Transmission via contaminated hands, water and feed is also possible (in principle, like human flu). Virus shedding can occur from both sick and clinically unaffected horses. An outbreak of clinical disease without the prior introduction of new animals into a herd is therefore possible. The virus can be shed for approximately 2-3 weeks after infection or reactivation. In horses that develop an EHV-related CNS form, the virus may be shed for an even longer period. The virus can remain stable in the environment for up to 14 days.<br>The CNS form occurs both sporadically and epizoatically. Most cases are observed in late winter, spring, and early summer. Why and when the disease leads to CNS symptoms is not yet fully understood. The proportion of horses that develop the CNS form during an EHV-1 outbreak varies greatly, but is approximately 10 %.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Symptoms<\/h3>\n\n\n\n<p>The clinical symptoms appear approximately 6 to 10 days after infection or after reactivation of the virus in latent carriers, but can also become visible later.<br>The manifestation of the symptoms varies greatly and depends on the number, size and location of the spinal cord lesions. They often appear without accompanying clinical symptoms.&nbsp;<strong>Fever can be observed but is often not detected unless horses are regularly monitored.<\/strong>&nbsp;Most horses are within the normal range, some may have a low temperature.<br>Affected horses usually show suddenly appearing, symmetrical or mildly asymmetrical ataxia of varying severity, weakness of the fore and hind limbs, and reduced tail and anal tone. The hind limbs are generally more severely and earlier affected than the fore limbs during the course of the disease. In mild cases, reluctance to move, awkwardness, stumbling, a wobbly gait, and toe dragging can be observed. Urinary incontinence and difficulty urinating are also often observed. In severe cases, profound limb weakness and staggering of the hind limbs occur, followed by complete paralysis of the hind limbs (with a dog-sitting posture), paralysis of all 4 limbs, and recumbency of the horses.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Diagnosis of EHV<\/h3>\n\n\n\n<p>The diagnosis of EHV can be made by serological testing of blood. It is not possible to differentiate between antibodies from vaccination and antibodies caused by infection.<br>A positive result from a single sample only allows the conclusion that the horse has had contact with the virus in the past and\/or has been vaccinated.<br>For a definitive diagnosis, a second sample needs to be tested after 2-3 weeks, which will show if the antibody level has changed, indicating the horse has encountered the virus.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Vaccination against EHV infection<\/h3>\n\n\n\n<p>A\u00a0<strong>regular<\/strong>\u00a0and\u00a0<strong>consistent<\/strong>\u00a0<a href=\"https:\/\/pferdepraxis-roedig.de\/en\/vaccination-in-horses\/\">Vaccination programme\u00a0<\/a><strong>of the entire stock<\/strong>\u00a0It is recommended to build up the highest possible herd immunity.<br>However, vaccination does not always protect against clinical symptoms (infections) or virus-carrier status (horses that are not ill but shed the virus). From today's perspective, vaccination does not directly protect against EHV-related CNS disease, but vaccinated horses show shorter periods of virus shedding (lower risk of virus transmission).<\/p>\n\n\n\n<p>An emergency vaccination during EHV outbreaks is controversial and many experts and professors advise against it. In the worst-case scenario, a vaccination during an ongoing EHV outbreak on the premises could weaken an individual horse's immune system to such an extent that the EHV virus actually breaks out.<br>If vaccination were to happen now, immunity in the horse against EHV would only be expected after the second vaccination (i.e., complete basic immunisation after 4-6 weeks).<\/p>\n\n\n\n<p>Further information and source:&nbsp;<a href=\"http:\/\/www.idexx.de\/tiergesundheit\/laboratory\/pdfs\/archiv_pdfs\/diagnostic_update_2010\/du_equine_herpesvirus_0810.pdf\">Idexx Laboratories<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Equines Herpesvirus 1 und 4 (EHV 1 und 4) Drei Hauptsymptome werden im Zusammenhang mit beiden Viren beschrieben: Rhinopneumonitis eine Art Grippe), Myeloenzephalopathie (Zentralnerv\u00f6se Symptome- &gt; ZNS-Form)(beide EHV1) und (Sp\u00e4t-)Abort (Verfohlen)(EHV4), wobei die ZNS-Form die unter den Pferdebesitzern gef\u00fcrchtetste Form [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-117","page","type-page","status-publish","hentry","clearfix"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Infektionskrankheiten - Equines Herpesvirus - Tier\u00e4rztliche Praxis f\u00fcr Pferde - Dr. Nina R\u00f6dig - Fachtier\u00e4rztin<\/title>\n<meta name=\"description\" content=\"Equines Herpesvirus 1 und 4 (EHV 1 und 4)\" \/>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/pferdepraxis-roedig.de\/en\/equine-herpesvirus-infectious-diseases\/\" \/>\n<meta property=\"og:locale\" content=\"en_GB\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Infektionskrankheiten - Equines Herpesvirus - Tier\u00e4rztliche Praxis f\u00fcr Pferde - Dr. Nina R\u00f6dig - Fachtier\u00e4rztin\" \/>\n<meta property=\"og:description\" content=\"Equines Herpesvirus 1 und 4 (EHV 1 und 4)\" \/>\n<meta property=\"og:url\" content=\"https:\/\/pferdepraxis-roedig.de\/en\/equine-herpesvirus-infectious-diseases\/\" \/>\n<meta property=\"og:site_name\" content=\"Tier\u00e4rztliche Praxis f\u00fcr Pferde - Dr. Nina R\u00f6dig - Fachtier\u00e4rztin\" \/>\n<meta property=\"article:publisher\" content=\"https:\/\/www.facebook.com\/tierarztpraxisroedig\/\" \/>\n<meta property=\"article:modified_time\" content=\"2022-01-17T14:22:48+00:00\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<meta name=\"twitter:label1\" content=\"Estimated reading time\" \/>\n\t<meta name=\"twitter:data1\" content=\"4 minutes\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\\\/\\\/schema.org\",\"@graph\":[{\"@type\":\"WebPage\",\"@id\":\"https:\\\/\\\/pferdepraxis-roedig.de\\\/infektionskrankheiten-equines-herpesvirus\",\"url\":\"https:\\\/\\\/pferdepraxis-roedig.de\\\/infektionskrankheiten-equines-herpesvirus\",\"name\":\"Infektionskrankheiten - Equines Herpesvirus - Tier\u00e4rztliche Praxis f\u00fcr Pferde - Dr. Nina R\u00f6dig - Fachtier\u00e4rztin\",\"isPartOf\":{\"@id\":\"https:\\\/\\\/pferdepraxis-roedig.de\\\/#website\"},\"datePublished\":\"2020-11-01T14:31:08+00:00\",\"dateModified\":\"2022-01-17T14:22:48+00:00\",\"description\":\"Equines Herpesvirus 1 und 4 (EHV 1 und 4)\",\"breadcrumb\":{\"@id\":\"https:\\\/\\\/pferdepraxis-roedig.de\\\/infektionskrankheiten-equines-herpesvirus#breadcrumb\"},\"inLanguage\":\"en-GB\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\\\/\\\/pferdepraxis-roedig.de\\\/infektionskrankheiten-equines-herpesvirus\"]}]},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\\\/\\\/pferdepraxis-roedig.de\\\/infektionskrankheiten-equines-herpesvirus#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"name\":\"Startseite\",\"item\":\"https:\\\/\\\/pferdepraxis-roedig.de\\\/\"},{\"@type\":\"ListItem\",\"position\":2,\"name\":\"Infektionskrankheiten &#8211; Equines Herpesvirus\"}]},{\"@type\":\"WebSite\",\"@id\":\"https:\\\/\\\/pferdepraxis-roedig.de\\\/#website\",\"url\":\"https:\\\/\\\/pferdepraxis-roedig.de\\\/\",\"name\":\"Tier\u00e4rztliche Praxis f\u00fcr Pferde - Dr. Nina R\u00f6dig\",\"description\":\"Orthop\u00e4die mit Ultraschall, dig.
