4.7 Expected outcomes

in accordance with the Terrestrial Code, 2013 (Boxes 1, 2 and 3).

BOX 1 FMD case (OIE Terrestrial Code, Chapter 8.6.1.)

A case is an animal infected with FMD virus.

BOX 2 FMDV infection (OIE Terrestrial Code, Chapter 8.6.1.)

1. FMD virus (FMDV) has been isolated and identified as such from an animal or a product derived from that animal; or 2. Viral antigen or viral ribonucleic acid (RNA) specific to one or more of the serotypes of FMDV has been identified in samples from one or more animals, whether showing clinical signs consistent with FMD or not, or epidemiologically linked to a confirmed or suspected outbreak of FMD, or giving cause for suspicion of previous association or contact with FMDV; or 3. Antibodies to structural or non-structural proteins of FMDV that are not a consequence of vaccination, have been identified in one or more animals showing clinical signs consistent with FMD, or epidemiologically linked to a confirmed case?

BOX 3 FMDV circulation (OIE Terrestrial Code, Chapter 8.6.42.)

From the OIE Terrestrial Code, virus circulation means transmission of FMDV as demonstrated by clinical signs, serological evidence or virus isolation.

The expected outcome of the control programmes listed under A to D in Table 4.1 in the Terrestrial Code are defined in terms of one or more of the following:

1. The incidence of disease or FMDV infection is reduced.

2. The incidence of disease or FMDV infection is below a defined target value.

3. The incidence of disease or FMDV infection is shown to be absent.

The general approach to monitoring a control programme will make extensive use of epidemiological field observational studies that are not considered in the present guidelines. How to design such studies can be found in many epidemiology textbooks.
