A new Covid variant is spreading across the U.S. and it may be able to evade protection from current vaccines.
The variant, known as BA.3.2, has been detected in nasal swabs taken from four American travelers and clinical samples from five patients in four unidentified states. It’s also been found in three airplane wastewater samples and 132 wastewater samples taken in more than 20 states, suggesting that its reach is actually far more widespread than what scientists see right now.
