As coronavirus infections rise in parts of the world, experts are watching for a potential new surge in the U.S. Recent developments have experts worried about how long a new surge will take to detect.
“We’re not in a great situation,” said Jennifer Nuzzo, a Brown University pandemic researcher.
a coronavirus variant — the descendant of omicron known as BA.2 — seven days earlier than any other reported detection in the U.S.But it’s different elsewhere. The World Health Organization this week reported that the number of new coronavirus cases increased two weeks in a row globally, likely because COVID-19 prevention measures have been halted in numerous countries and because BA.2 spreads more easily.BA.2 accounts for a growing share of U.S.
Tallies of test results have been at the core of understanding coronavirus spread from the start, but they have always been flawed. Mara Aspinall is managing director of an Arizona-based consulting company that tracks COVID-19 testing trends. She estimates that in January and February, about 8 million to 9 million rapid home tests were being done each day on average — four to six times the number of PCR tests.HUNTING FOR VARIANTSA year ago, the agency signed deals with 10 large labs to do that genomic sequencing. The CDC will be reducing that program to three labs over the next two months.
Researchers have linked wastewater samples to the number of positive COVID-19 tests a week later, suggesting health officials could get an early glimpse at infection trends. “It’s a really important and promising strategy, no doubt. But the ultimate value is still probably yet to be understood,” said Dr. Jeff Duchin, the health officer for Seattle/King County, Washington.Last month, the CDC outlined a new set of measures for deciding whether to lift mask-wearing rules, focusing less on positive test results and more on hospitals.
