If the testing was mandatory, women would have no rights at all to decided whether to take the tests. African women might lie about the status and nothing will be done to prevent the virus from being spread. If women can voluntarily get tested and counseled, African women will be keener to participate for the well being of themselves and their children. Women may react differently once they've seen others trying to get help. Women and children need to realize that help is available any time they might want it.
Women also feel mandatory testing is unnecessary because of the trust issues in their lives.
Women feel their partners would never share a needle or cheat on them with someone else. Without knowing what kind of activities your partner is engaging in, its hard to believe there's a chance you could contact the virus. Also, many of the times women are scared to ask their partners to use a condom. They're afraid their partners will reject or abandon them. This creates a problem when women are dependent on their partners for financial support.
