In July 2022, UNAIDS released the 2022 Global AIDS Progress Report: A Critical Moment, which shows that the pandemic response has stalled over the past two years due to the combined impact of the pandemic and other global crises, with dwindling resources, putting millions of lives at risk.
There were 1.5 million new HIV infections worldwide in 2021
About 650,000 people died from AIDS-related diseases
On average, 1 person dies every minute
The main ways of transmission of HIV are blood-borne transmission, sexual transmission, mother-to-child transmission, etc., once infected, it will destroy the body's immune function, and then cause opportunistic infection and tumors and other diseases. HIV spreads rapidly, with a low ** rate and a high fatality rate.
Among all the infected people, adolescents and the elderly have a rapid trend of infection. According to the UNAIDS Representative in China, global data shows that adolescents aged 15 to 24 account for 16 per cent of the global population, but account for 34 per cent of newly diagnosed HIV infections each year. In China, the number of HIV infections among adolescents is increasing year by year. More than 3,000 cases are reported each year among young students, and cases are reported in all provinces (autonomous regions and municipalities) across the country, most of which are transmitted through same-sex sexual activity.
In addition, the significant increase in AIDS cases among the elderly has also aroused widespread concern in society. China's 13th Five-Year Plan for the Containment and Prevention of HIV/AIDS lists the elderly as a key group for HIV/AIDS prevention and control in China. According to the "Core Information on AIDS Prevention and Control Publicity and Education" provided by the Center for AIDS Prevention and Control of the Chinese Center for Disease Control and Prevention, in 2018, new HIV-infected patients and AIDS patients were found in China1490,000 casesPeople aged 60 and over are nearly 320,000 cases, showing a trend of increasing year by year, and 95% of them are infected through heterosexual transmission
At present, the diagnosis of HIV infection mainly uses HIV antibody detection methods, in addition to the commonly used enzyme-linked immunoassay methods, in the context of increasing medical technology, the gold standard method with the characteristics of simple operation, convenient operation, fast detection speed and high sensitivity is also widely used in clinical practice, so as to better screen for HIV.
