"China needs to share clinical information on people infected in order to see how the variant behaves in a non-immune population," Prof Heymann said. Initial data for the omicron XE variant suggests that the growth rate (that is, the proportion of new infections in the population) is slightly higher than that of omicron BA.2. Some variations allow the virus to spread more easily or make it resistant to treatments or vaccines. The original Omicron strain (BA.1) was first identified in Botswana and South Africa in late November 2021, and cases quickly began to surface and multiply in other countries. Note: Information provided in Yale Medicine articles is for general informational purposes only. The Spanish press reported infections of their royal family (even though British royals were suffering at the same time), thereby creating a label that persists to this day.

That means that, in addition to staying up-to-date with their vaccines, people were advised to practice such strategies as washing hands, wearing masks, and maintaining a physical distance from one another, especially when indoors in places where there was substantial or high transmission. Any COVID variant can cause long COVID symptoms but so far, we're seeing less long COVID with the Omicron variant and subvariants than with previous variants, like Delta. Prof David Heymann from the London School of Hygiene and Tropical Medicine acknowledged that there was still a fair amount to learn about this latest variant. His concern was for countries like China, where there was both low take-up of vaccines and little natural immunity because of prolonged lockdowns. The UK had five Omicron waves in 2022, and further spikes in cases seem inevitable. Accessed July 7, 2022.
