As cases of coronavirus variants are reported in the US, the new director of the Centers for Disease Control and Prevention says we have to treat every COVID-19 case as if it's a variant.
Dr. Rochelle Walensky said officials were ramping up tracking of the variants but urged Americans to continue to wear masks and social distance, during a COVID-19 briefing on Friday .
"By the time someone has symptoms, gets a test, has a positive result and we get the sequence, our opportunity for doing real case-control and contact tracing is largely gone," Walensky said. "We should be treating every case as if it's a variant during this pandemic right now."
Walensky said 379 cases of the B.1.1.7 variant which was first detected in the United Kingdom have now been confirmed across 29 states.
