According to research published in HIV Medicine, Sweden is the first nation to achieve a major milestone in HIV treatment and prevention.

Sweden has achieved goals proposed in 2014 by the UNAIDS/World Health Organization (WHO).

The 90-90-90 goals propose that 90 percent of people living with HIV know their HIV status, 90 percent of people diagnosed with HIV are on sustained treatment, and 90 percent have durable viral suppression by 2020.

“We believe that Sweden is the first country to achieve the UNAIDS/WHO 90-90-90 goal,” the researchers wrote.

“In summary, the UNAIDS/WHO 90-90-90 coverage target of 73% of HIV-infected individuals with undetectable HIV RNA has been achieved, with 90% of all those infected diagnosed, 83% of those infected on ART [antiretroviral therapy], and 78% of those infected with a suppressed viral load (<50 copes/ml),” the authors said.

Researchers pointed to several reasons for Sweden's success, including small size of the epidemic, strict HIV reporting laws and free access to medicines.
