What Are the Newest Traits?
The present COVID-19 surge seems to be on the highest level for the reason that Omicron variant contaminated tens of millions in December 2022, in accordance with the CDC’s COVID wastewater knowledge. Check positivity seems to be stabilizing after growing since November, the CDC’s COVID Knowledge Tracker reveals, although the speed was nonetheless excessive at 12.7% positivity through the first week of January.
