Understanding Foot and Mouth Disease
Foot and Mouth Disease (FMD) is a highly infectious and contagious viral disease that affects cloven-hoofed animals. It holds significant economic importance due to its potential for causing severe losses in the livestock industry.
Foot and mouth disease: A severe, highly contagious viral disease of cattle and swine, also affecting sheep, goats, deer, and other cloven-hoofed animals.
The Basics: What is Foot and Mouth Disease?
Foot and Mouth Disease, often abbreviated as FMD, is caused by a virus of the genus Aphthovirus, within the family Picornaviridae. The disease is characterised by the formation of blisters in the mouth and on the feet of affected animals.
Aphthovirus: A genus of viruses in the family Picornaviridae, known for causing Foot and Mouth Disease in animals.
The disease follows a predictable pattern of transmission with:
- Direct contact with infected animals
- Indirect contact through contaminated feed, water, bedding, equipment and vehicles
- Airborne spread
Historical Overview of Foot and Mouth Disease in the UK
The history of Foot and Mouth Disease in the UK traces back to the 19th century. Major outbreaks occurred in 1839, 1860, and most significantly, in 2001 when millions of animals had to be culled. This outbreak led to the creation of stringent disease control measures.

The Relevance of Foot and Mouth Disease in Adults
Adult animals are particularly at risk of Foot and Mouth Disease. The disease, while rarely fatal in adult animals, results in lowering of the milk yield, weight loss, and reduction in draught power.
In dairy cows, for instance, milk yields may drop almost to nothing, only to return gradually over several months or possibly not at all. Similarly, working animals may be affected to the point where their productivity greatly declines.
An example of the relevance of FMD in adults can be seen in a dairy farm setting. Let's assume a farm with 100 adult dairy cows. If all cows were to get infected with FMD, the farm could potentially lose virtually all its milk production, leading to vast economic loss.
Identifying Foot and Mouth Disease: Causes and Symptoms
Foot and Mouth Disease (FMD) manifests itself prominently amongst cloven-hoofed livestock. Its identifiable symptoms and highly contagious nature have significant implications for the agriculture industry.
Common Causes of Foot and Mouth Disease
FMD is caused by an Aphthovirus, a member of the Picornaviridae family. The introduction of this virus into an animal can occur through various means that include:
- Direct contact with infected animals. This is arguably the most common method of disease transmission. Ingress of the virus can happen through wounds or the mucous membranes in the mouth and nose.
- Indirect contact, which typically involves contamination from objects. These can include clothing, feed, equipment, vehicles, and even the hands of people handling infected animals.
- Airborne transmission. In conditions where there is a high density of animals, and especially with favourable wind conditions, the virus can spread via air for several kilometres.
A tell-tale characteristic of Foot and Mouth Disease which makes it such a prevalent threat is its persistence in the environment and resistance to varied conditions.
Recognising Foot and Mouth Disease Symptoms
Identifying FMD is primarily based on the recognition of its characteristic symptoms. Sudden fever and lameness are often the first signs. These symptoms usually sustain for a couple of days before blisters begin to develop on the feet and in the mouth.
The blisters eventually rupture, leading to excessive salivation and drooling. Affected animals might also exhibit other symptoms including:
- Depression and loss of appetite
- Reduced milk production in dairy animals
- Weight loss
- Heart problems in young animals
Early detection of these symptoms is paramount to managing FMD, ensuring rapid containment of the disease.
Foot and Mouth Disease Stages: From Exposure to Symptoms
Understanding the progression of Foot and Mouth Disease from exposure to symptoms is crucial in its control. There are usually three major stages:
1.
Incubation Period: Following exposure to the virus, animals undergo an incubation period that lasts typically between two and eight days. During this stage, no obvious symptoms manifest.
2.
Acute Phase: This phase is characterised by the sudden onset of high fever, often the first indication of infection. Other symptoms including depression, decreased appetite, and reduced milk yield in dairy animals follow.
3.
Vesicular Stage: After symptoms appear, vesicles (blisters) develop in the mouth and on the feet which are extremely painful, causing lameness.
The timely identification of these stages, along with diligent observation of the animals, provides the best chance to mitigate the impact of this disruptive disease.
Dealing with Foot and Mouth Disease: Treatment and Prevention
Unfortunately, FMD doesn't lend itself to any specific therapy or treatment options, as it is purely virally driven. There is a lack of antiviral treatments for the disease, which makes it challenging to manage once an outbreak has occurred. Management is primarily built on prevention, strict containment and control measures during outbreaks.
Foot and Mouth Disease Treatment: Methods and Effectiveness
To manage the impact of Foot and Mouth Disease, strategies focus largely on alleviating pain and distress in affected animals, and preventing the spread of the disease.
Anthelmintics can be used to remove internal parasites (this improves overall animal health making animals less susceptible to FMD), while non-steroidal anti-inflammatory drugs (NSAIDs) provide pain relief and reduce inflammation associated with the disease.
The effectiveness of such measures significantly depends on the stage at which they are administered. An early diagnosis improves the outcome by allowing effective symptom management and isolation.
However, the ultimate goal is to stop transmission between animals and to limit wildlife reservoirs. This involves the culling of infected and susceptible animals. And while culling is effective and often necessary from a population-wide perspective, it has ethical and economic implications due to the loss of livestock.
An additional strategy that is sometimes applied is vaccination. While not a treatment, vaccination serves as a form of control by promoting
herd immunity. Despite this, regular culling generally remains the preferred option in many jurisdictions due to difficulties related to serotype variation of the virus and the cost of the vaccines.
Preventing Foot and Mouth Disease: Practical Tips
Preventing FMD is the most effective way to control the disease.
Biosecurity measures are the cornerstone of prevention. This includes the enforcement of disinfection and cleaning protocols, strict regulation of animal movement, and surveillance.
Farmers play a significant role in preventing the spread of the disease by ensuring the following measures:
- Preventing access of farm animals to areas visited by wild cloven hoofed animals
- Prohibiting or severely reducing visitations to the farm, especially by those who may have been in contact with livestock
- Regularly disinfecting vehicles entering the farm
- Maintaining control over feed and water sources
- Notifying authorities immediately if signs of FMD are detected
Government-level control measures are also necessary for managing and preventing large scale outbreaks. These include setting up and enforcing quarantine zones, risk-based surveillance, livestock movement controls, and public education campaigns.
Coping with Foot and Mouth Disease in Adults
Foot and Mouth Disease in adult animals is usually not fatal but can be detrimental to their health and productivity. Management of adults with FMD requires both home care strategies and professional medical intervention.
Home Care Strategies for Adults with Foot and Mouth Disease
Adopting home care strategies can greatly aid in the recovery of adult animals affected by FMD. This does not mean a cure but constitutes supportive care intended to make the animal more comfortable, reduce stress, and prevent secondary infections.
Some effective home care strategies include:
- Providing a comfortable environment: Soft bedding can help ease discomfort from painful blisters on the feet.
- Nourishing diet: A high-energy diet can aid in maintaining the condition of the animal and facilitating recovery.
- Offering plenty of clean water: Dehydration can exacerbate the symptoms of FMD, making matters worse. Affected animals should have ready access to fresh, clean water at all times.
- Isolation: It is critical to separate affected animals from the rest of the herd as soon as FMD is suspected to prevent the spread of the disease.
Professional Medical Intervention for Adults with Foot and Mouth Disease
In addition to home care strategies, professional veterinary care is paramount in managing FMD in adult animals. The role of the veterinarian is crucial in diagnosing and notifying authorities of the disease, and providing supportive treatment strategies.
Medical interventions generally involve:
- Administering anti-inflammatory medication to reduce pain and inflammation
- Providing advice regarding nutrition and hydration
- Administering anthelmintic drugs to manage internal parasites
- Monitoring recovery and advising on when the animal can be reintroduced to the herd
Regular veterinary visits play a significant role in managing the health of an animal affected by FMD, from early diagnosis through to recovery and reintroduction to the herd.
Foot and Mouth Disease UK: Impact and Measures
In the UK, Foot and Mouth Disease (FMD) has devastating effects on the agricultural sector and the economy as a whole. Strict containment, eradication, and control measures have been adopted to manage FMD and reduce its implications.
How Foot and Mouth Disease Affects the UK
FMD has significant implications for the UK's agricultural sector, which relies heavily on livestock farming. Outbreaks disrupt trade, compromise food security, and negatively affect farm productivity. Economic costs of such episodes are substantial, involving loss of income from disease-inflicted livestock, costs of disease control, and trade sanctions from countries to which UK livestock products are exported.
Employment in the agricultural sector and related industries is also affected. Thousands of jobs are potentially at risk during and after major disease outbreaks. Added to these are impacts on wildlife populations, biodiversity, and the environment as well. As the virus that causes FMD can exist in wildlife, this presents an ongoing risk for livestock re-infection.
Trade Sanctions: Measures taken by one or more countries to limit trade with a country to pressure it into adhering to international law.
UK Measures Against Foot and Mouth Disease
Due to the severe implications of FMD, the UK government has implicated an array of strategies to control and prevent the disease. These include a robust regulatory framework, public education and awareness campaigns, and investment in disease research.
Education and Public Awareness of Foot and Mouth Disease in the UK
Educating the public, particularly those involved in handling livestock, is paramount to the effective control of FMD. The UK government regularly launches public awareness campaigns, sensitising the population about the disease, its risks, means of transmission, signs and symptoms, and reporting mechanisms if one suspects an animal is infected.
Many campaigns focus on empowering farmers to enact preventative measures to limit the spread of the disease. This includes the promotion of good farm
biosecurity, such as regular cleaning and disinfection, limiting and carefully managing visitors to the farm, and having a clear understanding of where feed and bedding comes from.
Moreover, the education and awareness campaigns also emphasise the importance of the responsible movement of livestock. This involves knowing the health status of animals before they are moved, isolating new animals, and reducing stress during transportation, as this may make animals more susceptible to disease.
Regulatory Framework for Foot and Mouth Disease in the UK
The UK government enforces a strict regulatory framework for the management of FMD. This includes regulations and guidelines for the rapid detection, reporting, and containment of the disease.
For example, the Animal Health Act 1981 provides the legal framework for dealing with FMD. It gives authorised officers the power to enter premises and carry out actions necessary for controlling the disease, such as valuing, slaughtering, or treating animals.
Other regulations under this Act require an immediate national standstill of livestock movement upon suspicion or confirmation of FMD. This plays a key role in limiting the spread of disease by halting the movement of potentially infected animals. Failure to adhere to these regulations can result in significant penalties.
The UK government also has a contingency plan in place for dealing with FMD outbreaks. This involves the activation of a National Disease Control Centre and Local Disease Control Centres to oversee the response, coordinate resources, and provide advice and support.
This comprehensive regulatory framework, along with a strong focus on public education and awareness, helps the UK to manage and control FMD effectively.
