[85], Queensland, Australia health authorities detect the first case of the variant in the state, alongside the first identification ever of a genetically distinct 'Omicron-like' variant. Taking the swab sample correctly is crucial to the test performance, and these require the tester to report the test result appropriately. This suggested the probability of variations in the viral replication kinetics.

Paul, Sangeeta. A few studies have suggested a slightly shorter period of viral shedding in people with no symptoms, but decisions on national policy must be based on all infections, not just a sub-set.

Generally people are feeling like they have a bad cold with Omicron, and tend to bounce back within the seven days of isolation, although may be feeling tired for a week to follow. Previous studies suggest that the peak transmission period for people with other variants was between two days before symptoms emerged and three days afterward, with virus shedding peaking on or before symptom onset.2 The Japanese study suggests that with omicron, the peak of virus shedding may be two or three days later, Hunter said. Language links are at the top of the page across from the title. However, whether the duration of shedding of viable virus differs between omicron and previous variants is not well understood.
