Discussion

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 saliva of the house dogs should be periodically tested for the detection of rabies.

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

Answer: D

Correct answer: Data inadequate

The passage explains that the virus is present in the saliva of an infected animal, but it never discusses screening healthy dogs, nor the periodic testing of any animal. It gives precautionary measures for the bite victim - washing the wound, then cetavlon, tincture of iodine or spirit - not a programme of surveillance. The recommendation in the statement is simply not addressed.
