新冠是怎麽一年一年地延續下來而不能被人類撲滅的？
COVID is still causing the most number of cases, the most number of hospitalizations and the most, unfortunately, number of deaths that we’re seeing week over week,” Dr. Mandy Cohen, director of the CDC, said in an online discussion Tuesday. “So while we all wish we could leave COVID in the rearview mirror, it is still here with us, and so we need to make sure we are continuing to take it very seriously.”
Cohen last week urged people to take precautions such as getting vaccinated, avoiding people who are sick and staying home when ill, regular hand-washing, improving air ventilation and wearing a mask.
