what specific drug, a highly potent kind of opioid, was cited as a major factor in a recent, record number of overdose deaths in the u. s.?

answer:

there is no cure for hiv, although antiretroviral treatment can control the virus, meaning that people with hiv can live long and healthy lives. most research is looking for a functional cure where hiv is reduced to undetectable and harmless levels in the body permanently, but some residual virus may remain. most commonly hiv-antivirals are taken also known as nucleoside/nucleotide reverse transcriptase inhibitors (nrti's).
