The World Health Organization is warning countries that the omicron coronavirus variant poses “very high” global risk — and is likely to spread internationally.
The newly identified omicron variant has 26 to 32 spike mutations, the WHO brief states, “some of which are concerning” in that they could make it more transmissible and better able to evade the body’s immune defenses.
“Depending on these characteristics, there could be future surges of COVID-19, which could have severe consequences, depending on a number of factors including where surges may take place,” the report says. “The overall global risk related to [omicron] is assessed as very high.” It added that “evidence for this assessment contains considerable uncertainty” and is subject to change.
The WHO recommends several actions that its member states should immediately take. Some are new, such as guidance on the marker that can be used to detect the newest variant. Some are consistent with well-known measures to stop the spread of the coronavirus, such as advice for governments to encourage people to wear masks, keep a safe distance from one another and avoid crowds to limit the spread of the virus.
As some governments have shut down borders and others are reinforcing public health rules, officials around the world stressed that the measures are designed to buy time to learn more about how the omicron variant spreads, what symptoms it causes and how it reacts to existing coronavirus vaccines. The Biden administration is encouraging more people to seek out booster doses to bolster their immunity to the coronavirus as the world awaits answers.
Coronavirus: What you need to know
Vaccines: The CDC recommends that everyone age 5 and older get an updated covid booster shot designed to target both the original virus and the omicron variant. Here’s some guidance on when you should get the omicron booster and how vaccine efficacy could be affected by your prior infections.
Variants: Instead of a single new Greek letter variant, a group of immune-evading omicron spinoffs are popping up all over the world. Any dominant variant will likely knock out monoclonal antibodies, targeted drugs that can be used as a treatment or to protect immunocompromised people.
Tripledemic: Hospitals are overwhelmed by a combination of respiratory illnesses, staffing shortages and nursing home closures. And experts believe the problem will deteriorate further in coming months. Here’s how to tell the difference between RSV, the flu and covid-19.
Guidance: CDC guidelines have been confusing — if you get covid, here’s how to tell when you’re no longer contagious. We’ve also created a guide to help you decide when to keep wearing face coverings.
