The American Psychiatric Association (APA) says it is not allowing people to wear masks or face coverings for Halloween.
However, many have asked for them.
In a statement on Thursday, the APA said it is “not in the business of providing guidance on public safety and public health.”
But many have called on the organization to make Halloween masks mandatory.
Some have also called for a ban on facial coverings.
Some say the masks are a way to combat the flu pandemic.
But others say the mask is a symbol of powerlessness.
The masks can be used to conceal or disguise an identity or hide a face.
It has been a popular Halloween costume for many, with people dressing up as Santa, zombies, ghosts, vampires and other popular characters.
The costumes also are sometimes worn as Halloween costumes to trick-or-treaters.
For the past few years, there have been reports of the flu among people in the U.S. living in the Midwest, including in Indiana, Michigan and Wisconsin.
People have also reported having trouble breathing, or having trouble swallowing the water.
There have also been cases of dehydration.
The flu is believed to be spreading to many more people in some parts of the U, including states such as Texas and Florida.
There have been no reports of any deaths.
