Listed Disease

Foot and mouth disease

Foot and mouth disease (FMD) is a severe, highly contagious viral disease of livestock that has a significant economic impact. The disease affects cattle, swine, sheep, goats and other cloven-hoofed ruminants. It is a transboundary animal disease (TAD) that deeply affect the production of livestock and disrupting regional and international trade in animals and animal products. The disease is estimated to circulate in 77% of the global livestock population, in Africa, the Middle East and Asia, as well as in a limited area of South America. Countries that are currently free of FMD without vaccination remain under constant threat of an incursion. Seventy-five percent of the costs attributed to FMD prevention and control are incurred by low income and lower-middle income countries. Africa and Eurasia are the regions which incur the largest costs, accounting for 50% and 33% of the total costs respectively. FMD is caused by an Aphthovirus of the family Picornaviridae, seven strains (A, O, C, SAT1, SAT2, SAT3, and Asia1) are endemic in different countries worldwide. Each strain requires a specific vaccine to provide immunity to a vaccinated animal. Its prevention is based on the presence of early detection and warning systems and the implementation of effective surveillance among other measures. FMD is the first disease for which WOAH established an official list of disease-free countries which can be officially recognised as free of the disease either in their entirety or in defined zones and compartments.

What is Foot and Mouth disease (FMD)?

Foot and mouth disease (FMD) is a severe, highly contagious viral disease of livestock that has a significant economic impact. The disease affects cattle, swine, sheep, goats and other cloven-hoofed ruminants.

Intensively reared animals are more susceptible to the disease than traditional breeds. The disease is rarely fatal in adult animals, but there is often high mortality in young animals due to myocarditis or, when the dam is infected by the disease, lack of milk.

FMD is characterised by fever and blister-like sores on the tongue and lips, in the mouth, on the teats and between the hooves. The disease causes severe production losses, and while the majority of affected animals recover, the disease often leaves them weakened and debilitated.

The organism which causes FMD is an aphthovirus of the family Picornaviridae. There are seven strains (A, O, C, SAT1, SAT2, SAT3, and Asia1) which are endemic in different countries worldwide. Each strain requires a specific vaccine to provide immunity to a vaccinated animal.

All seven of the serotypes have also been found in wildlife, although the latter does not play a significant role in the maintenance of the disease. To date, the only confirmed reservoir in wildlife is African buffalo Syncerus caffer).

FMD is an WOAH-listed disease and must be reported to the Organisation, as indicated in the Terrestrial Animal Health Code.

It was the first disease for which the World Organisation for Animal Health (WOAH, founded as OIE) established official status recognition. Members can also apply for official endorsement of their national control programmes.


Transmission and spread

FMD is found in all excretions and secretions from infected animals. Notably, these animals breathe out a large amount of aerosolised virus, which can infect other animals via the respiratory or oral routes.

The virus may be present in milk and semen for up to 4 days before the animal shows clinical signs of disease.

The significance of FMD is related to the ease with which the virus can spread through any or all of the following:

  • infected animals newly introduced into a herd (carrying virus in their saliva, milk, semen, etc.);
  • contaminated pens/buildings or contaminated animal transport vehicles;
  • contaminated materials such as hay, feed, water, milk or biologics;
  • contaminated clothing, footwear, or equipment;
  • virus-infected meat or other contaminated animal products (if fed to animals when raw or improperly cooked);
  • infected aerosols (spread of virus from an infected property via air currents).

Animals that have recovered from infection may sometimes carry the virus and initiate new outbreaks of the disease.


Public health risk

FMD is not readily transmissible to humans and is not a public health risk.


Clinical signs

The severity of clinical signs will depend on the strain of virus, the exposure dose, the age and species of animal and the host immunity. Morbidity can reach 100% in susceptible populations. Mortality is generally low in adult animals (1–5%), but higher in young calves, lambs and piglets (20% or higher). The incubation period is 2–14 days.

Clinical signs can range from mild or inapparent to severe: they are more severe in cattle and intensively reared pigs than in sheep and goats.

The typical clinical sign is the occurrence of blisters (or vesicles) on the nose, tongue or lips, inside the oral cavity, between the toes, above the hooves, on the teats and at pressure points on the skin. Ruptured blisters can result in extreme lameness and reluctance to move or eat. Usually, blisters heal within 7 days (sometimes longer), but complications, such as secondary bacterial infection of open blisters, can also occur.

Other frequent symptoms are fever, depression, hypersalivation, loss of appetite, weight loss, growth retardation and a drop in milk production, which can persist even after recovery. Chronically affected animals are reported to have an overall reduction of 80% in milk yield. The health of young calves, lambs, and piglets may be compromised by lack of milk if dams are infected.

Death can occur before development of blisters due to a multifocal myocarditis. Myositis may also occur in other sites.

More information on the disease can be found in the WOAH Technical Disease Card.


Diagnostic

The disease may be suspected based on clinical signs. However, FMD cannot be differentiated clinically from other vesicular diseases, such as swine vesicular disease, vesicular stomatitis and vesicular exanthema.

Confirmation of any suspected FMD case through laboratory tests is therefore a matter of urgency. Relevant tests are described in the Terrestrial Manual.


Prevention and control

The initial measures described in the Global Foot and Mouth disease control strategy are the presence of early detection and warning systems and the implementation of effective surveillance in accordance with the guidelines detailed in the Terrestrial Code. They help monitor the occurrence and prevalence of the disease and allow characterisation of FMD viruses.

The implementation of the FMD control strategy varies from country to country and depends on the epidemiological situation of the disease:

In general, it is essential for livestock owners and producers to maintain sound biosecurity practices to prevent the introduction and spread of the virus.

Measures that are recommended at the farm level include:

  • control over people’s access to livestock and equipment;
  • controlled introduction of new animals into existing herds;
  • regular cleaning and disinfection of livestock pens, buildings, vehicles and equipment;
  • monitoring and reporting of illness;
  • appropriate disposal of manure and dead carcasses.

Contingency planning for potential outbreaks will identify the elements included in a response effort to eradicate the disease, such as:

  • humane destruction of all infected, recovered and FMD-susceptible contact animals;
  • appropriate disposal of carcasses and all animal products;
  • surveillance and tracing of potentially infected or exposed livestock;
  • strict quarantine and controls on movement of livestock, equipment, vehicles, and;
  • thorough disinfection of premises and all infected materials (implements, cars, clothes, etc.).

Use of vaccination

Depending on the FMD situation, vaccination strategies can be designed to achieve mass coverage or be targeted to specific animal sub-populations or zones. Vaccination programmes carried out in a target population should meet several critical criteria, mainly:

  • coverage should be at least 80%;
  • campaigns should be completed in the shortest possible time;
  • vaccination should be scheduled to allow for interference from maternal immunity;
  • vaccines should be administered in the correct dose and by the correct route;

The vaccines used should meet WOAH standards of potency and safety, and the strain or strains in the vaccine must antigenically match those circulating in the field.

It is important to use inactivated virus vaccines, as inactivated virus does not have the ability to multiply in vaccinated animals. The use of live virus vaccines is not acceptable due to the danger of reversion to virulence

Vaccination can play a role in an effective control strategy for FMD, but the decision on whether or not to use vaccination lies with national authorities.

For more information on FMD vaccination, consult the related FAQ.


Geographical distribution

Foot and Mouth Disease is endemic in several parts of Asia and in most of Africa and the Middle East. In Latin America, the majority of countries apply zoning and are recognised as FMD-free, either with or without vaccination.

Australia, New Zealand, Indonesia, Central and North America, and continental Western Europe are currently free of FMD. However, FMD is a transboundary animal disease that can occur sporadically in any typically free area.

In accordance with the WOAH procedure for official recognition of disease status, this page provides access to the List of WOAH Members officially recognised free from foot and mouth disease (FMD) by the WOAH through the adoption of a resolution by the World Assembly of Delegates (Assembly) of the WOAH at the General Session in May every year.

A Member wishing to be officially recognised as disease-free by the WOAH should submit the questionnaire laid out in Chapter 1.6. of the Terrestrial Animal Health Code (Terrestrial Code) and comply with all requirements specified in the Terrestrial Code for FMD. The WOAH Scientific Commission for Animal Diseases (Scientific Commission) is responsible for undertaking, on behalf of the Assembly, the assessment of WOAH Members’ applications for their compliance with WOAH standards. The assessment carried out by the Scientific Commission is based on the recommendations formulated by a relevant ad hoc Group composed of world specialists in disease control.

Subsequent to a disease outbreak or when the Scientific Commission determines that the conditions are not met anymore to demonstrate compliance with the relevant requirements of the Terrestrial Code, a disease status may be suspended. The Scientific Commission may decide to reinstate the suspended status when a Member has submitted an application which fulfils all the requirements requested for the recovery of official disease status laid out in the relevant Chapters of the Terrestrial Code. The suspensions and recoveries of disease status are announced by the Director General of the WOAH in consultation with the Scientific Commission and the list of these is kept up to date until adoption of a new resolution by the Assembly the following May.

Suspension/reinstatement of status


Suspension of an “FMD-free country where vaccination is not practised” status

Guyana

Following the failure to submit the annual reconfirmation and the adequate documented evidence by the end of January 2024, according to Articles 1.6.2. and 8.8.2. of the Terrestrial Animal Health Code, the “FMD-free country where vaccination is not practised” status of Guyana as recognised by the WOAH World Assembly of Delegates in terms of Resolution No. 11 in May 2023 is suspended with effect from 20 February 2024.

Withdrawal of WOAH endorsement of ‘official control programme for FMD’

China (People’s Rep. of)

Following the assessment of China’s annual reconfirmation for its official control programme for FMD endorsed by WOAH, the Scientific Commission for Animal Diseases concluded that China no longer fulfils the requirements in Articles 1.6.2. and 8.8.39. of the Terrestrial Animal Health Code for a country having an endorsed official control programme for FMD. As a result, the endorsement of the “official control programme for FMD” for China, as recognised by the World Assembly of Delegates in terms of Resolution No. 12 in May 2023, was withdrawn with effect from 20 February 2024.

Establishment of a foot and mouth disease containment zone

Botswana

Following an immediate notification received from the Delegate of Botswana on an outbreak of FMD in Butale crush, Masungu, the “FMD-free zone where vaccination is not practised” status of Zone 6b of Botswana, consisting of part of Francistown as recognised by the World Assembly of Delegates in terms of Resolution No. 11 in May 2022, was suspended with effect from 18 August 2022.
The Delegate of Botswana submitted an application for the establishment of a containment zone within Zone 6b. The containment zone is located in Bisoli North, as described in the documentation submitted by the Delegate to WOAH on 28 November 2022 and 10 February 2023.
The Scientific Commission for Animal Diseases considered the application of Botswana in accordance with Resolution No. 15 of the 2020 Adapted Procedure and concluded that the containment zone was complaint with Articles 4.4.7. and 8.8.6. of the Terrestrial Animal Health Code.
In accordance with the Standard Operating Procedures on suspension, recovery or withdrawal of officially recognised animal health status, the “FMD-free zone where vaccination is not practised” status is re-instated with effect from 03 March 2023, with the exception of the territory of the containment zone.


Suspension of an “FMD free zone where vaccination is not practised” status

Kazakhstan

Following a letter received from the Delegate of Kazakhstan informing WOAH about the start of vaccination against FMD, the “FMD free zone where vaccination is not practised” status of Zone 1 (consisting of West Kazakhstan, Atyrau, Mangystau and south-western part of Aktobe region), Zone 2 (including north-eastern part of Aktobe region, southern part of Kostanay region and western part of Karaganda region), Zone 3 (including northern and central parts of Kostanay region, western parts of North Kazakhstan and Akmola regions) and Zone 4 (including central and eastern parts of North Kazakhstan region and northern parts of Akmola and Pavlodar regions) as recognised by the World Assembly of Delegates in terms of Resolution No. 11 in May 2022, is suspended with effect from 9 June 2022.


Suspension of an “FMD free country where vaccination is not practised” status

Indonesia

Following an immediate notification received from the OIE Delegate of Indonesia on an outbreak of FMD in Mojokerto, Sidoarjo, Gresik, and Lamongan districts in the province of Jawa Timur, the “FMD free country where vaccination is not practised” status of Indonesia as recognised by the World Assembly of Delegates in terms of Resolution No. 13 in May 2021, is suspended with effect from 12 April 2022.
