Though some colleges and districts are already utilizing the test-to-stay strategy, the C.D.C. had not beforehand endorsed it, citing a scarcity of proof. On Friday, the company launched research from two counties, one in California and the opposite in Illinois, that successfully examined the protocol and located that it labored.
The research have been performed earlier than the fast-moving Omicron variant started spreading in the US. Scientists are nonetheless investigating many fundamental questions concerning the variant, together with whether or not it will increase the danger of in-school transmission.
“Even with the latest enhance in Omicron variant, we count on that these prevention methods will proceed to work,” Kristen Nordlund, a C.D.C. spokeswoman, stated in a press release on Friday. “Nevertheless, as we be taught extra concerning the Omicron variant, C.D.C. will proceed to overview and replace steering as wanted.”
