Short Summary: John Snow International (JSI) UK define mainstreaming as a process through which organisations can begin to address HIV internally, both professionally and personally within an organisation as well as operationally through the programmes it supports. This is addressed through the training approach to mainstreaming HIV which JSI UK has developed in response to requests from the Department for International Development (DFID),UK, country offices, headquarters and the Foreign Office. JSI UK trainers offer a three stage package of training which includes sharing and discussing facts and fiction about HIV, exploring attitudes to the virus and people living with it, and finally organising exercises to promote creative thinking around how to mainstream HIV. Because of the sensitive nature of the issue JSI UK trainers incorporate gender issues throughout the process: when sexual issues are discussed groups are given the opportunity to split into gender specific sub groups. Interestingly, this opportunity is rarely used and participants have found it refreshing and informative working in mixed sex groups.
