Giardia lamblia is a parasite that affects humans. Applying your knowledge, how could you
protect yourself from getting this parasite?
The most obvious way to be protected from this parasite is taking vigilance in being
hygienic by washing your hands often and taking the necessary precautions to exercise
caution when dealing with unsanitary conditions. . It is also important to avoid drinking
untreated water since there is a possibility of it being contaminated. To lessen the chances
of getting Giardia lamblia, people should remember to keep their mouths closed when
swimming in lakes, swimming pools or other bodies of water that might be contaminated.
Plasmodium vivax is the parasite responsible for malaria. Describe in detail how the
parasite is spread via mosquitoes.
The parasites are spread to people through the bites of infected female Anopheles
mosquitoes, called "malaria vectors." The mosquitoes obtain the parasite from infected
people when they bite them in order to obtain blood needed to nurture their eggs. Inside
the mosquito, the parasites reproduce and develop. When the mosquito then bites again,
the parasites contained in the salivary gland are injected and passed into the blood of the
next person being bitten.
