Have you ever wondered if the itchier a mosquito bite, the more danger it presents?
According to a post I read on Stuff.co.nz the itchiness of a bite is determined by the reaction between the chemicals transmitted in the bite and the blood.
Mosquitoes need blood and when a mosquito bites it injects saliva to get the blood flowing.
The mixture of chemicals helps the mosquito suck up blood from the victim.
When a mosquito bites, the reactions vary and for younger children the itch is normally more severe.
The good news is as we build a tolerance, the itchiness seems to decrease. See more at: http://www.stuff.co.nz/life-style/well-good/teach-me/81479435/are-itchier-insect-bites-more-likely-to-make-us-sick
