Hi Jonette!
Concerning infections by Mosquitos I never heard here in the south of Germany about that and we have always had many of these little animals. I react with rather heavy itching swellings if they bite me, but it doesn’t happen so often and when I see how my Paros love that food I can stand it for them ;-).
Whe have actually here a journalistic “blow up” about Tiger-Mosquitos from Asia which come from south of Europe here by trucks and cars. It is said that they would bring diseases. But they just bring the diseases from the men they had bitten before and they have no eternal live.
And their offspring – if they manage to breed here because of the climate change – can only bite middle European people and get their not so heavy infections…
