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. But there is no evidence so far that the standard prevention strategies, including vaccination, masking, distancing, ventilation and hand-washing are not effective in reducing the risk of infection or transmission., For omicron, there are very limited data on this, Bollinger says. CDC is working with many public health officials and partners to monitor all variants. The drill will test the countrys ability to coordinate and manage things like local/regional lockdowns, monitoring and oversight of the new variant, including vaccine testing, providing economic support for the population and ensuring that the education system can successfully adjust.
