Mosquitoes carry a number of viruses and parasites that can be harmful to human health, including malaria, dengue, yellow fever, chikungunya, West Nile virus, and eastern equine encephalitis ...
Symptoms for both of the viruses, which can begin anywhere from three days to two weeks after the mosquito bite, include: Fever. Headache. Fatigue. Nausea. The viruses become a serious problem if ...
A mosquito's period of feeding is often undetected; the bite only becomes apparent because of the immune reaction it provokes. When a mosquito bites a human, it injects saliva and anti-coagulants. With the initial bite to an individual, there is no reaction, but with subsequent bites, the body's immune system develops antibodies. The bites ...
Mosquitoes have a slender segmented body, one pair of wings, three pairs of long hair-like legs, and specialized, highly elongated, piercing-sucking mouthparts. All mosquitoes drink nectar from flowers; females of some species have in addition adapted to drink blood. The group diversified during the Cretaceous period.

Zika virus replicates in the mosquito's midgut epithelial cells and then its salivary gland cells. After 5–10 days, the virus can be found in the mosquito's saliva. If the mosquito's saliva is inoculated into human skin, the virus can infect epidermal keratinocytes, skin fibroblasts in the skin and the Langerhans cells.
Mosquitoes seem particularly good at finding humans to bite, and now scientists have a better idea why. According to a new study, the insects have a multi-sensory strategy that involves odors ...
He thus proved that the mosquito was the vector for malaria in humans by showing that certain mosquito species transmit malaria to birds. He isolated malaria parasites from the salivary glands of mosquitoes that had fed on infected birds. [248] For this work, Ross received the 1902 Nobel Prize in Medicine.
