As authorities revealed that a new Covid-19 variant has been detected in the US, medical experts are emphasizing that high-risk persons resume masking to prevent potentially deadly infection. Warnings from these physicians come amid an ongoing increase in Covid-19 hospitalizations.

The US Centers for Disease Control and Prevention (CDC) has said that scientists have discovered a new coronavirus variant, BA 2.86, during routine monitoring of wastewater. Officials said that this variant’s “large number of mutations” has prompted concerns that it could evade immunity derived from vaccination and prior infections more than other variants.
