QUESTION
In pox lesions, which stage is involved in the “spread” of virus?
OPTIONS
(A) Pustule
(B) Vesicle
(C) Macula
(D) None of the above
ANSWER
(B) Vesicle

During the vesicular stage of pox development, lesions contain fluid rich in virus and rupture can disseminate infectious material to nearby tissues or susceptible animals. Macules are early lesions and pustules are later inflammatory stages, making the vesicle the stage most associated with spread.
