How Do You Get Malaria?
People can only get malaria in tropical zones where a lot of disease and
most of mosquitoes live and breed due to the warm muggy weather. Malaria is a
virus that is carried by mosquitoes that is found in tropical zones and travels
around by mossies. The process of malaria all begins
when the mosquito, while sucking on the blood injects the virus into the blood
stream. After a few days while infecting the blood it eventually attacks the
liver, as the haemoglobin and other substances in the blood go to through the
liver for the blood to be filtered, it the virus attacks the liver cells. It is
a virus because the parasites are taken in through the cell walls and is
chemically bonded to the cell, that can't escape. The surface proteins being
bonded to the cells that acts as the parasite can't
escape. therefore that means that as a virus it is in
the body forever and can't be removed. Malaria can be healed though, from white
blood cells stepping in to stop the infection from acting within the body, but
still remains. After having malaria it stays in your body as it is impossible
to have it again because the cells in your body are use to the malaria
infection.

Why
do mosquitoes bite?
Only female mosquitoes bite, and all mosquitoes live on the
sugar found in plant nectar, not on blood. But there is a reason females seek
blood. Female mosquitoes, unlike males, have a proboscis. This is a long thin
needle-like built-in syringe located at the mouth. They use this to impale
their victims, in order to fill their abdomens with blood. Proteins in the
blood are necessary to produce fertile eggs. Since males cannot produce eggs
they have no need for blood. Females require a new blood 'meal' for every nest
they lay, and produce about 250 eggs per meal. Mosquitoes lay eggs in standing
water where they hatch into squirming larva. The larva molt four times before going into the next stage of pupa.
Inside the hardened case of the pupa, the adult mosquito forms and eventually
hatches. Female mosquitoes live anywhere from one to several weeks depending on
the species and the environment. Some females can survive the winter to lay
eggs in the spring, before dying. Males generally live 4-5 days, and die after
mating. Mosquitoes have been evolving for 30 million years. During that time
they've built an impressive array of sensory receptors. They possess chemical,
visual, and heat sensors, all designed to zero in on a blood source. The
chemical sensory receptors are located on the antennae, which allow them to
detect carbon dioxide. All mammals give off carbon dioxide, including humans.
Our skin excretes the gas, as does our breath. A mosquito can detect this scent
from 100 feet (30 meters) away. Insect repellents containing the active
ingredient, DEET, work by confusing the chemical receptors of the mosquito so
that they cannot zero in on the source of the carbon dioxide. When a mosquito
bites it injects a small amount of saliva that thins the blood so it doesn't
coagulate in the narrow channel of the proboscis. When it's done feeding, some
of this saliva remains in the wound. This causes an immune system response and
itching. A welt forms, known as a wheal, and the body goes to work breaking
down the proteins from the saliva. The bite will continue to itch until the
body has broken down all of the proteins. Mosquitoes can carry diseases that can
be transferred to humans through their bite. Some of these are malaria,
encephalitis,
