Coronavirus cases are once again surging in several European countries, potentially signaling that the U.S. will soon experience another spike as well.
Between the lines: Several factors are likely at play, including relaxed mitigation measures, the spread of the B.A.2 variant and waning vaccine protection, tweeted Scripps Research's Eric Topol.
State of play: Cases are still plunging in America, and hospitalizations are at their lowest level since last summer.
- As we've learned over and over again, the virus can still come surging back. However, previous infections and vaccinations will likely prevent most cases from becoming severe if there's another wave.
