Overview

Disease profiles are based on systematic literature reviews. Note that the scientific evidence provided is based only on studies that met the inclusion criteria listed in the review protocol.

This disease profile explores the following aspects:

Geographic distribution

Based on official disease reports to the WOAH

Bluetongue disease - test is a disease listed in the World Organisation for Animal Health (WOAH) Terrestrial Animal Health Code and must be reported to the WOAH. The map to the right displays outbreak points reported to the WOAH early warning system since 2005.

As described in the WOAH Terrestrial Animal Health Code, the WOAH early warning system includes immediate notifications and follow-up reports on:

  • First occurrences of a listed disease,
  • Recurrence of an eradicated listed disease,
  • First occurrences of new strain of a pathogenic agent of a listed disease,
  • Recurrence of an eradicated strain,
  • Sudden and unexpected changes in the distribution or increase in incidence or virulence of, or morbidity or mortality caused by the pathogenic agent of a listed disease,
  • Occurrence of a listed disease in an unusual host species.

Countries are coloured according to the available information regarding their stable disease situation (disease situation legend). This information is provided by countries through the WOAH monitoring system, which is a different reporting channel.

The disease situations (country/region colours) are prioritised in the following order: Present, Suspected and Absent if more than one is present in a country during the filtered period.

Immediate notifications (points) and disease situation (country/region colours) are reported to the WOAH in different spatial and temporal scales, and therefore are displayed in the map as layers which can be filtered independently.
