CWD (Level 2)

In monitoring of CWD, two rows will be created for each positive or inconclusive/pending animal (i.e. one row per sample), with the field Part* prepopulated based on the assumption that samples from both obex and the retropharyngeal lymph node have been collected and tested. In order to complete Sample Level Data (level 2) for CWD, reporting countries need to populate a number of fields, as follows:

• Data check: not editable, contains error/warning messages which guide the user during the editing

• Sample/case assessment~: this field represents the final status of the CWD case, according to the testing protocol, after conducting all the necessary analytical tests. In the case of CWD, the sample/case assessment should be the same for the two different samples of the same animal. The available options are:

  • BSE-not excluded (i.e. BSE like)
  • CWD
  • Inconclusive case
  • Negative sample
  • Pending (available since TSE tool version 2.0.0)

  Since v2.0.0, if the final status of the sample is not yet available, there is the option to select "Pending" until the final result is available. This option is only supposed to be used in exceptional circumstances. A report will not be considered final in the tool if there is "Pending" selected in this field in any of the entries in the "Samples level data" form. It is the responsibility of the reporting country to update the final assessment in the corresponding report during the reporting period (until 31 March of the following year) to avoid mismatch in the number of cases between years.

• Sample ID*; open text field to report the unique identification number for each sample assigned by the reporting country. If the Sample ID is considered confidential by the reporting country, an alternative ID can be provided. However, the reporting country should keep a mapping table of the actual and alternative ID numbers. It is the responsibility of the reporting country to submit data which can be traced at all times.

• Part*: represents the main anatomical area of the sample. The available options are:

  • Blood
  • Brain
  • Obex
  • Retropharyngeal lymph node (RPLN)
  • Other head lymph node (other than RPLN)
  • Tonsil

• National case ID~: open text field to report the unique identification number for each sample assigned by the reporting country. The field is mandatory for all Positive and Inconclusive/Pending cases and if it is considered confidential by the reporting country, an alternative ID can be provided. However, the reporting country should keep a mapping table of the actual and alternative ID numbers. It is responsibility of the reporting country to submit data which can be traced at all times. The syntax of the National case ID should be such that they cannot be confused with cases from other reporting countries. A proposed syntax is to include the ISO code for the reporting country followed by the type, year and the national identifier of the case. For example, the first case of CWD in Croatia in 2018 would be: HRCWD20180001 or HR/CWD/2018/0001. In the case of CWD, the national case ID should be the same for the two different samples of the same animal.

• Animal ID~: open text field to report the unique identification number for each animal assigned by the reporting country. The field is mandatory for all Positive and Inconclusive/Pending cases and if it is considered confidential by the reporting country, an alternative ID can be provided. However, the reporting country should keep a mapping table of the real and the alternative ID numbers. It is responsibility of the reporting country to submit data which can be traced at all times.

• Herd ID: open text field to report the unique identification number for each herd of origin of the cervid assigned by the reporting country. It is only applicable to farmed/captive and semi-domesticated cervids. If the field is considered confidential by the reporting country, an alternative ID can be provided. However, the reporting country should keep a mapping table of the real and the alternative ID numbers. It is responsibility of the reporting country to submit data which can be traced at all times.

• Holding ID: open text field to record the unique number of the holding of origin of the animal, assigned by the reporting country. Note that there could be multiple Herd IDs within the same Holding ID. It is only applicable to farmed/captive and semi-domesticated cervids. If the Holding ID is considered confidential by the reporting country, an alternative ID can be provided. However, the reporting country should keep a mapping table of the real and the alternative ID numbers. It is responsibility of the reporting country to submit data which can be traced at all times.

• Sampling Day: the available options include numbers between 1 and 31 and the blank option

• Sampling area~: it is the area where the holding of origin is located. The options available in the drop-down menu are those corresponding to the NUTS 2 level areas of the reporting country. It is mandatory for all Positive and Inconclusive/Pending cases.

• Index case~: pre-populated with "Yes". It is assumed that all CWD cases in wild animals are index cases. In farmed/captive and semi-domesticated animals, the option could also be "No" if previous cases have been confirmed in the same herd/holding. It is mandatory for all Positive and Inconclusive cases.

• Country of birth~: the available options include all reporting countries and the blank option. Since TSE tool version 2.0.0, the options "European Union", "Non European Union", "Unknown" are also available. It is mandatory for all Positive and Inconclusive/Pending cases that are not wild animals.

• Year of birth~: the available options include values between 1995 and 2030. It is mandatory for all Positive and Inconclusive/Pending cases that are not wild animals.

• Month of birth: the available options include 12 values between January and December. It is mandatory for all Positive and Inconclusive/Pending cases that are not wild animals.

• Born in the flock: the available options are "Yes" and "No" and the blank option. If the animal was born in the herd referred to in Herd ID, select "Yes". It only applies to Farmed/captive and semi-domesticated cervids.

• Breed: open text field to report breed of the animal, if known. For cervids, it would refer to variety.

• Comment: open text field to be used in case additional information about the case and not provided so far needs to be reported (to be filled only if strictly necessary).
