The first picture depicts how a mosquito’s life cycle
goes while the second instruction illustrates the steps dengue virus spread
through.
It shows four stages, according to the former, which a
mosquito develops from the eggs to the adult female. First, on the surface of the
water, eggs hatch into a larva. Next, underneath the water, a larva morphs into
a pupa. Then, it comes out of the pupa’s shell, leaving its skin on the water. Finally,
it becomes a perfect shape of mosquito that we encounter in our home. Unfortunately,
it is a source of contributing to diffusing dengue fever to human. Once a
mosquito bites a dengue-infected person, it is also contaminated. For around a
week, virus proliferates inside a mosquito. When a infected mosquito attacks
another healthy men, dengue virus begins to multiply within the men.
As can be observed, both two processes are required
four phases to complete. Mosquitos undergo four steps like eggs, larva, pupa,
and adult emerges. Unluckily, it can be a culprit to transmit dengue virus to
humankind with infected its body shifting virus from one to another. |
