[Impact of a national policy change on rapid diagnostic testing for HIV, hepatitis C and syphilis by lay providers in community-based organisations and local public health centres: a cross-sectional study].

Background: To improve the diagnosis of undetected infections with the Human Immunodeficiency Virus (HIV), the Hepatitis C Virus (HCV) and syphilis infections among key populations, Section 24 of the Infection Protection Act was amended. Since 1 March 2020, non-medical staff have also been permitted to perform rapid tests. This study aims to examine the impact of the legal change in low-threshold AIDS and drug services as well as in public health offices.
