Women and girls accounted for 45% of all new HIV cases. HIV is, for most, a treatable chronic health condition, and people diagnosed with HIV at an early stage can expect to live long and healthy lives with access to antiretroviral therapy. There is evidence, however, that people with HIV are more likely to develop certain age-related diseases, including cardiovascular disease, chronic airway disease, kidney failure, liver failure, cancer, type 2 diabetes and other complications. People with HIV also continue to experience intersecting social stigma, which affects their health outcomes compared with the general population. Amid recent US-led cuts to foreign aid, which risk threatening the long-term stability of the global HIV response, it is vital that clinicians maintain a working knowledge of HIV and its potential complications because, in the absence of international support, robust clinical expertise will become increasingly important in ensuring continuity of care, safeguarding vulnerable populations and protecting decades of progress.</div></div>","PeriodicalId":74157,"journal":{"name":"Medicine (Abingdon, England : UK ed.)","volume":"54 5","pages":"Pages 361-365"},"PeriodicalIF":0.0,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147828314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They operate at the three levels of prevention in public health: preventing transmission and acquisition of HIV (primary prevention), reducing the severity of HIV infection through early detection and diagnosis (secondary prevention), and improving the quality of life for people living with HIV through treatment and support (tertiary prevention).
