If you begin to see an increase in skin irritations on your baby, like enflamed rosy spots, small red bumps or elevated red dermal spots with white centers, your child may be falling prey to opportunistic mosquitoes. Also, if a child is crying a lot and you can't figure out why, mosquito bites are a possible cause.
When a female mosquito bites (males don't bite), it extracts your blood. As it sucks out your blood, the female mosquito emits saliva that can enter your bloodstream. A fluid exchange occurs. That’s how a mosquito can be infected with a disease by biting an organism, then become a vector and spread that disease the next time it bites — and exchanges fluid with — another living organism. Infections coming from these airborne pests are passed into the blood.
