Mask mandates are rules set by governments or health authorities requiring people to wear face masks in certain public spaces. These mandates aim to reduce the spread of respiratory illnesses, particularly during outbreaks like the COVID-19 pandemic. They are often implemented in places such as schools, public transportation, and indoor venues. The effectiveness of mask mandates can vary based on factors like community compliance and the type of masks used. Studies have shown that wearing masks can help protect both the wearer and others by reducing the transmission of viruses, making them a key public health measure during health crises.
