nonewHIV.hk is an online platform devoted to the sharing of information relating to HIV prevention with special reference to Hong Kong. In the recent years there was a paradigm shift in the development of interventions to achieving HIV prevention, from a strictly socio-behavioural focus to one incorporating biomedical strategies, notably antiretroviral treatment. Pre-exposure prophylaxis (PrEP) and treatment-as-prevention (TasP) are 2 important examples of modern day HIV prevention activities. As these are new concepts, research has continued to be developed. While the underlying rationale is the same across all human populations, tailored intervention is needed in operationalizing initiatives encompassing PrEP or TasP. nonewHIV.hk is designed by likeminded researchers with an aim of contributing to the achievement of the ultimate vision of "no new HIV in Hong Kong". Based at The Chinese University of Hong Kong, nonewHIV.hk is commited to sharing information about HIV prevention, and introducing local research which is of interest to the community.
