New York City is no longer the metro area with the most new coronavirus cases each day in the U.S. In fact, it's not even in the top 20, per Nephron Research. Neither is Boston, D.C., San Francisco or Detroit.

Between the lines: We may still be in the first wave of the coronavirus pandemic as a country, but this phase of it looks very different than the first.

  • Although Los Angeles and Chicago are still adding a lot of new cases each day, the number of cases is decreasing over time. In cities throughout the South and the Sunbelt, cases are increasing — and in some instances skyrocketing.

Yes, but: Now that we as a society have more information about the coronavirus, who is getting it may look different than it did earlier, especially if vulnerable people continue social distancing.

  • In Tennessee, for example, younger people have made up a higher portion of new cases than they did earlier on in the pandemic, according to a recent Vanderbilt report.

Coronavirus cases rise in 22 states

The coronavirus is surging once again across the U.S., with cases rising in 22 states over the past week.

The big picture: There isn't one big event or sudden occurrence that explains this increase. We simply have never done a very good job containing the virus, despite losing 200,000 lives in just the past six months, and this is what that persistent failure looks like.

Young people accounted for 20% of coronavirus cases this summer

People in their 20s accounted for more than 20% of all COVID-19 cases between June and August, analysis from the Centers for Disease Control and Prevention shows, bringing the median age of coronavirus patients to 37, down from 46 in the spring.

Why it matters: Young people are less vulnerable to serious illness, but they contributed to community spread over the summer, the analysis says — meaning they likely infected older, higher-risk people, especially in the South.

Where bringing students back to school is most risky

Schools in Southern and Midwestern states are most at risk of coronavirus transmission, according to an analysis by Coders Against COVID that uses risk indicators developed by the Centers for Disease Control and Prevention.

The big picture: Thankfully, schools have not yet become coronavirus hotspots, the Washington Post reported this week, and rates of infection are lower than in the surrounding communities. But that doesn't mean schools are in the clear, especially heading into winter.
