good protection
against HIV.

•
Fluid of Transmission
Sexual Risk Factors
When One Partner Is HIV+
Substance Abuse/Use
Pregnancy & Childbirth
Pre-exposure Prophylaxis (PreP)
Post-exposure Prophylaxis (PEP)
Blood Transfusions & Organ/Tissue Transplants
33. Pregnancy & Childbirth
• HIV-positive mothers can transmit HIV to their babies.
• During pregnancy
• During vaginal childbirth
• Through breastfeeding
But with proper treatment and coordination with healthcare
providers, HIV-positive mothers can significantly reduce the risk
of transmitting HIV to their babies.
34. Pre-exposure Prophylaxis (PreP)
• PrEP, is a new HIV prevention method in which people who do
not have HIV infection take a pill daily to reduce their risk of
becoming infected.
• The pill, called Truvada®, (tenofovir and emtricitabine)
contains two of the many medications that can be used to
treat people who already have HIV.
• Prevent HIV from making copies of itself and turning into an
infection that’s spread throughout your body.
