There's A New COVID-19 Variant Called FLiRT: Here's What You Need To Know About It
A new set of COVID-19 variants, nicknamed FLiRT, has been detected in wastewater surveillance, according to data from the Centers for Disease Control and Prevention. From April 14 through April 27, the variant, labeled KP.2, makes up about 25% of the cases in the United States, according to the CDC. That makes it the new dominant variant in the country, overtaking JN.1. The JN.1 variant, which spread globally over the winter, made up 22% of COVID-19 cases in the U.S. in the same two-week span.KP.1.1, another FLiRT variant that is circulating, made up about 7.5% of COVID-19 cases in that two-week span, according to CDC data.

With H5N1 Avian Flu Silently Spreading In US Cattle, Wastewater Testing Could Be Key
Over a year ago, Marc Johnson, PhD, of the University of Missouri, developed a probe to detect H5 avian influenza A virus (IAV) genetic material in city wastewater because he expected it to start popping up in routine surveillance—just not from cattle. "This cattle thing, that snuck up on us," he told CIDRAP News. "If this [probe] had been implemented nationally, we would've known about this in wastewater back in February, and they would have maybe gotten a lid on it sooner. It's really surprising that it became so widespread without anybody knowing." But the probe wasn't operationalized at that time because H5N1 wasn't recognized until some cattle started showing symptoms in late March. (Van Beusekom, 5/7)
