how do we control disease
How do we control disease?
  • Vaccinations
  • Farm Management
how it works
How it Works
  • Infection Control Plan
    • Avoid or minimize exposure
    • Optimize resistance
      • Vaccination
      • Optimize overall health care
      • Areas to consider
        • Nutrition and training/exercise schedule
        • Ventilation and airflow in stabling area
        • Insect control
      • Other
        • Example: “normal” gastrointestinal flora
risk of disease
Risk of Disease
  • Varies by type of horse population!
  • Some horses predisposed to disease if exposed:
    • Foals, old horses
    • Problems with digestive function
    • Drug treatments
  • Situations can increase risk of exposure
    • Commingling with other horses
    • Exposure to insects
before we talk control
Before we talk “control…”
  • Do you recognize a sick vs. a healthy horse?
controlling infectious diseases
Controlling Infectious Diseases
  • Infection Control Plan
  • Avoid or minimize exposure
  • Optimize resistance
    • Vaccination
    • Optimize overall health care
    • Other
avoiding minimizing exposure
Avoiding/Minimizing Exposure
  • How are diseases transmitted?
    • Aerosol
    • Oral
    • Direct Contact
    • Fomites
    • Vector
    • Zoonotic
  • Limiting exposure must address all methods of diseasetransmission!
things to consider hygiene and sanitation
Things to Consider – Hygiene and Sanitation

Where would you rather your horse be?

equine herpes virus
Equine Herpes Virus
  • “Rhino”
  • 9 documented strains
    • 5 affect domestic horses
    • EHV-1 and EHV-4 are most common and pathogenic
  • Clinical Signs:
    • Fever!
    • Malaise
    • Respiratory
    • Abortion
    • Neurologic
equine infectious anemia
Equine Infectious Anemia
  • “Swam Fever”
  • Horses = natural host
  • Clinical Signs:
    • Severe depression
    • Weakness
    • Sudden onset of high fever
    • Anemia!
  • No treatment available!
  • Detection = Coggins Test
equine viral arteritis
Equine Viral Arteritis
  • EVA
  • Clinical Signs:
    • Respiratory Infection
    • Abortion
    • Subfertility (stallions)
    • Limb and Scrotal Edema
    • Skin reaction
influenza
Influenza
  • Clinical Signs:
    • Harsh, dry cough
    • Loss of appetite
    • Depression
    • Watery nasal discharge
  • Can lead to pneumonia
eastern western venezuelan equine encephalomyeltis
Eastern, Western, Venezuelan Equine Encephalomyeltis
  • ZOONOTIC DISEASES!
  • High fatality rates
    • Eastern > Venezuelan > Western
  • Neurological Signs
vesicular stomatitis
Vesicular Stomatitis
  • Can be transmitted between cattle/pigs and horses
  • Clinical Signs:
    • Ulceration of mucosa and coronary band
    • Crusting lesions of sheath, abdomen
  • Reportable Disease
rabies
Rabies
  • ZOONOTIC DISEASE
  • Raccoon strain most common here
  • Neurological symptoms
    • Behavioral changes are most common
    • Time to clinical signs varies
    • No treatment
streptococcus equi
Streptococcus Equi
  • “Strangles”
  • Clinical Signs:
    • High Fever
    • Nasal Discharge
    • Abscessed Lymph nodes
    • “Silent Carrier” status
  • High morbidity, low mortality
salmonellosis
Salmonellosis
  • ZOONOTIC DISEASE!
  • Clinical Signs:
    • Colitis
    • Diarrhea
  • Highly contagious bacterial infection
contagious equine metritis
Contagious Equine Metritis
  • Clinical Signs:
    • Uterine infection
    • Failure to conceive
  • Strict importation controls
rhodococcus equi
RhodococcusEqui
  • Leading cause of foal pneumonia
    • Foals under 6 months of age most susceptible
    • High (28%) mortality rate
vaccinations
Vaccinations
  • Purpose  Acquired Immunity to disease
  • Initial vaccination
    • Boosters for unvaccinated animals – 3-6 weeks apart (up to 3, depending on vaccine)
  • Annual or semi-annual boosters
  • Routes of Administration
  • Consult with vet
  • Different vaccines for different “types” of horses!
    • Broodmares vs. performance vs. “home-bound”
routes of administration
Routes of Administration

Intramuscular (IM)

Intranasal (IN)

what are your options
What are your options?
  • Establish a Biosecurity Plan
    • Not as easy as vaccination
    • Risk aversion of the operation or horse owner?
  • All will come at some cost!
communication with staff owners and visitors
Communication with staff, owners and visitors!
  • Make sure they know the rules!
  • Language barriers?
  • Signage
visitors and employees
Visitors and employees?
  • Ask! Especially if there is a current disease outbreak in the area
  • Use good hygiene methods
  • Have a plan in case of outbreak
traffic patterns
Traffic patterns
  • People, animals, vehicles
    • Farm personnel
    • Veterinarians
    • Farriers
    • Visitors
    • Horse owners (boarders)
  • Wheel barrows, trucks, trailers, tractors, 4-wheelers, etc.
facility design
Facility Design
  • Think about infection control before you build
    • Alleyways
    • High traffic areas
    • Treatment areas (stocks, wash stall, etc.)
  • Ease of cleaning
  • Can it be isolated?
facilities
Facilities
  • Separated from other horses for (ideally) a minimum of 3 weeks
  • How far apart?
    • Distances diseases travel not established
    • “35 feet” rule for neurological herpes virus?
  • Management
    • Separate equipment
    • Do new horses last
what if facilities or schedules don t allow isolation
What if facilities or schedules don’t allow isolation?
  • Group horses according to use/exposure potential
  • Commingled horses are of equal status – exposure WILL happen between them
options for managing risk posed by horse contact
Options for managing risk posed by horse contact
  • Establish health requirements
    • Visiting horses
    • New arrivals
    • Horses returning after an event
  • Segregation by risk level
  • Isolation/monitoring of new arrivals
  • Monitoring for illness + plan of action
examples of health requirements
Examples of Health Requirements
  • Certificate of veterinary inspection (health certificate)
    • Timing of exam vs. arrival of horse?
  • Ask about past medical history
    • Illness in this horse or others it has been around
  • Examine horse when it arrives
  • Test for infection
    • Coggins test
    • Others (i.e., screening for strangles)
isolation of new arrivals
Isolation of New Arrivals
  • Adequate facilities?
  • Adequate equipment?
  • Enough personnel?
  • All must be present to ensure good infection control!
early detection is key
Early detection is key
  • Determine cause of disease
    • Allows you to develop a control plan
  • Isolate ill horse(s) at first sign of disease
  • DO NOT MOVE EXPOSED HORSES
    • Until you have determinedthey don’t pose a risk to unexposed horses
    • Monitor exposed horses for illness
