Organize tick surveillance nationwide
ANSES calls for the implementation, as part of vector control actions (VCR), of surveillance of ticks of the genus Hyalomma at the national level, prioritizing:
the geographical areas identified as most at risk, the development of tools for early detection of the presence of Hyalomma ticks and the circulation of the pathogens they transmit, in particular the CCHF virus and parasites such as Theileria.
The purpose of this monitoring is to be able to adopt prevention and risk management measures according to the evolution of the situationand in particular the awareness of health professionals for the identification of indigenous human cases.
« Contrary to what exists for mosquitoes, no national monitoring system is organized for ticks although they transmit serious diseases such as CCHF but also Lyme disease or tick-borne encephalitis. To best prepare for the potential emergence of the CCHF virus on our territory, it is essential to strengthen the surveillance of ticks in France but also of those arriving from countries where the virus is currently circulating. These introductions can be made when the Hyalomma tick is attached to a migratory bird, or to an imported horse or cattle, for example. continues Elsa Quillery.
Such monitoring would benefit from relying on actions of sciences participatives such as the Citique system, set up as part of the plan to combat tick-borne diseases, which might be extended to ticks Hyalomma.
Developing research on Hyalomma and CCHF virus
The Agency also emphasizes the need to launch research programs to better understand the factors influencing the epidemiology and spatio-temporal dynamics of Hyalomma ticks and the CCHF virus. New knowledge is also needed to develop new antiviral molecules once morest this virus and develop a vaccine.
