In general, the risk is higher when a large number of people crowd together indoors with poor ventilation. Risk is higher if people are not wearing masks or are engaged in loud activities that propel their breath across the space, such as when singing, shouting, or breathing heavily from exertion. Increase the time spent in those circumstances and the risk is even more.
The researchers suggest consulting the “Traffic Light” chart to find the type of situation you will be in. If the color is green, the risk is relatively low, especially if you wear a mask and are not there for hours at a time. If the color is yellow, proceed with caution. Risk is at a medium level for “yellow” situations. In any situation, you can reduce the risk by wearing a mask and remaining for as short a time as possible. If the color is red, that means stop. Avoid any “red” situations if possible. If you must go, wear a mask, minimize the duration of your visit, and wash your hands and use hand sanitizer both during the activity and immediately upon leaving and then again when arriving at home. And change your clothes.
Using this color-coded chart can help us make better informed decisions, reduce our personal risk of infection, and — hopefully — our levels of anxiety until a vaccine arrives.
