Undetectable = Untransmissible in Thailand (888/64)

This is a cross-sectional study to assess awareness, knowledge, and implementation of the concept of U=U among Thai PLHIV and Thai HIV healthcare providers, as well as associated factors. Data will be collected on an online survey platform called Alchemer. Questions on the survey will evaluate awareness, knowledge, and implementation of U=U among participants, as well as collect sociodemographic information of participants.

Recruitment Recruitment will start with the distribution of a brief description of the survey, along with the link to the questionnaire itself. This will be distributed systematically through the use of the snowball sampling method on popular social networking platforms (such as Line, Instagram, WhatsApp, Facebook and Twitter), where 'seed' distributors, who may be categorised into different groups (such as age, gender identity and treatment facility for PLHIV or healthcare facility and type of healthcare provider for HIV healthcare providers), will share out links to a number of friends. Participants will be enrolled into the study once they click on the link leading them to the survey and complete the questionnaire. Informed consent process Consent will be obtained by action. A brief description of the survey will be distributed, along with the online link to the survey, which will be on SurveyGizmo. All data will be collected anonymously. A digitalised consent form will be presented to participants before they start the survey, which will outline the potential risks and benefits. All participants will be equal to or over the age of 18; therefore, parental consent is not needed. Questionnaires The questionnaire should take no more than 15 minutes to complete. The survey will be completed on Alchemer (formerly SurveyGizmo), a flexible, cross platform online survey software, or other popular online survey platforms with similar features, with the participant giving consent through action. Questions on the survey will evaluate awareness, knowledge, and implementation of U=U among participants, as well as collect sociodemographic information of participants.
