It is very easy to stray into and comment on other topics to reinforce your point. Taking the scientific approach of waiting for evidence before commenting on likely routes of infection may be seen as ‘sitting on the fence’, especially when media will want immediate answers. This includes personnel managing a site, assessing the risk of an outbreak, reducing the risk of disease emergence, involved in the diagnosis and surveillance of a disease, and controlling an outbreak. Training is particularly important for front-line personnel, who are likely to come into contact with an incursion or outbreak of disease first, such as, wetland managers and members of disease diagnostic teams. All appropriate stakeholders should be thoroughly trained in their roles and responsibilities in a disease emergency. More intense and specialised training is needed for personnel/professionals holding key positions, such as members of specialist diagnostic and surveillance teams, forecasting experts and animal and human health professionals. Moreover, training programmes should be comprehensive and regular, to accommodate the possibility that a disease may occur in any part of a country, and to allow for staff turnover. Training must extend to staff in remote areas, as well as to selected officials, such as local authorities. Back up staff for each position should also be trained, in the eventuality of absent front-line staff. It will not always be possible, or practical, to train all personnel to a high level of expertise in the diseases themselves. Knowledge of basic clinical, pathological and epidemiological features of diseases known to be important, or potentially important, to a site, together with an understanding of actions to be taken when the presence of disease is suspected, may suffice in many circumstances.

In caring for our colleagues we would do well to remember the words of Rabia Elizabeth Roberts: “We learn that our human- ity is more powerful than our expertise alone” (Hanlon 2008).
