Plasmodium vivax causes:

Correct option is C

Ans. (c) Sol. The correct answer is (c) Malaria.
Plasmodium vivax is one of the species of the Plasmodium parasite that causes malaria, a serious infectious disease transmitted through the bites of infected female Anopheles mosquitoes. Malaria is characterized by symptoms such as fever, chills, and flu-like illness. Plasmodium vivax is one of the most common causes of malaria, especially in tropical and subtropical regions.
Explanation of each option:
· (a) Dengue: Dengue fever is caused by the dengue virus, transmitted by Aedes mosquitoes, not by Plasmodium vivax.
· (b) Chikungunya fever: Chikungunya fever is caused by the chikungunya virus, also transmitted by Aedes mosquitoes, and is unrelated to Plasmodium vivax.
· (c) Malaria: Correct answer. Plasmodium vivax is one of the causes of malaria, a disease characterized by fever, chills, and other flu-like symptoms.
· (d) Filariasis: Filariasis is caused by parasitic worms (e.g., Wuchereria bancrofti) and is transmitted by mosquitoes, but it is not caused by Plasmodium vivax.
Thus, Plasmodium vivax causes malaria.
