Q. Consider the following:

1. KFD is caused by a virus belonging to the Rhabdoviridae family.
2. The primary vector responsible for KFD transmission is the Haemaphysalis spinigera tick.
3. Human-to-human transmission of KFD is a significant concern during outbreaks.
4. The disease was first identified in the forests of Karnataka in the 1950s.

Which of the above statements is / are correct?
Answer: Only 2 and 4
Notes: KFD is caused by a virus of the Flaviviridae family, not Rhabdoviridae. Therefore, statement 1 is incorrect. Haemaphysalis spinigera tick is indeed the primary vector for KFD, making statement 2 correct. Human-to-human transmission does not occur in KFD, negating statement 3 and the first identification of the disease happened in the 1950s in Karnataka forests, verifying statement 4. Hence, only statements 2 and 4 are correct.
