2.1.6 What is active rabies surveillance?

Active rabies surveillance is targeted, preferably based on risk factors, and typically initiated by the investigator with a designed sampling scheme to meet specific disease management needs (the investigator decides which specific information should be collected by a given observer). Some key risk factors in formulating an active surveillance scheme may include: species, groups of species, specific areas, time of year, types of habitats, period since the last case or outbreak, and others. For example, considering bat rabies in Europe, active surveillance was defined as the sampling of free-living live bats for measuring antibodies in sera and the presence of virus in the mouth of bats, superimposed upon the passive public health surveillance system which includes testing of suspect bats that expose a person.
