Relationship between vaccination type and clinical case of LSDV: Neethling strain vaccine did not show any deaths of LSD, and the lower number of diseased animals compared by sheep pox vaccine. Unvaccinated and animals with unknown condition of vaccination recorded the highest diseases and deaths of LSD.

The CAM showed congestion with clotted blood inside blood vessels and Pock lesions are prominent in the form of streaks white lines (black arrows) after 3rd passage as shown in A and B.
