Why does that happen?

And some people have extreme allergic reactions to this, and get bumps that end up swelling up to around 3-4 inches, like a bee sting allergic reaction occasionally. Except these fuckers are so small that it's sometimes impossible to even tell unlike bees.

It happens to me sometimes

The saliva is for keeping the blood flowing

And some people (like me) aren't allergic to the saliva so we don't get the bumps that everyone else has to get.

Exactly. Who would 'gladly allow a mosquito to' give them Malaria?!?!

Or Zika
