Malaria is caused by :

Question

Accepted Answer

Malaria is caused by:

Correct Answer: Option 1 - Plasmodium

Explanation:

1. **Plasmodium**: Malaria is a disease caused by a parasite known as Plasmodium. There are several species of Plasmodium that can infect humans, with Plasmodium falciparum and Plasmodium vivax being the most common. These parasites are transmitted to humans through the bites of infected female Anopheles mosquitoes. Once inside the human body, the Plasmodium parasites multiply in the liver and then infect red blood cells, leading to the symptoms associated with malaria, such as fever, chills, and anemia. Therefore, Option 1 is correct because it identifies the actual causative agent of malaria.

2. **Female Anopheles mosquito**: While the female Anopheles mosquito is the vector that transmits the Plasmodium parasites to humans, it is not the cause of malaria itself. The mosquito acts as a carrier that facilitates the spread of the Plasmodium parasites from one host to another. Therefore, Option 2 is incorrect because the mosquito is not the causative agent but rather the means of transmission.

3. **Culex mosquito**: The Culex mosquito is not involved in the transmission of malaria. It is known for transmitting other diseases, such as West Nile virus and filariasis, but not malaria. Therefore, Option 3 is incorrect because it refers to a different type of mosquito that does not play a role in the malaria transmission cycle.

4. **Virus**: Malaria is not caused by a virus; it is caused by a protozoan parasite, specifically Plasmodium. Viruses are entirely different types of pathogens that cause diseases such as the flu, HIV/AIDS, and COVID-19. Therefore, Option 4 is incorrect because it misidentifies the type of pathogen responsible for malaria.

In conclusion, the correct answer is Option 1 - Plasmodium, as it accurately identifies the parasite responsible for causing malaria.
