The global financial hub has identified several dozen Omicron infections via regular testing during quarantine but neither Omicron, nor other variants, have spread into the community in recent months.
The new measures require that returning air cargo crew spend three days in hotel quarantine before a period of home isolation. Most recent infections of air crew staff have been discovered in the first three days. Vaccination rates in Hong Kong are lagging those in many similar cities with less than 70% of the eligible population having received two doses of either China's Sinovac or Germany's BioNTech vaccines.
The South China Morning Post newspaper reported on Tuesday, citing unidentified sources, that the measure may soon be extended to schools.
