Omicron transmission occurred in 124 (67.8%) of 183 households. This German snowman wears a protective mask over its banana nose and mouth, but experts say the risk of catching COVID outdoors is slim.

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). Building off other recent research which showed Omicron's heavily-mutated spike protein is more stable than the ancestral strain, and their own previous findings on SARS-CoV-2's level of infectiousness on various surfaces, the Hong Kong team explored what would happen if droplets containing Omicron the BA.1 lineage, specifically were applied to surfaces like stainless steel, paper, and glass.
