Vesicular Stomatitis in Horses and Cattle: Symptoms, Treatment and Quarantine

By Dr Duncan Houston

A horse or cow with sudden drooling, raw mouth lesions or blisters around the coronary band should not be moved, entered into an event or treated casually as ordinary mouth trauma.

Vesicular stomatitis is usually self-limiting, but it is a reportable livestock disease and may look almost identical to foot-and-mouth disease in cattle, pigs and other cloven-hoofed animals. That means even a relatively bright animal with mild lesions can trigger an urgent regulatory investigation.

The immediate priorities are to stop animal movement, isolate the affected animal, use personal protective equipment and contact a veterinarian and the relevant animal-health authority.

Quick Answer

Vesicular stomatitis is a contagious viral disease that primarily affects horses, cattle and pigs. It causes painful blisters and erosions around the mouth, muzzle, teats, sheath and coronary bands, leading to salivation, reduced eating, lameness and lost milk production.

Any suspected case should be reported immediately. Do not move affected animals or their herd mates until the attending veterinarian and animal-health officials provide instructions. Treatment is supportive, while quarantine, vector control and biosecurity are used to limit spread. (APHIS)

Current U.S. Vesicular Stomatitis Situation

As of July 24, 2026, the ongoing U.S. outbreak had involved 37 affected premises across Arizona, Colorado and New Mexico. All clinically affected animals recorded in those premises were equids, although cattle, goats, sheep and pigs were present on some affected properties without showing clinical disease. Every confirmed case in the outbreak had been identified as vesicular stomatitis New Jersey virus. (APHIS)

The outbreak began in Arizona on October 31, 2025, expanded into Colorado in May 2026 and was confirmed in New Mexico later that month. Current premises remained quarantined in parts of Colorado and New Mexico at the time of the latest report. (APHIS)

This distinction matters. Cattle are susceptible to vesicular stomatitis, but the current U.S. outbreak had produced recognised clinical disease only in equids at the reporting date. Outbreak location, movement requirements and quarantined counties can change quickly, so livestock owners should check the current APHIS and State animal-health information before travelling, selling, exhibiting or exporting susceptible animals. (APHIS)

What Is Vesicular Stomatitis?

Vesicular stomatitis is caused by enveloped RNA viruses within the family Rhabdoviridae. The viruses of greatest relevance in North American outbreaks are vesicular stomatitis New Jersey virus and vesicular stomatitis Indiana virus.

The current U.S. outbreak involves the New Jersey virus, but the serotype cannot be determined from an animal’s species, lesion location or appearance. Laboratory testing is required. (CFSPH)

The disease is characterised by the formation of:

• Papules

• Fluid-filled vesicles

• Erosions

• Ulcers

• Crusting lesions

The vesicles may rupture within a short period, so the veterinarian may see a broad raw area, peeling epithelium or an ulcer rather than a neat, intact blister. (CFSPH)

Which Animals Can Be Infected?

Clinical disease most commonly affects:

• Horses

• Donkeys

• Mules

• Cattle

• Pigs

Clinical infection can also occur in:

• Llamas and alpacas

• Sheep

• Goats

Exposure has been identified in several wildlife species, although the natural reservoir that maintains the virus between outbreaks remains uncertain. (CFSPH)

Why Are Horses Important During an Investigation?

Foot-and-mouth disease affects cattle, pigs, sheep, goats and other cloven-hoofed animals, but it does not affect horses.

A vesicular outbreak involving horses may therefore make vesicular stomatitis more epidemiologically plausible. However, this must never be used as an excuse to diagnose cattle lesions by appearance alone. Any unexplained vesicular disease in cattle or pigs still requires immediate official investigation to exclude foot-and-mouth disease and other foreign animal diseases. (APHIS)

What Are the Signs in Horses?

Oral Lesions

The tongue is frequently one of the most severely affected areas.

Owners may notice:

• Excessive drooling

• Foamy saliva

• Reluctance to accept the bit

• Difficulty picking up or chewing feed

• Dropping hay or grain

• Reduced water intake

• Bad mouth odour

• Bleeding from ulcerated tissue

• Blisters or raw areas on the lips, gums, tongue or palate

The lesions are painful. A horse may remain alert and interested in food but repeatedly stop chewing because oral contact hurts.

Muzzle and Nasal Lesions

The muzzle and lips may become:

• Swollen

• Crusted

• Raw

• Weeping

• Painful to touch

Some horses develop crusted lesions around the nostrils or along mucocutaneous junctions without an obvious intact oral vesicle.

Coronary Band Lesions

Lesions around the coronary band may cause:

• Sudden lameness

• Reluctance to walk

• Swelling above the hoof

• Heat and pain around the coronary band

• Crusting or erosions at the hairline

• Rarely, significant hoof-wall damage

A horse presenting primarily for lameness may therefore have vesicular disease even when the owner has not noticed mouth lesions.

Less Common Sites

Lesions may also occur on:

• The sheath or prepuce

• The udder or teats

• The internal surface of the ear pinna

• Existing wounds

 

What Are the Signs in Cattle?

Cattle may develop many of the same oral and foot lesions as horses.

Possible signs include:

• Drooling

• Lip smacking

• Reluctance to eat

• Reduced rumination

• Blisters or erosions on the tongue

• Lesions on the dental pad, lips, gums or palate

• Muzzle lesions

• Coronary band inflammation

• Interdigital lesions

• Lameness

• Fever early in the disease

• Reduced milk production

• Weight loss

Some cattle may appear reasonably bright while eating poorly. A transient fever may have resolved by the time the animal is examined. (APHIS)

Teat and Udder Lesions

Dairy cattle may develop painful teat lesions that interfere with milking.

Complications may include:

• Reluctance to enter the parlour

• Kicking during milking

• Reduced milk let-down

• Secondary mastitis

• Contamination of milking equipment

• Increased labour and hygiene requirements

Affected cattle should be milked according to the veterinarian’s and animal-health officials’ instructions. Where milking continues, affected animals are generally handled last and equipment must be appropriately cleaned and disinfected. (CFSPH)

Does Vesicular Stomatitis Always Cause Fever?

No.

A transient fever may develop shortly before or at the same time as the first lesions. It may have disappeared by the time the animal is examined.

The absence of fever does not rule the disease out, particularly when salivation, oral erosions, teat lesions or coronary band lesions are present. (APHIS)

How Does Vesicular Stomatitis Spread?

Transmission is complex and varies between outbreaks.

Insect Transmission

Biting insects are considered the primary route by which vesicular stomatitis enters livestock populations.

Competent or suspected vectors include:

• Black flies

• Sand flies

• Culicoides biting midges

• Other biological or mechanical insect vectors

Outbreaks often occur during periods of increased insect activity and are frequently associated with warmer environments and waterways that support vector populations.

Direct Animal-to-Animal Spread

Once animals develop active lesions, virus may be present in:

• Vesicular fluid

• Saliva

• Material from ruptured lesions

• Contaminated oral or nasal secretions

Direct contact with lesions or secretions may transmit infection between susceptible animals.

Contaminated Equipment and Facilities

Potential fomites include:

• Feed troughs

• Water troughs

• Buckets

• Halters

• Bits

• Lead ropes

• Grooming tools

• Examination equipment

• Milking machines

• Boots

• Gloves

• Clothing

• Transport vehicles

Sharing feed, water and equipment between affected and unaffected animals can extend transmission within a property.

How Long Is the Incubation Period?

Clinical signs usually develop approximately 2 to 8 days after exposure, with many animals showing disease within three to five days.

This is one reason movement histories for the preceding week are important during an outbreak investigation. (APHIS)

How Worried Should You Be?

The disease has two separate levels of urgency:

1. The medical severity for the individual animal

2. The regulatory urgency for the property

An animal may have clinically mild disease while still representing an immediate reportable-disease concern.

Lower Clinical Severity, Immediate Reporting Required

The animal:

• Remains bright and responsive

• Has one or two small oral erosions

• Continues drinking

• Can eat softened feed

• Has no severe lameness

• Has no systemic deterioration

Action: Stop movement, isolate the animal and contact the veterinarian immediately. Mild disease does not remove the reporting requirement.

Moderate Clinical Concern

The animal has:

• Marked salivation

• Several painful mouth lesions

• Reduced feed intake

• Early dehydration

• Coronary band pain

• Moderate lameness

• Teat lesions

• Reduced milk production

Action: Obtain same-day veterinary examination and official reporting guidance. Analgesia, feeding modification and close hydration monitoring are likely to be needed.

High Clinical Concern

The animal has:

• Complete food refusal

• Reduced or absent water intake

• Severe lameness

• Extensive oral sloughing

• Secondary mastitis

• Significant weight loss

• Deep or infected lesions

• Persistent fever or depression

• Several affected animals on the property

Action: Urgent veterinary treatment and herd-level investigation are required.

Critical

The animal has:

• Severe dehydration

• Collapse or recumbency

• Inability to swallow

• Severe colic

• Minimal responsiveness

• Marked weakness

• Secondary septicaemia

• Major hoof separation

• Rapidly worsening mastitis

• Breathing difficulty unrelated to ordinary oral discomfort

Action: Seek emergency veterinary care immediately. Intensive supportive treatment or humane euthanasia may be required.

In horses, inadequate drinking can contribute to impaction colic, while administering non-steroidal anti-inflammatory medication to a dehydrated animal increases the risk of kidney injury.

What Else Can Look Like Vesicular Stomatitis?

Foot-and-Mouth Disease

In cattle and pigs, the oral, teat and foot lesions of vesicular stomatitis may be clinically indistinguishable from foot-and-mouth disease.

Foot-and-mouth disease has vastly greater animal-health and trade implications. It cannot be excluded by photographs, lesion location or the assumption that a property is low risk. Official laboratory investigation is required. (APHIS)

Traumatic Oral Injury

Possible causes include:

• Sharp feed

• Foreign material

• Abrasive bits

• Chemical burns

• Electrical injury

• Rope or halter trauma

• Tongue laceration

A clearly witnessed injury may explain one lesion, but it does not safely explain multiple animals developing similar erosions, salivation or lameness.

Caustic or Toxic Exposure

Irritating plants, chemicals or contaminated feed may produce:

• Oral ulceration

• Salivation

• Feed refusal

• Muzzle irritation

• gastrointestinal signs

Exposure history and lesion distribution may help, but official disease exclusion may still be necessary when lesions are genuinely vesicular.

Other Infectious Diseases in Cattle

Important considerations include:

• Bovine viral diarrhoea or mucosal disease

• Infectious bovine rhinotracheitis

• Bluetongue

• Malignant catarrhal fever

• Papular stomatitis

• Oral necrobacillosis

• Secondary bacterial stomatitis

These diseases may produce erosive or ulcerative lesions, but none should be diagnosed casually in place of a foreign-animal-disease investigation.

Teat and Hoof Disorders

Teat lesions, coronitis and lameness may also result from:

• Trauma

• Photosensitisation

• Chemical exposure

• Frostbite

• Bacterial mastitis

• Foot rot

• Digital dermatitis

• Laminitis

• Hoof abscesses

The combination of oral and foot or teat lesions is especially important.

When Is This a Reportable Emergency?

Treat the situation as an immediate regulatory emergency when you see:

• A fresh blister in a horse, cow or pig

• Several oral erosions without an obvious traumatic cause

• Sudden excessive salivation in multiple animals

• Oral lesions combined with coronary band or teat lesions

• Similar lesions in horses and cattle on the same property

• Vesicular disease in cattle or pigs

• A rapidly increasing number of affected animals

• Lesions in an animal recently moved through an affected region

• A suspected case during an active State or regional outbreak

In the United States, suspected vesicular disease should be reported to the State animal-health official and APHIS as directed. A foreign-animal-disease diagnostician or an authorised veterinarian may be sent to examine the animals and collect samples. (APHIS)

What To Do Right Now

1. Stop Animal Movement

Do not:

• Load animals for sale

• Attend a show, rodeo, race or fair

• Move herd mates to another property

• Sell or loan animals

• Share breeding animals

• Send animals to training facilities

• Move susceptible livestock without official permission

Movement may spread the disease and can compromise the investigation.

2. Contact the Veterinarian Immediately

Tell the veterinarian:

• Which species are affected

• Number of affected animals

• Date signs began

• Whether intact blisters are present

• Lesion locations

• Recent movements

• Recent visitors or events

• Other livestock species on the property

• Current regional outbreak information

• Whether anyone handling the animals has become unwell

The veterinarian should then contact the appropriate State or Federal animal-health official according to local requirements. (APHIS)

3. Isolate Affected Animals

Where it can be done safely:

• House affected animals separately.

• Prevent nose-to-nose contact.

• Use separate feed and water containers.

• Do not share tack, grooming tools or milking equipment.

• Assign dedicated carers where possible.

• Handle healthy animals before affected animals.

Isolation does not replace official quarantine, but it can reduce direct and fomite transmission within the property. (APHIS)

4. Wear Personal Protective Equipment

At minimum, people examining or caring for affected animals should use:

• Disposable gloves

• Protective clothing

• Eye protection during oral examination or sample collection

• Waterproof covering over open wounds

Wash hands thoroughly after handling the animal and change contaminated clothing or footwear before entering unaffected areas.

5. Do Not Rupture Blisters

Do not deliberately pop vesicles or peel loose epithelium.

This:

• Causes pain

• Releases virus-rich fluid

• Increases contamination

• May create deeper wounds

• Can complicate official sampling

Sample collection should be performed only under the direction of the veterinarian or animal-health authority.

6. Photograph Without Excessive Handling

Photographs can document:

• Lesion location

• Initial appearance

• Development over time

• Number of affected animals

Avoid repeatedly opening a painful mouth simply to obtain a better picture.

7. Provide Water and Palatable Feed

Until the veterinarian arrives, ensure water is immediately accessible.

Animals with oral lesions may tolerate:

• Softened grain

• Soaked pellets

• Soft hay cubes

• Palatable wet feed

• Less abrasive forage

Diet changes should be suitable for the species and production system. Avoid force-feeding an animal that cannot swallow safely. (APHIS)

8. Begin Vector Reduction

Practical measures may include:

• Housing animals in a barn or covered shelter during periods of high insect activity

• Using fans to reduce insect landing

• Applying species-appropriate, label-approved repellents

• Paying particular attention to the inner ear surfaces of horses where black flies may feed

• Cleaning pens and reducing organic debris

• Protecting feed and water from contamination

Vector control lowers risk but cannot guarantee prevention.

How Is Vesicular Stomatitis Diagnosed?

Clinical appearance alone cannot confirm the disease.

The diagnostic process normally involves:

1. Official notification

2. Epidemiological history

3. Examination of all susceptible species

4. Collection of fresh lesion samples

5. Laboratory testing for vesicular stomatitis

6. Exclusion of foot-and-mouth disease and other vesicular diseases where relevant

(APHIS)

Which Samples Are Collected?

The most useful samples may include:

• Vesicular fluid

• Swabs from fresh ruptured vesicles

• Epithelium over an intact vesicle

• Epithelial tags from a newly ruptured lesion

• Serum

• Paired serum samples where required

Lesions are painful, and sedation may be appropriate before extensive sampling. The laboratory or regulatory veterinarian should be contacted before samples are collected so that the correct materials, transport conditions and submission pathway are used. (CFSPH)

Which Tests Are Used?

Testing may include:

• Real-time reverse-transcription PCR

• Virus isolation

• Antigen-detection ELISA

• Virus-neutralisation testing

• Serology

• Paired antibody titres

Some assays can distinguish New Jersey and Indiana viruses. The testing pathway depends on the outbreak, species, sample type and laboratory authorisation. (WOAH)

How Is Vesicular Stomatitis Treated?

There is no specific antiviral treatment routinely used for affected livestock.

Treatment is aimed at:

• Controlling pain

• Maintaining food intake

• Maintaining hydration

• Preventing secondary complications

• Protecting damaged tissue

• Monitoring for worsening disease

(APHIS)

Pain Relief

The veterinarian may prescribe an appropriate anti-inflammatory or analgesic.

The medication plan must account for:

• Species

• Hydration

• Kidney function

• Pregnancy

• Competition or withdrawal rules

• Meat or milk withholding periods

• Other medication

A dehydrated horse or cow should not be given repeated anti-inflammatory medication without veterinary oversight.

Feeding Support

Animals with oral lesions may benefit from:

• Soaked or softened feed

• Less abrasive forage

• Easily accessible feed and water

• Several smaller feeding opportunities

• Monitoring of actual intake

The goal is to maintain nutrition without repeatedly traumatising the lesions. (APHIS)

Lesion Care

A veterinarian may recommend gentle cleaning with an appropriately diluted, non-irritating antiseptic where secondary contamination is a concern.

Avoid:

• Caustic chemicals

• Undiluted iodine

• Hydrogen peroxide

• Bleach

• Harsh scrubbing

• Unprescribed topical powders

• Tight hoof packing over wet lesions

The mouth, coronary band and teat tissue are already painful and vulnerable.

Antibiotics

Antibiotics do not treat vesicular stomatitis virus.

They should be considered only when there is evidence of secondary bacterial infection, such as:

• Mastitis

• Cellulitis

• Infected ulcers

• Deep tissue infection

• Secondary systemic bacterial illness

Routine preventive antibiotics are not justified solely because vesicular lesions are present.

How Long Does Recovery Take?

Most uncomplicated animals recover within approximately two to three weeks.

The visible blisters often rupture early, while healing of erosions and return to normal eating or performance may take longer. Recovery can be delayed by:

• Dehydration

• Secondary bacterial infection

• Severe oral tissue loss

• Mastitis

• Hoof involvement

• Poor nutrition

• Premature transport

• Continued insect exposure

(CFSPH)

A horse may remain unsuitable for work or transport even after fever has resolved. A cow may continue to show reduced milk production after the lesions begin healing.

How Does Quarantine Work?

During the current U.S. response, confirmed and presumptive positive premises are quarantined for at least 14 days from the onset of lesions in the last affected animal on the property.

Release is determined by State or Federal animal-health officials. Healing of lesions and the official outbreak protocol are important considerations. The owner should never calculate a release date independently or resume movement simply because the animal looks better. (APHIS)

Routine negative retesting is not stated as a universal requirement in the current APHIS release criteria. Additional testing, examination or certification may still be required by the responsible authority, destination State, event or importing country.

Does the Whole Property Get Quarantined?

Confirmed and presumptive premises may have all susceptible species placed under movement restrictions, not only the visibly affected animal.

This is because:

• Other animals may be incubating infection.

• Subclinical infection can occur.

• insects may move between groups.

• contaminated equipment may have been shared.

• new lesions may appear after the first case.

(APHIS)

Can People Catch Vesicular Stomatitis?

Yes, although recognised human disease is uncommon.

People may be exposed through:

• Vesicular fluid

• Saliva

• Direct contact with lesions

• Contaminated laboratory material

• Needlestick or accidental inoculation

• Possibly insect bites

Human illness is usually acute and self-limiting. Reported signs include:

• Fever

• Headache

• Muscle aches

• Fatigue

• Weakness

• Rare oral, lip or nasal vesicles

Symptoms commonly last approximately three to five days. More serious neurological disease is rare.

People who become unwell after handling a suspected or confirmed animal should contact a healthcare professional and explain the livestock exposure.

Immunocompromised people should avoid direct care of affected animals where another trained person is available.

How Can Vesicular Stomatitis Be Prevented?

No single measure provides complete protection because both insect-mediated and direct transmission may occur.

Reduce Insect Exposure

During regional outbreaks:

• Stable animals where practical during peak vector activity.

• Provide covered shelters.

• Use fans in barns.

• Apply approved insect repellents according to the label.

• Treat the inner ear surfaces of horses only with products labelled as safe for that use.

• Manage manure and organic waste.

• Work with local vector-control authorities where appropriate.

 

Quarantine New Arrivals

Keep new horses and susceptible livestock separate before introducing them to established groups.

During an outbreak, review:

• The animal’s recent travel history

• Counties and States visited

• Certificate-of-veterinary-inspection requirements

• Event-specific entry rules

• Current movement and export restrictions

(APHIS)

Inspect Animals Before Movement

Check:

• Lips

• Tongue

• Muzzle

• Coronary bands

• Teats

• Sheath

• Appetite

• Salivation

• Gait

Do not move an animal that has an unexplained lesion or recent contact with an affected premises.

Separate Equipment

Use dedicated:

• Halters

• Lead ropes

• Feed buckets

• Water buckets

• Grooming tools

• Milking equipment

• Examination equipment

• Foot-care tools

Disinfect equipment according to the veterinarian’s or animal-health authority’s instructions.

Handle Healthy Animals First

The preferred order is:

1. Healthy, unexposed animals

2. Exposed animals without lesions

3. Suspected or confirmed affected animals

Change gloves and protective clothing between groups.

Monitor Daily During Regional Outbreaks

Record:

• Rectal temperature where appropriate

• Appetite

• Salivation

• New mouth lesions

• Lameness

• Coronary band swelling

• Teat lesions

• Milk production

• Recent insect exposure

Early reporting helps contain movement before several animals become affected.

Is There a Vaccine?

There is currently no licensed commercially available vesicular stomatitis vaccine in the United States.

Experimental products have been developed, and vaccines may be available in certain endemic regions outside the United States, but U.S. prevention currently relies on surveillance, biosecurity, movement control and vector mitigation.

What Is the Prognosis?

Favourable Features

The outlook is generally good when:

• Lesions are limited

• Water intake remains adequate

• The animal continues eating softened feed

• Lameness is mild

• No secondary bacterial infection develops

• Hoof structures remain intact

• Supportive treatment begins early

More Guarded Features

Concern increases with:

• Complete food or water refusal

• Severe dehydration

• Extensive oral sloughing

• Impaction colic

• Mastitis

• Deep secondary infection

• Marked weight loss

• Major coronary band injury

• Hoof-wall separation

• Significant concurrent disease

Mortality directly attributable to vesicular stomatitis is rare, but secondary complications can become serious.

What Are the Economic Consequences?

Even when animals survive, outbreaks may cause:

• Reduced milk production

• Weight loss

• Lost training and competition time

• Event cancellations

• Movement restrictions

• Delayed sales

• Export restrictions

• Diagnostic and treatment costs

• Increased labour

• Vector-control expenses

• Biosecurity costs

• Disrupted breeding programmes

The regulatory and trade consequences may be far greater than the direct mortality caused by the virus. (APHIS)

Common Vesicular Stomatitis Mistakes

Waiting To See Whether More Animals Develop Lesions

The first suspicious animal is enough to justify reporting.

Moving the Animal Before the Vet Arrives

Movement can spread infection and complicate the official investigation.

Assuming It Cannot Be Foot-and-Mouth Disease

Vesicular lesions in cattle and pigs must be investigated officially.

Diagnosing It From a Photograph

Trauma, chemical injury, foot-and-mouth disease and several other disorders may look similar.

Popping the Blisters

Vesicular fluid may contain high concentrations of virus.

Examining the Mouth With Bare Hands

Vesicular stomatitis is zoonotic.

Giving Routine Antibiotics

Antibiotics do not treat the virus.

Using Harsh Antiseptics

Caustic treatment may deepen the lesions and reduce feeding further.

Assuming a Horse Is Safe To Travel Once the Lesions Improve

Movement remains controlled until officials release the premises.

Calculating the Quarantine Period Yourself

The responsible State or Federal authority determines release.

Ignoring Hydration

The lesion may look dramatic, but dehydration and loss of intake often determine how clinically unwell the animal becomes.

Frequently Asked Questions

Can vesicular stomatitis kill a horse or cow?

Death is uncommon. Severe dehydration, impaction colic, secondary infection, mastitis or major hoof complications can nevertheless become life-threatening.

Is vesicular stomatitis the same as foot-and-mouth disease?

No. They are caused by different viruses. Their lesions may look indistinguishable in cattle and pigs, which is why official laboratory testing is required. Horses do not develop foot-and-mouth disease.

How long is a property quarantined?

Under the current U.S. response, affected premises are quarantined for at least 14 days from lesion onset in the last affected animal. The final release decision belongs to State or Federal animal-health officials. (APHIS)

Can I continue riding or milking an affected animal?

Affected horses should not travel, compete or work while painful or quarantined. Dairy management should follow veterinary and regulatory instructions, with particular attention to teat pain, mastitis prevention, equipment hygiene and worker protection.

Can vesicular stomatitis spread through tack and buckets?

Yes. Saliva and lesion material may contaminate shared feed, water and equipment. Dedicated equipment and appropriate cleaning are essential.

Final Thoughts

Vesicular stomatitis is usually survivable, but it is never a disease to manage quietly without reporting.

The most important points are:

1. Vesicular stomatitis causes painful blisters, erosions and ulcers.

2. Intact blisters may have ruptured before the animal is examined.

3. Horses, cattle and pigs are the main livestock species affected.

4. The disease can spread through biting insects, direct contact and contaminated equipment.

5. Any suspected case should be reported immediately.

6. Vesicular lesions in cattle or pigs require urgent exclusion of foot-and-mouth disease.

7. Stop movement before waiting for laboratory confirmation.

8. Treatment is supportive and focuses on pain, hydration and nutrition.

9. Antibiotics are reserved for secondary bacterial infection.

10. Quarantine release is determined by animal-health officials.

11. Human infection is uncommon but possible.

12. Gloves, eye protection and careful hygiene reduce occupational risk.

13. No licensed commercial U.S. vaccine is currently available.

14. Most uncomplicated animals recover within two to three weeks.

15. The economic impact often comes from movement restrictions, production loss and trade disruption rather than mortality.

The mistake that matters most is treating the lesions as an ordinary mouth or hoof problem and moving the animal before the diagnosis is known. Stop movement, protect the people handling the animal and let the veterinarian and animal-health authority direct the response.

ASK A VET™ can help organise lesion photographs, temperature and appetite records, animal movements and quarantine documentation while owners and producers work directly with their attending veterinarian and animal-health officials. An animal with severe dehydration, inability to eat or drink, collapse, major hoof damage or rapidly worsening secondary infection still requires immediate hands-on veterinary care.
