**Core Concept**
The National Vector Borne Disease Control Programme (NVBDCP) is a government initiative aimed at preventing and controlling vector-borne diseases in India. It focuses on diseases transmitted by mosquitoes, ticks, and other arthropods. The programme's primary goal is to reduce the incidence of these diseases and improve public health.

**Why the Correct Answer is Right**
KFD (Kyasanur Forest Disease) is a tick-borne viral hemorrhagic fever endemic to certain regions of India. Although it is a significant public health concern in those areas, it is not included in the NVBDCP. This is because KFD is primarily a zoonotic disease, meaning it is transmitted between animals and humans, and its prevention and control strategies differ from those for vector-borne diseases like malaria, filariasis, and kala-azar.

**Why Each Wrong Option is Incorrect**
**Option A:** Malaria is a major vector-borne disease in India, and its prevention and control are a key focus of the NVBDCP.
**Option B:** Filarial diseases, including lymphatic filariasis, are also targeted by the NVBDCP due to their significant public health impact.
**Option C:** Kala-azar, also known as visceral leishmaniasis, is another vector-borne disease that is included in the NVBDCP's scope.

**Clinical Pearl / High-Yield Fact**
It's essential to note that while KFD is not included in the NVBDCP, it is still a notifiable disease in India, and healthcare providers must report suspected cases to the relevant authorities.

**✓ Correct Answer: D. KFD**
