委员会一直关注以下广泛问题：需要进一步了解传播动态；
The Committee continues to be concerned about a broad range of issues, including the following: the need for further understanding of transmission dynamics; the impact of the fear of stigma on health-seeking behaviour among MSM; the potential implications on rights-based delivery of care by Ministries of Health and other authorities; the challenges related to the use of public health and social measures to stop onward transmission, including isolation, access to testing and contact tracing, particularly because of multiple anonymous contacts; planned large local and international gatherings focused on MSM and associated public and private satellite events, conducive for increased opportunities for exposure through intimate sexual encounters and subsequent amplification of the outbreak; the need for continuous evaluation of interventions that may have an impact on transmission (e.g., one-dose versus two-dose vaccination regimens and vaccine effectiveness in general, given the apparent permucosal exposures that are causing infection in some cases); and the identification of key activities for targeted risk communications and community engagement, working in close partnership with affected communities, and providing the necessary support for community-led organizations to play their important role in the response to the outbreak.
