The UK plans to diagnose 95% of people living with HIV by 2025 and is in a strong position to eliminate HIV infection by 2030, the University of Cambridge’s MRC Biostatistics Unit and Public Health England (British Public Health Services). PHE) researchers say.
In 2014, UNAIDS set an ambitious goal of 90-90-90 by 2020. That is, 90% of all people living with HIV will know their HIV status. 90% of all people diagnosed with HIV receive continuous antiretroviral therapy. 90% of all people receiving antiretroviral therapy receive virus suppression.
According to the Cambridge and PHE team, an estimated 105,200 people lived with HIV in the UK in 2019, 94% of whom were aware of HIV status. In addition, 98% of people diagnosed with HIV were treated, and 97% of these were suppressed by the virus. In other words, Britain had already achieved its UNAIDS goals.
In today’s publication Lancet Public HealthResearchers have analyzed evidence from multiple UK HIV-related monitors, demographics, and survey datasets, from a one-year estimate of HIV prevalence to an estimate of trends in HIV prevalence over time. Expanded to. Trends in the number of people living with HIV, the proportion of people unaware of HIV infection, and the corresponding prevalence of undiagnosed HIV have been reported.
According to their analysis, the estimated number of people living with HIV between the ages of 15 and 74 who were unaware of the infection was halved from 11,600 in 2013 to 5,900 in 2019, with a corresponding prevalence of 1,000. It decreased from 0.29 per person to 0.14.
At the same time, as the number of people diagnosed with HIV increased, the total number of people living with HIV increased from 83,500 to 92,800 over the same period. Therefore, the proportion of people living with HIV diagnosed with infection has steadily increased from 86% in 2013 to 94% in 2019, reaching the UNAIDS target in 2016 and even earlier in 2013. For black African heterosexuals.
Professor Daniela de Angelis of the MRC Biostatistics Unit, the lead author of the study, said: It is already a few years ahead of the UNAIDS 2020 target, with the goal of reaching 95% of diagnoses by 2025 and eradicating HIV infection by 2030.
Dr. Anne Presanis of the MRC Biostatistics Unit said: There is also evidence that some population subgroups missed the opportunity to diagnose HIV infection. “
In the UK, gay, bisexual, other men, and black-African heterosexuals who have sex with men are imbalanced in the effects of HIV, with an undiagnosed HIV positive rate per population in 2019. , Much higher than heterosexuals in other ethnic groups. However, the prevalence of undiagnosed HIV within these communities has dropped dramatically. The prevalence of gay, bisexual, and other men who have sex with men fell from 13.9 to 5.4 per 1,000, and the prevalence of heterosexuals in Black Africa fell from 3.3 to 1.7 per 1,000. .. population.
In London, the prevalence of undiagnosed HIV dropped dramatically during the study period compared to other parts of the United Kingdom, dropping from 0.20 per 1,000 to 0.11 outside London, compared to 0.74 per 1,000. Reduced from 0.31.
While the Sexual Health Clinic offers free and confidential HIV testing to all clinic participants, researchers have found that among heterosexual groups of non-Black African ethnic groups, 2019 clinic participants The undiagnosed prevalence was estimated to be more than 30 times higher than those who did not participate last year. this is, Sexually transmitted disease clinic There is a lack of opportunity to test participants. This is a UK public health service survey showing that among individuals outside the subgroup at highest risk of HIV infection, the percentage of people who refused HIV testing increased to more than 1 in 4 (27%) in 2016. Is consistent with.
Researchers say their estimates have important implications for efforts to eradicate HIV infection in the United Kingdom and the United Kingdom.
Dr. Valerie Delpech, Head of the HIV Team for Public Health England, said: Responses to end HIV infection have been further amplified among people at high risk of HIV, but further reductions in the number of people who remain undiagnosed with HIV will be very difficult in the coming years. Will be. Think of yourself as at risk of HIV.
“The priority is to encourage all sexual health clinic participants, regardless of ethnicity, to provide and accept HIV testing, not 73% who are currently testing. If we can increase the number of participants in the clinic, we will be tested and diagnosed, and if we reach a status that improves notification to our partners, we are more likely to eliminate HIV infection. ”
