Malaria is caused by which of the following?
Detailed Explanation
📌 Core Theoretical Concept:
Malaria is a vector-borne infectious disease caused by a protozoan parasite known as 'Plasmodium'. The primary vector responsible for transmitting this parasite to humans is the female Anopheles mosquito. In Environmental Studies (EVS) and science pedagogy, understanding communicable diseases, their pathogens, and preventive measures forms a fundamental competency for primary school educators to teach health and hygiene effectively to children.
📊 Key Exam Points:
- Plasmodium falciparum and Plasmodium vivax are the most common species causing severe malaria in humans.
- Vibrio bacteria (Option a) is responsible for water-borne diseases like cholera.
- Fungi (Option c) typically cause dermatological infections such as ringworm.
- Aedes (Option d) is the vector mosquito responsible for transmitting dengue and chikungunya viruses, not malaria.

Deep Pedagogical Analysis:
Teacher eligibility exams (such as CTET Paper-1) frequently test the distinction between a disease-causing organism (pathogen) and its transmission agent (vector). Candidates must note that while the female Anopheles mosquito acts as the vector, Plasmodium is the actual causative organism. Pedagodically, teachers should design experiential learning activities to help students understand how stagnated water breeds vectors and how community health campaigns help control such epidemics.
