Question

Find the odd one out : Chicken pox, Rubella, Flu, Meningitis

This question was previously asked in
RRB NTPC 2015 CBT 1 Question Paper (29-Mar-2016) (Shift 1)
The correct answer is
Meningitis

The question asks to identify the disease that is different from the others listed: Chicken pox, Rubella, Flu, and Meningitis.

Identifying the Odd Disease Out

Let's examine the nature of each listed condition:

  • Chicken pox: A highly contagious disease caused by the varicella-zoster virus.
  • Rubella: Also known as German measles, this is a viral infection caused by the rubella virus.
  • Flu: Short for influenza, this is a contagious respiratory illness caused by influenza viruses.
  • Meningitis: This refers to the inflammation of the meninges, the membranes that surround the brain and spinal cord. Importantly, meningitis can be caused by various pathogens, including viruses, bacteria, and fungi. Bacterial meningitis is particularly serious and distinct from common viral infections.

Reasoning for Exclusion

Chicken pox, Rubella, and Flu are all specific viral diseases. Meningitis, however, describes inflammation of the meninges and can have multiple causes, notably bacterial infection, which differentiates it significantly from the other three options, which are exclusively viral.

Therefore, Meningitis is the odd one out.

The correct option is 4.
