1. COMBINATION PREVENTION
MODULE 10

2. Goals of Prevention Define a chain of steps to prevention:
What is the ultimate goal of prevention?
What other aspects increase prevention?
Develop a 3 to 5 step process to reach your prevention goals.
For example….
Increase understanding or transmission and prevention
Reduce the probability of transmission in discordant sexual acts
Reduce unprotected sexual act
Prevent sexual HIV transmission
Decrease community viral load to hasten epidemic control
The goal of prevention is to prevent new HIV infections through a number of evidence-based interventions necessary to hasten epidemic control and achieve prevention and treatment targets. Taken together, prevention targets have the potential to transform the epidemic.

5. Combination HIV Prevention
Biomedical
Behavioural
Structural
Ask participants:
What does ’structural’ mean?
What does ‘biomedical’ mean?
What does ‘behavioural’ mean?

6. Combination HIV Prevention: Biomedical
Barriers to infection
Less likely to infect another
Less likely to get infected
Biomedical
Behavioural
Structural
Biomedical interventions use medical, clinical, and public health approaches designed to moderate biological and physiological factors to prevent HIV infection, reduce susceptibility to HIV, and/or decrease HIV infectiousness.

7. Biomedical Interventions
Biomedical interventions are those that directly influence the biological system through which the virus infects a new host. Biomedical interventions work by:
Blocking infection (e.g., male and female condoms)
Decreasing infectiousness (e.g., ART as prevention)
Reducing acquisition/infection risk (e.g., voluntary medical male circumcision, pre-exposure prophylaxis)

8. Biomedical Intervention and The Ecological Model
What aspects of prevention of transmission of HIV are related to “the every person” in terms of biomedical?
What about preventing the onslaught of disease (e.g., HIV or opportunistic infections)?
Where do we/people living with HIV intervene in biomedical prevention of HIV transmission?

9. Combination HIV Prevention: Behavioural
Biomedical
Behavioural
Structural
Sexual risk reduction
Use of services (health and other)
Involvement and familiarity

10. Behavioural Interventions
Behavioural interventions include behavior change communication programmes that use various communication channels (e.g., mass media, community-level, and interpersonal) that are:
Designed to encourage people to reduce behaviours that increase risk of HIV and increase protective behaviours (e.g., risks of having multiple partners and benefits of using a condom correctly and consistently)
Aimed at increasing the acceptability and demand for biomedical interventions
Building self-acceptance and emotional well-being

11. Behavioural Interventions and The Ecological Model
What aspects of prevention of transmission of HIV are related “the every person” and their interaction with their immediate social circle?
When is it related to “the every person” or persons in their family or their friends?
Where do we/people living with HIV leaders intervene in the behavioural prevention of HIV transmission?

12. Combination HIV Prevention: Structural
Legal and policy
Health systems
Stigma reduction
Reduction of negative socio- cultural and gender norms
Community development

13. Structural Interventions and The Ecological Model
What aspects of prevention of transmission of HIV are related to “the every person” and within certain social and political constraints and opportunities?
What structural aspects can we/people living with HIV have the most influence over?
Where can we/people living with HIV intervene in structural prevention of HIV transmission?
Where do we/people living with HIV more need allies?

14. Structural Interventions
Structural interventions address the critical social, legal, political, and environmental enablers that contribute to the spread of HIV, including:
Legal and policy reform
Reducing stigma and discrimination against people living with HIV and marginalised groups
Addressing gender inequality and gender-based violence
Increasing access to health and social services (including mental health)
Building social capital, economic empowerment, and other multi-sectoral approaches among marginalised groups
Education

16. Juan’s quote [Juan, diagnosed with HIV in 1997]
“I am like any other person. Being sero-positive does not stop or limit me, but on the contrary, it motivates me.”
