1.
What is Malaria?
Correct Answer
B. A disease caused by a parasite
Explanation
Malaria is a disease caused by a parasite. The parasite, known as Plasmodium, is transmitted to humans through the bite of infected female Anopheles mosquitoes. Once inside the human body, the parasites multiply in the liver and then infect red blood cells, causing symptoms such as fever, chills, and flu-like illness. If left untreated, malaria can be life-threatening. Therefore, it is important to diagnose and treat the disease promptly.
2.
Can malaria result in death?
Correct Answer
A. Yes
Explanation
Malaria can indeed result in death. It is a life-threatening disease caused by parasites that are transmitted to humans through the bites of infected mosquitoes. If left untreated or not treated promptly and effectively, malaria can cause severe complications such as organ failure, anemia, and cerebral malaria, which can be fatal. Therefore, it is crucial to diagnose and treat malaria promptly to prevent the risk of death.
3.
In an infected person's body, what is being attacked by malaria?
Correct Answer
C. The red blood cells
Explanation
Malaria is caused by a parasite called Plasmodium, which is transmitted to humans through the bite of infected mosquitoes. Once inside the body, the parasites invade and multiply within the red blood cells, causing them to burst and release more parasites. This cycle of invasion and destruction of red blood cells leads to the characteristic symptoms of malaria, such as fever, chills, and anemia. Therefore, the correct answer is the red blood cells.
4.
What spreads malaria?
Correct Answer
D. Mosquito
Explanation
Mosquitoes spread malaria because they are the primary carriers of the malaria parasite. When a mosquito bites an infected person, it ingests the malaria parasites along with their blood. The parasites then reproduce inside the mosquito and when it bites another person, it injects the parasites into their bloodstream, thus spreading the disease. Flies, worms, and ants do not play a significant role in the transmission of malaria.
5.
Can malaria be prevented through using preventive drugs?
Correct Answer
A. Yes
Explanation
Preventive drugs, such as antimalarial medications, can be used to prevent malaria. These medications are typically taken by individuals who are traveling to or living in areas where malaria is prevalent. They work by killing the malaria parasites in the bloodstream before they cause symptoms. Therefore, using preventive drugs can help reduce the risk of contracting malaria.
6.
Can malaria be cured?
Correct Answer
B. If the infection is detected early.
Explanation
If the infection is detected early, malaria can be cured. This is because early detection allows for prompt treatment and intervention, which can effectively eliminate the malaria parasite from the body. Early detection also helps prevent the progression of the infection and the development of severe complications. However, if the infection is not detected early, it can become more difficult to treat and may require more aggressive interventions. Additionally, the statement does not mention anything about the age of the infected person, so it can be assumed that early detection is beneficial for individuals of all ages.
