A new covid-19 variant called Omicron is spreading worldwide. It was first reported in Botswana and was then detected in South Africa, Hong Kong, Israel and Belgium. It is now a "virus of concern". Epidemiologists say this new strain could be very infectious. It may be able to evade protections our current vaccines give us. Many countries have reinstated travel bans. Despite these, new cases have been reported across Europe.
Scientists are looking at the dangers Omicron might pose. They found 50 genetic changes in the DNA in the spikes of the virus. Vaccines focus on these spikes. Any changes in their DNA could make the virus more dangerous, spreadable and resistant against vaccines. The White House warned that: "When you have a virus that is showing this degree of transmissibility, and you're already having travel-related cases…it is ultimately going to go all over."
