Rabies is a disease transmitted to man and animals through the bite of a rabies-infected animal, most commonly by dogs. It is caused by a virus present in the saliva of the infected animal which gets deposited in the wound of the bite victim, multiplies and travels towards the brain and spinal cord. If not treated, about half of such cases develop rabies. Symptoms of the disease start one to three months after the bite. Very few laboratory tests are available for the diagnosis of rabies in India. Precautionary measures include prompt washing of the dog bite wound with soap and water. The wound is also treated with cetavlon, tincture of iodine or spirit.

The bite of a rabies-infected animal to a healthy animal definitely results in the healthy animal developing rabies.

  • A.Definitely true
  • B.Probably true
  • C.Data inadequate
  • D.Definitely false

Answer: A

Correct answer: Definitely false

The passage supplies the figure that settles this: if not treated, about half of such cases develop rabies. Half is not all, so a bite cannot be said definitely to result in the disease - and if the wound is treated promptly the proportion is lower still. The word ‘definitely’ is what makes the statement false; without it the claim would have been a reasonable one.
