Researchers surveyed nine high-burden countries and received responses from eight: Armenia, Azerbaijan, Belarus, Kazakhstan, Kyrgyzstan, the Republic of Moldova, Turkmenistan and Uzbekistan. The survey covered testing, treatment regimens, service delivery and barriers to implementation.

Most responding countries reported national guidelines broadly aligned with international standards. However, availability and payment coverage for testing and medicines varied, reflex PCR testing was limited, elastography coverage was restricted, and hepatitis C treatment in harm-reduction settings was uncommon.
