Covid variant tracking

Omicron is the most dramatic evolution yet. A lab in South Africa first sent up a warning flare in November after its sequencers spotted a virus genome with more than 50 mutations. Almost instantly, computers in Seattle, Boston, and London were using the data to spit out predictions: omicron was trouble, a variant likely to evade antibodies. 

One thing the sequencers can’t yet tell us is how, exactly, SARS-CoV-2 will evolve next. That’s why some say we should be tracking the germ even more closely. The majority of sequences are being generated in places like the UK, the US, and Denmark. But the virus can still evolve, unwitnessed, in regions without the capacity to sequence. Luckily, the quick work in South Africa to spot omicron and track its spread gave the world an early warning.

As part of our 10 Breakthrough Technologies series, meet the scientist who warned the world about omicron.
