HIV
Human immunodeficiency virus, which affects the immune system. Effective treatment enables long, healthy lives and sustained viral suppression prevents sexual transmission.
Sexual health
In brief
A treatable virus—not an identity, moral judgement or inevitable AIDS diagnosis.
HIV is a manageable long-term health condition with effective antiretroviral treatment. HIV and AIDS are not synonyms: AIDS describes a set of advanced consequences that can occur when untreated HIV has seriously damaged immunity. Early testing and treatment improve health and prevent onward sexual transmission.
A term for advanced HIV-related immune damage and particular illnesses; effective treatment prevents progression.
The amount of HIV measured in blood, used to monitor treatment response.
Viral load suppressed below the test's reporting threshold; sustained suppression prevents sexual transmission.
Transmission
HIV can be transmitted through particular sexual and blood exposures and from parent to child without effective prevention. It is not spread by everyday contact, sharing food, toilets, hugging or insect bites.
Likelihood depends on the exposure and whether a person living with HIV has a suppressed viral load. Stereotypes about identity are not a risk assessment.
Testing and diagnosis
Many people have no specific symptoms, so testing is the only way to know. Modern tests have window periods and reactive screens need appropriate confirmation.
A diagnosis should lead promptly to specialist HIV care. Confidentiality and non-discrimination are essential parts of safe access.
Treatment and U=U
Antiretroviral treatment suppresses viral replication, protects health and allows most people to live long lives. Adherence and clinical monitoring are individual care matters.
When viral load is maintained at undetectable levels through treatment, HIV is not sexually transmitted—summarised as U=U. This evidence should not be diluted by stigma.
Prevention options
Condoms, PrEP, PEP, sterile injecting equipment, testing and effective treatment all have roles. The appropriate combination depends on circumstances and informed choice.
HIV prevention does not replace contraception or prevention, testing and vaccination for other infections.
Non-graphic examples
What the umbrella may include
- Testing without waiting for symptoms.
- Starting specialist treatment promptly after diagnosis.
- Understanding that everyday household contact does not transmit HIV.
- Using U=U information in a stigma-free health discussion.
- Considering PrEP for an HIV-negative person with relevant ongoing exposure.
