I N BRIEF: EQUINE CORO­N­AVIRUS

EQUUS - - Eq Tack& Gear -

Def­i­ni­tion: gas­troin­testi­nal ill­ness caused by in­fec­tion with the equine coro­n­avirus (ECoV) Causes: The virus is thought to pass from horse to horse via the fecalote Signs: Fever of 101 to 1 lethargy and loss of ap­petite are the most com­mon signs; 10 to 15 per­cent of horses may have soft­ened stools or di­ar­rhea. In about 7 per­cent of cases, horses may ex­pe­ri­ence se­ri­ous com­pli­ca­tions in­clud­ing shock, or­gan fail­ure, sep­ticemia and neu­ro­log­i­cal signs. Di­ag­no­sis: Blood­work will show a drop in white blood cells con­sis­tent with vi­ral in­fec­tions. ECoV can be iden­ti­fied in fe­cal sam­ples. Treat­ment: Most horses re­cover fully within two to four days, or longer if they ex­pe­ri­enced loose stools. Sup­port­ive care, in­clud­ing flu­ids and anti-in­flam­ma­to­ries, may be help­ful. An­tibi­otics may be ad­min­is­tered to curb sec­ondary in­fec­tions in more se­ri­ous cases. Pre­ven­tion: Biose­cu­rity mea­sures to pre­vent healthy horses from com­ing into con­tact with those shed­ding the virus are nec­es­sary to limit the ex­tent of out­breaks.
