“…As CCHF virus is an RNA virus, it would certainly have been better to store ticks alive at −80°C to detect it, but in this study different people (hunters, breeders, staff of PNRC and ONCF) from different locations have collected ticks, preventing the storage of alive ticks at −80°C. However, as indicated above, CCHF RNA was detected recently in one Hyalomma tick collected on a migratory bird in Italy, and all the collected ticks of this study was conserved in 70° ethanol at −20°C (Mancuso et al, ) showing there is apparently no difficulties to detect CCHF RNA with this storage method. Because of the high frequency of Hy.…”

“…Recently, CCHF RNA was reported in a nymph of Hy. rufipes on a migrating bird on the small Italian island of Ventotene, pointing to migrating birds as a possible introduction pathway for the CCHF virus into western Europe (Mancuso et al, ). Hyalomma rufipes , a significant natural vector of CCHF virus in sub‐Saharan Africa, was ever found on migrating birds in Corsica (Pérez‐Eid, ).…”

Corsica is a mountainous French island in the north‐west of the Mediterranean Sea presenting a large diversity of natural environments where many interactions between humans, domestic animals and wild fauna occur. Despite this favourable context, tick‐borne pathogens (TBPs) have not systematically been investigated. In this study, a large number of TBPs were screened in ticks collected over a period of one year from domestic and wild hosts in Corsica. More than 1,500 ticks belonging to nine species and five genera (Rhipicephalus, Hyalomma, Dermacentor, Ixodes and Haemaphysalis) were analysed individually or pooled (by species, gender, host and locality). A real‐time microfluidic PCR was used for high‐throughput screening of TBP DNA. This advanced methodology enabled the simultaneous detection of 29 bacterial and 12 parasitic species (including Borrelia, Anaplasma, Ehrlichia, Rickettsia, Bartonella, Candidatus Neoehrlichia, Coxiella, Francisella, Babesia and Theileria). The Crimean–Congo haemorrhagic fever (CCHF) virus was investigated individually in tick species known to be vectors or carriers of this virus. In almost half of the tick pools (48%), DNA from at least one pathogen was detected and eleven species of TBPs from six genera were reported. TBPs were found in ticks from all collected hosts and were present in more than 80% of the investigated area. The detection of DNA of certain species confirmed the previous identification of these pathogens in Corsica, such as Rickettsia aeschlimannii (23% of pools), Rickettsia slovaca (5%), Anaplasma marginale (4%) and Theileria equi (0.4%), but most TBP DNA identified had not previously been reported in Corsican ticks. This included Anaplasma phagocytophilum (16%), Rickettsia helvetica (1%), Borrelia afzelii (0.7%), Borrelia miyamotoi (1%), Bartonella henselae (2%), Babesia bigemina (2%) and Babesia ovis (0.5%). The high tick infection rate and the diversity of TBPs reported in this study highlight the probable role of animals as reservoir hosts of zoonotic pathogens and human exposure to TBPs in Corsica.

“…Des virus appartenant à cette même clade ont également été identifiés au Maroc, chez des oiseaux, ce qui laisse entrevoir une possible introduction du virus en Espagne via des oiseaux migrateurs [42]. De même, une tique porteuse d'un virus de cette clade III a été récoltée sur un tarier des prés (Saxicola rubra), une espèce de passereau, sur l'île de Ventotene, au large de Naples en Italie, indiquant une possible présence du virus sur le territoire italien [43]. Les souches de virus présentes en Corse n'ont pas encore été identifiées.…”

La fièvre hémorragique de Crimée-Congo, une future problématique de santé en France ?

Le virus de la fièvre hémorragique de Crimée-Congo (CCHFV) est l’agent étiologique d’une fièvre hémorragique grave affectant l’Afrique, l’Asie et le sud de l’Europe. Les modifications climatiques de ces dernières décennies induisent depuis peu une remontée de l’aire de distribution de ce virus. Encore peu de données scientifiques sont disponibles sur les interactions avec son vecteur, la tique, ou sur sa biologie propre. Cependant, la présence avérée d’infections humaines en Espagne et des sérologies positives dans le cheptel corse pourraient bien concentrer l’attention sur ce pathogène. Cette revue fait le point sur l’évolution des connaissances éco-épidémiologiques de ce virus, notamment en Europe et plus particulièrement en France.
