Table 1 Summary of the 2004 analysis grid containing the possible actions according to the degree of virus activity.
Situation | Possible actions |
|---|---|
No virus activity | - Verify the dead Corvidae reports - Maintain preventive activities (media) |
Possible source of infection (infected Corvidae found) | - Target the geographical zone of activity and determine the population density - Assess clusters of dead Corvidae - Plan for mobile mosquito monitoring - Closely monitor equine cases - Maintain preventive activities (media) |
Probable source of infection (infected mosquitoes or both infected Corvidae and infected mosquitoes found) | - Target the geographical zone of activity and determine the population density - Prioritise the analysis of dead Corvidae in the affected region - Assess clusters of dead Corvidae - Assess mosquito pool information (species and positivity) - Closely monitor equine cases - Integrate meteorological data into the analysis - Consider insecticide treatments - Increase preventive activities (media) |
Confirmed source of infection (human cases detected) | - Associate probabilities with potential acquisition site - Target the geographical zone of activity and determine the population density - Prioritise the analysis of dead Corvidae in the affected region - Assess clusters of dead Corvidae - Assess mosquito pool information (species and positivity) - Closely monitor equine cases - Integrate meteorological data into the analysis - Consider insecticide treatments - Increase preventive activities (media) |
