Question

A harmful condition which is also a potential saviour from a mosquito borne infectious disease

• A. Thalassemia
• B. Sickle cell anaemia
• C. Leukemia
• D. Pernicious anaemia

Answer 1

The correct option is B Sickle cell anaemia

Those who are carriers for the sickle cell disease (with one sickle gene and one normal hemoglobin gene, also known as sickle cell trait) have some protective advantage against malaria. Hence, the frequencies of sickle cell carriers are high in malaria-endemic areas.

So, the correct answer is 'Sickle cell anaemia'.
