Previously just under half of covid-19 cases were detected by testing, but since omicron emerged this figure had dropped to under a third, he said.

A more recent preprint from Japan (a study that is yet to be published in a scientific journal) looked at viral shedding attributed to omicron.

Kritikos A, Caruana G, Lazor-Blanchet C, Currat M, Chiche JD, Vollenweider P, Bart PA, Opota O, Greub G. Microbiol Spectr. The decision for cessation of isolation according to the presence of symptoms could be reconsidered until further studies disapprove of our results. The latest results could mean that "the virus establishes a very local infection in the upper airways and has less chance to go and wreak havoc in the lungs", which might make it easier "to hitch a ride on material expelled from the nose and mouth, allowing the virus to find new hosts". The State of Palestine reported its first three cases, in returnees from abroad. But most people will spend a couple without any signs they are ill - unaware they are in the viruses incubation period. Of course some people won't see any at all throughout their entire infection.

The findings of the study demonstrated that fully vaccinated COVID-19 case-patients with mild or asymptomatic SARS-CoV-2 omicron variant infection shed infectious virus in samples for six to nine . News-Medical. Some argue that omicron is mild and is not resulting in a spike in hospitalisations, but it must be remembered that this wave is sweeping through a population with a considerable degree of protection derived from combinations of natural infection and vaccination-induced immunity. From nanoparticle-based enrichment to mass spec refinements, they explore how these tools facilitate unbiased, deep, and rapid proteomics. [117], New Zealand has reported three more Omicron cases at the border.
