Question

SCID patients have ____________

• A. no working immune system
• B. functional immune system
• C. weak digestive system
• D. chronic anaemia

Answer 1

The correct option is A

no working immune system

The condition in which the immune system loses its ability to fight infectious diseases caused due to genetic defects or extrinsic factors is called immunodeficiency.
If the immunodeficiency is caused due to genetic defects it is called primary immunodeficiency. For example - SCID
Severe combined Immunodeficiency Syndrome or SCID patients have no working immune system, which makes them highly susceptible to everyday infections caused by various pathogens that the immune system could combat quite easily.
