Human Health and Disease

Common infectious diseases and their pathogens, innate and acquired immunity, vaccines, AIDS, cancer, and drug and alcohol abuse are the syllabus here. NEET tests recall: match pathogen to disease and symptoms, and keep antibody types and immunity terms straight.

Exam rules change between cycles. Confirm dates, syllabus and pattern against NTA's official site. We are not NTA.

Weightage: what the paper actually did

Human Health and Disease carried 2 questions in the NEET 2026 paper. One paper is a data point, not a destiny: NTA moves weight between chapters every cycle, which is why the weightage tables deserve care. The stable facts are the paper's shape: 180 questions, 720 marks, +4 right, −1 wrong.

Answer and explanation

Answer: A

Infection begins when a female Anopheles mosquito injects sporozoites into the human during a bite (E). Sporozoites travel through the blood to the liver (D), multiply asexually in liver cells and burst out into the blood (B), then invade and multiply asexually in RBCs, rupturing them (A). Finally gametocytes develop in the RBCs (C) to be taken up by the mosquito. Correct order: E, D, B, A, C.
