However only about 18% of the 1.2 million Americans who might benefit from the medications got a prescription last year, according to Health and Human Services Secretary Alex Azar.

The new strain is a part of the same family of virus subtypes that have fueled the global HIV pandemic, according to Abbott Laboratories, which conducted the research with the University of Missouri.

Treatment advances are keeping people with the virus alive longer, and those who adhere to therapy are expected to live into their mid-70s or longer.

Chinese researchers used the tool to give a patient blood cells that were altered to resist the AIDS-causing virus, the Associated Press reported.
