Emojis in public health and how they might be used for hand hygiene and infection prevention and control

Emojis are frequently used picture characters known as possible surrogates for non-verbal aspects of behavior. Considering the ability of emojis to enhance and facilitate communication, there has been a growing interest in studying their effects in scientific and health-related topics over the past few years. Infection prevention and control (IPC) is a field of medicine that is directly associated with specific behaviors. These include hand hygiene, which is the cornerstone of the prevention of healthcare-associated infections, and essential in stemming the spread of antimicrobial resistance. This paper aims to provide an overview of how emojis have been used in the medical and public health literature and proposes their possible use in IPC and hand hygiene to put forth a vision for the future research.
