INTRODUCTION
• HIV in Mexico is a concentrated epidemic driven by infection in MSM
• Late presentation remains the most important challenge
• Women represent 20% of affected population• Detection campaigns focus on high risk groups
that do not include women• The only screening strategy for HIV detection in
women is pregnancy• HIV infected women are particularly vulnerable and
represent a double challenge
www.aids2014.org
GOALS
• What are the sociodemographic and clinical
characteristics of Mexican women recently diagnosed with HIV infection?
• How are women diagnosed with HIV?
• Are there specific factors reflecting increased vulnerability in women infected with HIV?

CONCLUSIONS
• Women recently diagnosed with HIV in Mexico have vulnerability factors such as a high prevalence of physical and sexual violence, low level of education, pregnancies at young age, low incomes and acquiring HIV mainly through their stable partner
• Women are detected late, except for women diagnosed through pregnancy
• Most women (73%) are diagnosed because of an infected partner/offspring or being symptomatic
• Missed opportunities of earlier diagnosis and low rates of HIV testing were detected, during medical and prenatal care
www.aids2014.org
Consequences and perspectives
• Late diagnosis in women seems to be the result of a deficient health care system and lack of risk perception both from health care workers and women, in a context of high vulnerability and the absence of screening policies for non-pregnant women
• Strategies for early detection need to be reevaluated for women in countries with concentrated epidemics such as the one in Mexico
