Final answer:
An asymptomatic woman testing positive for HIV antibodies serves as a reservoir in the infection cycle, meaning she is a potential source of infection for others.
Step-by-step explanation:
A woman testing positive for the human immunodeficiency virus (HIV) antibody without showing symptoms can be considered an active carrier. In the context of the infection cycle, she represents a reservoir of the infection. A reservoir,
in terms of infectious diseases, refers to any person, animal, plant, soil, or substance in which an infectious agent normally lives and multiplies, on which it depends for survival, and where it reproduces in such a manner that it can be transmitted to a susceptible host. In this case, the woman carries the HIV infection and has the potential to transmit the virus to others, even though she is asymptomatic.
