Rohde, PhD, a virologist and professor of clinical laboratory science at Texas State University, tells SELF that many people have seen the outdoors as a get out of jail free cardbut that has never really been the case. The estimated overall AR in this investigation is consistent with the range of ARs observed in other Omicron transmission studies (3), and higher than those associated with some other SARS-CoV-2 variants. These findings underscore the importance of implementation of multicomponent prevention measures for reducing SARS-CoV-2 transmission in household settings, including from the Omicron variant (4). (The other layers are vaccination, masks and physical distancing.). With previous coronavirus variants, like alpha and delta, being outdoors provided good protection against infection, but with the newest Omicron subvariants, being at an outdoor event could be somewhat risky.

Id prefer that these events require proof of vaccination and same-day negative test result. According to an Epidemiological Update from the European Centre for Disease Prevention and Control (ECDC), "the current growth advantage for the BA.4 and BA.5 variants of concerncompared to the dominant variant BA.2 is probably due to their ability to evade immune protection against infection induced by prior infection and/or vaccination, particularly if this has waned over time." Omicron subvariant BA.5 may be the most contagious version of the SARS-CoV-2 virus that we've seen yetand even situations that have seemed relatively low-risk as of late, like outdoor gatherings, may now pose a greater threat.
