Yes. Montreal currently requires the wearing of face masks only in healthcare settings and on public transport, which includes taxis, airports and railway stations. However,  conference organizers are committed to ensuring the health and safety of all delegates, some of whom may be immunocompromised. As such, all conference attendees above the age of five years old are required to wear a mask (e.g. surgical, KN95, N95) covering their nose and mouth in the AIDS 2022 venue, except when eating or drinking. We will have masks available at the venue, but would appreciate it if delegates bring their own.
