Dr. Derval Igoe:

As my colleague mentioned, a clinical advisory group was convened to determine who the criteria should be widened to include. The group we are calling 1B comprises those who are determined to be at highest risk of exposure. They are defined as non-monogamous gay, bisexual and other men who have sex with men and transgender women who have sex with men who self-report one or more of the following: bacterial sexually transmitted infection or primary genital herpes within the past six months; sex in a sex-on-premises venue such as a sauna, dark room, sex club etc. within the past six months; a person who has had group sex within the past six months; or a person who has had three or more sexual partners in the past three months. People can self-refer if they feel they have had those exposures and therefore are at high risk of exposure to the disease.
