WNV Flashcards
WNV is present only in Africa.
F.
Mosquitoes are the principle vectors of the WNV.
T.
Eq + humans do ø play a significant role int he transmission of WNV.
T.
The weather does ø influence the occurrence of WNF outbreaks.
F.
Eq are the reservoirs host of WNV.
F.
The weather influences the emergence of WNV outbreaks through it’s effect on mosquito propagation dynamics.
T.
The sero- diagnostics of WNV is complicated by cross- reactions with related flaviviruses.
T.
The WNV is genetically uniform, but atleast 15 serotypes are known.
F.
Certain predatory bird sp are particularly sensitive to WNV infections.
T.
The use of repellents may reduce the risk of ifnection with WNV.
T.
Fomites play the most significant role in the transmission of WNV.
F.
WNV typically causes reproductive problems in cattle.

Different genetic lineages of WNV are circulating in Europe.
T.
WNV mainly causes diarrhea in sheep.
F.
WNV typically causes reproductive problems in cattle.
F.
Wild birds are the natural hosts of WNV.
T.
Mammals are usually accidental, dead- end hosts of WNV.
T.
WNV causes central nervous signs in 80 - 90% of the infections.
T.
WNV outbreaks usually develop in the end of summer + in autumn.
