…the Centers for Disease Control and Prevention has stated that HIV positive people whose virus is suppressed by antiretroviral therapy “have effectively no risk of sexually transmitting the virus to an HIV-negative partner.”
The CDC’s statement:
Scientific advances have shown that antiretroviral therapy (ART) preserves the health of people living with HIV. We also have strong evidence of the prevention effectiveness of ART. When ART results in viral suppression, defined as less than 200 copies/ml or undetectable levels, it prevents sexual HIV transmission. Across three different studies, including thousands of couples and many thousand acts of sex without a condom or pre-exposure prophylaxis (PrEP), no HIV transmissions to an HIV-negative partner were observed when the person was virally suppressed. This means that people who take ART daily as prescribed and achieve and maintain an undetectable viral load have effectively no risk of sexually transmitting the virus to an HIV-negative partner.
The report also reminds us that many HIV+ people are living without treatment and that 61% of gay and bisexual men who have been diagnosed with HIV have achieved viral supression.
