But mosquitoes don’t have red blood cells – their blood is a somewhat colourless fluid containing the blood cell equivalent called haemocytes – so the parasites instead escape to the mosquito’s saliva from the gut.
Do mosquitoes die from diseases?
Mosquitoes cause more human suffering than any other organism — over one million people worldwide die from mosquito-borne diseases every year. Not only can mosquitoes carry diseases that afflict humans, they also transmit several diseases and parasites that dogs and horses are very susceptible to.

Mosquitoes possess physical barriers such as a hard exoskeleton, and they lack an adaptive immune system, unlike higher organisms. Mosquitoes entirely depend on their innate immune system to fight infections caused by pathogens such as viruses, bacteria, fungi, and parasites [26,27,28].
What purpose does a mosquito serve?

Are there any health benefits to mosquito bites?
Now researchers find mosquito spit aggravates your immune system for days afterward. The findings could help scientists develop vaccines for mosquito-born diseases like Zika.
