In the West, people are taught to wear masks only when they get sick.

In Japan, wearing masks has long been seen as a manner to reassure others when one catches a cold or flu. Some Japanese also turn masks into fashion accessories (配饰), with different colors and patterns to match their clothes. Wearing masks is also a way to “hide” for young women when they don’t have their makeup on.

In more collectivist cultures in Asia, wearing masks might also be a symbol of solidarity during the outbreak, according to Lynteris. “Mask culture in Asia creates a sense of a fate shared, common obligation and civic duty.” People wear masks “to show that they want to stick together” in the face of danger, Lynteris wrote.
