseases associated with the virus, and were euthanized.

Pennsylvania officials confirmed on Christmas Eve the fate of three horses and officials in New Jersey began monitoring the farm where the sick horse had been on Dec.12. Generally, horses will show signs of the virus within a week of infection.

EHV, according to the Penn State Extension:

appears in horses worldwide

is highly contagious and lethal

is transmitted through horse-to-horse contact via the respiratory system, sometimes through human hands touching an infected horse and then a healthy horse or by contaminated equipment, feed or water buckets

usually manifests in either a respiratory or neurological condition

can lead to EHM, a fatal disease that attacks the lining of the blood vessels around the brain
