Question

Which of the following causes malaria?
(a) Plasmodium
(b) Hookworm
(c) Ascaris
(d) Filarial worm

Answer 1

It is a disease caused by a parasite. Each year, approximately 210 million people are infected with these diseases, and about 440,000 people die from the disease. Its symptoms usually start with shivering and chills, followed by a high fever, followed by sweating, and a return to normal temperature.

Complete answer:
-Malaria is a life-threatening mosquito-borne blood disease.
-The female Anopheles mosquito transmits it to humans.
-Plasmodium genus, the parasite in mosquitoes, is responsible for spreading malaria. Different types of Plasmodium are:
Plasmodium falciparum
Plasmodium malariae
Plasmodium vivax
Plasmodium ovale
Hence, Plasmodium causes malaria.

Additional Information: Mosquito transmission cycle
-Uninfected mosquito. A mosquito becomes infected by feeding on an individual who has malaria.
-Transmission of the parasite. If this mosquito bites you within the future, it can transmit malaria parasites to you.
-In the liver. Once the parasites enter your body, they visit your liver — where some types can lie dormant for as long as a year.
-Into the bloodstream. They leave the liver and infect your red blood cells when the parasites mature. This is when people typically develop malaria symptoms.
-On to the next person. If an uninfected mosquito bites you now within the cycle, it'll become infected together with your malaria parasites and may spread them to the opposite people it bites.
So the correct answer is ‘Plasmodium’.

Note: Because the parasites that cause malaria affect red blood cells, people also can catch malaria from exposure to infected blood, including:
-From mother to unborn child
-Through blood transfusions
-By sharing needles used to inject drugs
