For holiday parties, CDC recommends the use of a “window fan”.

The U.S. Centers for Disease Control and Prevention published recommendations for the upcoming Christmas season on Saturday, including the idea of ​​using a window fan to keep the air as fresh as possible at an indoor party.

The CDC appears to be suggesting that the circulating air indoors can ward off airborne coronavirus, or at least reduce the likelihood of it spreading to home gatherings.

“If you are celebrating indoors, try to get some fresh air by opening windows and doors,” says the Holiday Party Instructions. “You can use a window fan in one of the open windows to blow air out of the window. This draws fresh air in through the other open windows.”

That said, even if the worst pandemic wave of summer could be over, the CDC would much rather that Americans not gather indoors with loved ones or visitors this winter.

It is advisable to only get together with members of the same household, virtually meet distant family and friends or, if necessary, “hold an outdoor celebration where everyone is at least 2 meters apart”.

Those who have to venture to events should be vaccinated, the CDC said. And they should wear masks even when there are outdoor parties in communities with high rates of Covid-19 spread or when the vaccination status of others is unknown, the CDC said.

The agency said unvaccinated people should not travel, pointing out that masks are still required on public transport.
