Is the spread of viruses from mosquitoes significant?

For those of us who spend a fair amount of time out-of-doors, it's not at 
all uncommon to see mosquitos settle on you that are already partially 
filled with blood, and there doesn't seem to be any doubt that viruses 
circulate in blood.   If you're standing beside another person and both are 
dislodging mosquitos during vain attempts to squash them, it seems to me 
that there's a very good chance that one which was sucking on someone else 
could begin taking your blood.  Thus, the key question would seem to be 
whether people-hopping mosquitos can inject, as well as extract, blood and 
any viruses that may be in the blood.
