The CDC on Monday updated its guidance to acknowledge that COVID-19 can be spread through the air, particularly in poorly ventilated areas.

Why it matters: Consensus has grown that the coronavirus can be spread via lingering particles and droplets in the air by people more than six feet apart under certain conditions — though the CDC still says that spread mainly occurs through close contact with an infected person via larger respiratory droplets produced by coughing, sneezing or talking.

  • The update follows an error from the agency last month when the updated guidance was accidentally published without review.

What they're saying: "Today’s update acknowledges the existence of some published reports showing limited, uncommon circumstances where people with COVID-19 infected others who were more than six feet away or shortly after the COVID-19-positive person left an area," the agency said.

  • "In these instances, transmission occurred in poorly ventilated and enclosed spaces that often involved activities that caused heavier breathing, like singing or exercise. Such environments and activities may contribute to the buildup of virus-carrying particles."

An outbreak of COVID-19 has struck the White House — including the president himself — just weeks before the 2020 election.

Why it matters: If the president can get infected, anyone can. And the scramble to figure out the scope of this outbreak is a high-profile, high-stakes microcosm of America's larger failures to contain the virus and to stand up a contact-tracing system that can respond to new cases before they have a chance to become outbreaks.

Polish President Andrzej Duda has tested positive for the coronavirus, a spokesperson announced on Saturday.

The big picture: Duda is reportedly feeling well and in isolation. His positive test comes amid a massive uptick in COVID-19 throughout the country and elsewhere across Europe.

  • Poland had previously warded off the virus with relative success, but is now facing a massive influx of cases that threatens to overwhelm its medical system.
  • The nation on Saturday tracked "13,628 new cases and 179 new deaths — a record number of deaths in one day since the start of pandemic," AP reports.
