COVID-19 is primarily spread person to person via respiratory droplets or small particles, like aerosols. If infectious respiratory droplets land on objects (such as cash or change), and someone touches the object and then touches his/her mouth, eyes or nose, then he/she may get COVID-19. In general, it is important to maintain excellent hand hygiene, especially after touching commonly used items, such as money.
