BAKERSFIELD, Calif. -- The horse named Powered by Pep had just won his class at a competition in Bakersfield, Calif., when his owner, David Booth, noticed that the animal was not quite himself.
"A little slow-footed," the 22-year-old Acton rancher recalled.
Booth had Pep's temperature taken and soon discovered that his 7-year-old bay gelding had fallen victim to a dire outbreak of equine herpes virus-1, a highly contagious airborne virus that has killed or resulted in the euthanizing of at least seven horses this month and sown fear in equine circles across the Western states.
