The omicron variant multiplies about 70 times faster inside human respiratory tract tissue than the delta variant does, scientists at the University of Hong Kong report. The variant also reaches higher levels in the tissue, compared with delta, 48 hours after infection.

Using "fake" or pseudoviruses, they found that omicron's spike protein — the region that binds to human cells, triggering infection — was much better at helping the virus enter human cells than the spike protein of delta or that of the original coronavirus.

"Strikingly, Omicron was 4-fold more infectious than wild type [the original version of the virus] and 2-fold more infectious than Delta," Garcia-Beltran and colleagues wrote in their study.

The data suggests omicron may be able to infect people at a lower dose than delta or the original variant, Garcia-Beltran says. "That's a very far-out interpretation," he cautions. "But we think it will probably pan out that way, given that we're looking at a variant with more efficient entry into human cells."

Mask up and be safe out there DUers. Maskholes will no doubt get it and spread it as much as they can. Not a good time to be around unvaccinated conservatives.
