Human immunodeficiency virus, which affects the immune system. Effective treatment enables long, healthy lives and sustained viral suppression prevents sexual transmission.

Current public-health or clinical guidance
What it can support
Service pathways, health definitions and recommended public-health or clinical actions within its stated scope.
Important limitation
General guidance cannot assess an individual’s symptoms, exposure, medicine, contraindications or urgency.

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.
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.

HIV
The virus that targets parts of the immune system and is treated with antiretroviral medicine.
AIDS
A term for advanced HIV-related immune damage and particular illnesses; effective treatment prevents progression.
Viral load
The amount of HIV measured in blood, used to monitor treatment response.
Undetectable
Viral load suppressed below the test's reporting threshold; sustained suppression prevents sexual transmission.
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.

Questions you could ask a professional
What possible causes should be considered?
Could medicines, treatment, pain, hormones or another condition contribute?
Which symptoms or changes would need urgent review?
What options fit my priorities, access needs and health history?
These prompts do not replace assessment and do not imply that every reader needs professional care.
