Vectors: mosquitoes, ticks and transmitted agents
A vector is an organism that can participate in the transmission of an agent. The presence of a mosquito or tick does not show that an agent is circulating or that an infection has been transmitted. This category links diseases to landmarks on the ground and travel.
The distinctions that change reading
Territory and date
Read the maps with their period, legend and the distinction between imported cases and local transmission.
Exposure
Specifying the activity, the places and the measures already taken; a route allows for a finer reading than a whole country.
Practical issues
Do all mosquitoes transmit dengue or malaria?
No. The vector, agent and local conditions must be distinguished.
Before interpreting a sheet
Find the agent's name, the indicated routes and the primary source. Then check the date and territory of this source. A section helps to compare; it does not determine a person's medical conduct.
