Flu Prevention Symbol - Public Health Warning Sign #121064 (License: Personal Use)

This image features bold black uppercase letters spelling “FLU” centered within a white circle, which is overlaid by a thick red diagonal slash-forming the standard international prohibition symbol. The high-contrast design ensures immediate recognition and is commonly used in health campaigns to emphasize flu avoidance, vaccination importance, or infection control measures.

Used on public health websites, CDC or WHO informational pages, vaccination campaign materials, school or workplace wellness notices, and digital signage during flu season to communicate prevention and risk reduction.
