The surveillance information you provide on the submission form is recorded in the VIDA database, together with any diagnosis reached. VIDA is a national database, providing analysis of all diagnostic submissions to APHA and Scottish Rural College surveillance centres. Diagnoses follow strict criteria. VIDA allows monitoring of diagnoses, clinical syndromes and disease trends and epidemiological features associated with these. Submissions where a diagnosis is not reached (DNR) after reasonable testing are also scrutinised to determine whether they provide any evidence of a new or (re)emerging threat. The Species Expert Groups produce monthly and quarterly surveillance reports
