The Maryland Department of Agriculture has reported three farms in Maryland were put under an EHV-1 "hold" on March 1, 2018, as they had horses that had been at the EHV-1 premises in Virginia the weekend of March 24 and 25.
One farm in Montgomery County reported a horse with a fever that did test EHV-1 positive on blood (but not on the nasal swab) on March 5.
A horse was reported with a fever on a farm in Calvert County on March 7, but it tested negative on blood and swab on March 8.
The third farm in St. Mary's County reported that all horses remain afebrile.
All three farms remain under hold orders. No horses have displayed any neurologic signs.
