Face masks had a significant impact during the COVID-19 pandemic by reducing the spread of the virus. They served as a barrier to respiratory droplets, which are a primary transmission method for COVID-19. Wearing masks became a key public health measure, especially in crowded and indoor settings, helping to protect both the wearer and those around them. Masks also became a symbol of collective responsibility and solidarity, though they were sometimes a point of political and social contention. Overall, widespread mask usage contributed to controlling outbreaks and saving lives.
