Q22. Does this technique work equally well for the omicron variant as for delta?

Yes. In fact because of the very high transmissibility of the omicron variant, probably greater than measles, it can have a much greater effect on reducing COVID-19 spread in enclosed spaces than any other mitigation method, but should applied in conjunction with other methods. We strongly suggest implementing the crosswind solution or one based on the concepts shown in the videos.  It will surely have a positive impact on reducing local case rates and reducing hospitalizations.
