Women in Zimbabwean society and culture are often seen as inferior, treated as objects, and viewed in subordinate roles in history and philosophy. Ubuntu, an African philosophy's spiritual aspect instills the belief that boys should be more valued than girls as boys pass on lineage and the belief system places high value in respecting one's ancestors. A common expression used in court, "''vakadzi ngavanyarare''", translates to "''women should keep quiet''" and as a result women are not consulted in decision-making; they must implement the men's wishes. The subordination of women in Zimbabwe and the cultural forces which dictate what they must be, have led to deaths and the sacrifice of professional advancement in order for them to fulfill their roles as wives, mothers, and subordinates. Women are taught that they must never refuse their husband's sexual advances, even if they know they are infected with HIV from being unfaithful. As a result of this practice, Zimbabwean women aged 15–49 have an HIV prevalence rate of 16.1% and make up 62% of the total population infected with HIV in that age group.
